Alexandra Schwarzwald

Meet our founder Alexandra Schwarzwald, the creative mind behind Fine Principles. With a keen eye for detail and a visual vocabulary that speaks the language of geometry and grids, Alexandra uses the potential of folding techniques and creates multi—faceted jewellery according to a meticulous principle of order.

But let’s start from the beginning. After completing her BA in Communication Design in 2015, Alexandra discovered the passion for jewellery making. She shifted her focus from graphics to object design and started crafting wax models by hand. At the start of her journey, she was already taking a systematic approach to her studies. So, she delved into facets and their impact on various dimensions.

Alexandra was on a mission to discover new design possibilities, and she decided to dig into the world of digital folding. With a newfound excitement for 3D modelling, she decided to shift her focus from analogue wax work to digital, where she recognized a great potential in this field.

In August 2021, she took a creative break and explored shapes resulting from a variety of folding grids. Months of testing and prototyping later, her first collection, ‘Series XF’ was finally ready to be shown to the world. The reveal happened at the BLICKFANG design fair in Hamburg in October 2022, where the jewellery was presented to the public eye.

 
Alloy (= Legierung)

Well, let us break it down for you in simple terms. An alloy is a composition of two chemical elements, one of which is always a metal. This blend results in a material with improved properties, making it more durable than its individual components.

As pure precious metals are too soft for jewellery processing, additional metals such as copper, tin, bronze, or brass are added to the precious metals. These make the piece of jewellery harder and more resistant to corrosion.

Depending on the mixing ratio, different shades such as yellow, red, rose or white gold can also be achieved by adding silver, or copper. Less well-known gold alloys are green, blue, or black gold.

Alloys also play an important role in the processing or function of the piece of jewellery. Although 18k gold alloys are of higher quality, they are also softer and not really suitable for work-intensive activities, especially in the case of rings. Therefore, 14k gold alloys are preferred for everyday use in order to guarantee longevity.

Bauer Walser is one of three refineries near Pforzheim from which our partner foundry Kalman Hafner sources certified and recycled materials. The company Bauer Walser for precious metals and semi-finished products is a member of the RJC (Responsible Jewellery Council) and holds RJC CoC (Custody of Chain) and RJC CoP (Code of Practices) certifications. This ensures transparency throughout the entire supply chain process to guarantee our jewellery is responsibly sourced.

 
Berlin
Berlin is the birthplace and founding location of Fine Principles. And of course, the founder Alexandra is from Berlin as well.
 
Bronze

Please do not get confused — bronze is not a precious metal. It is merely an alloy consisting primarily of copper and tin, to which other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals are often added. 

C
Carat (= ct)

‘Carat’ (or metric carat = ct) is used as a unit of measurement and indicates the mass of gemstones.

Originally, carat weighed as much as a dried carob seed, in the Middle Ages as much as three grains of barley or four grains of wheat. In order to standardise the differences across national borders, the values were adjusted at the beginning of the 20th century. Since 1907, exactly 2 milligrams (0.2 grams) has equated to one metric carat.

 
Certification (= Zertifizierung)

The caster we work with purchases recycled precious metals from local suppliers near Pforzheim with RJC (Responsible Jewellery Council) certification. They follow the standards of RJC CoC (Chain of Custody) and RJC CoP (Code of Practices). In other words — RJC is the world’s leading sustainability organisation in the jewellery industry.

Both, the caster and goldsmith comply with REACH regulations throughout the entire supply chain. REACH stands for Registration, Evaluation, Authorization, and Restriction of Chemicals and is a regulation of the European Union (EC) No 1907/2006.

Additionally, the caster receives ‘fair gold’ from Fairever, which is a certified supplier of Fairtrade gold and silver and an authorised supplier of Fairmined gold and silver.

 
Concept (= Konzept)

Matched by ’logic & beauty‘ — these are the two components that make up Alexandra’s jewellery. They follow mathematical and design principles to support the clearly structured concept and allow scope for further series.

More precisely, Alexandra speaks the visual language of geometry and grids. She uses the potential of folding techniques and follows a meticulous principle of order. By combining simple principles, she transforms folding grids from 2D into 3D and creates multi-faceted jewellery.

D
Here is a brief excursion into the world of German accuracy. The DIN 824 standard published by DIN (Deutsches Institut für Normung e.V.) in March 1981 defines the folding of technical drawings and other documents for filing in document containers.

A distinction is made between three forms — A, B, and C. Folding DIN 824-A-4 refers to folding with stapling and a folded-out stapling edge and 4-hole punching. DIN 824-B refers to folding with stapling and a folded-out stapling edge and an additionally attached stapling edge. Finally, DIN 824-C refers to folding without stapling. Now it is your turn.
F
Facet (= Facette)

We have all heard the term ‘facet’, but few can describe it accurately. The word itself derives from the Latin ‘facies’ (meaning ‘front side’ or ‘face’) and is basically nothing more than a flat or smooth surface on a geometrical shape. Thus, facets find their use in stone carving, dental technology, art and printing, or can even be found as part of a personality trait in psychology.

Our facets are created by folding techniques — more precisely, by the ‘X-Form’ grid. By adding or taking them away, different dynamics and structures are created that have a technical-minimalist or organic-floral appearance.

 

The caster we work with, Kalman Hafner, purchases ‘fair’ gold and silver from Fairever. To support workers dependent on small-scale mining, Fairever purchases gold and silver directly from responsible mines.

Fairever goal is to ensure the workers live a safe and healthy life as part of an intact society and environment. It is important to support local communities, especially small-scale producers, through Fairtrade and Fairmined certifications. Obtaining these certifications ensures that fair working conditions and equitable compensation are part of the supply chain.

With its commitment to Fairtrade and Fairmined, as well as sustainable mining practices, Fairever stands out by believing in the power of ethical jewellery to create a positive impact on communities and the environment.

Learn more about Fairever →

 

Did you know that there is a special kind of gold that is mined in a way that is better for both people and the environment, than gold from uncontrolled mines?

It’s traceable gold from Fairmined, and it comes from small-scale mining organizations that are certified to the Fairmined standard. This means that the gold has been extracted in a way that is respectful to nature, supports sustainable development, and helps to improve the lives of the people who live in these communities.

We offer Fairmined Precious Metals for individuals seeking responsibly sourced gold that makes a positive impact on mining communities’ economy, society, and environment.

Fineness (= Feingehalt)

‘Fineness’ is a unit of measurement and indicates the ratio in which a valuable element is contained in a precious metal alloy.

As we learned in chapter ‘alloy’, fine gold is the name for pure gold, i.e. a metal that has an alloy with at least 99.99% gold. This alloy is commercially available as 999.9‰ fine gold and is rated at 24 carat.

As well as fine gold, fine silver is another material that creates the basis for high-quality jewellery. Fine silver is usually further processed as a component of alloys because, in its purest form, it is very soft and cannot be easily used as a base material for jewellery. Therefore, silver often occurs as sterling silver, a silver alloy with 93.5% or 92.5% fine silver content. The rest of this alloy is typically made up of copper.

 
Fine Jewellery (= hochwertiger Schmuck)

The term ‘fine jewellery’ is used for all jewellery made from precious metals such as gold, silver, or platinum. Real gemstones such as diamonds, sapphires, rubies, or emeralds are usually used for fine jewellery.

In contrast, ‘costume’ or ‘fashion’ jewellery refers to any jewellery that is not made from precious metals. Fashion jewellery is sometimes referred to as ‘junk jewellery’ and is often made from cheap base metals such as brass, copper, or aluminium. It can also be made from textiles or leather, or base metals plated with precious metals. If a piece of fashion jewellery is decorated with a gemstone, it is almost always an imitation gemstone, i.e. the ‘gemstone’ can be made of plastic, glass, or crystal, among other things.

Fine jewellery is designed to last a lifetime and can even be passed down through generations. When fine jewellery breaks, it can usually be repaired. In addition, fine jewellery retains its value in the future.

 
Fine Principles
Due to an enthusiastic urge for diverse forms of expression, FP draws on the aesthetic potential of folding techniques and conceives multi–faceted jewellery with sophisticated precision.

Through the interplay of thought–out principles and certified precious metals, FP creates authentic designs that are characterized by graphic regularity and come from sustainable production.

Folding (= Faltung)
Fine_Principles_Nature_Folding_01

The term ‘falten’ (to fold) is firmly anchored in our language — according to DWDS (Digitales Wörterbuch der deutschen Sprache), the Old German word ‘faldan’ first appeared around 800 AD and developed over the following centuries from ‘valten’, ‘valden’ to ‘vōlden’, and in the ninth-century from ‘faldōn’, ‘faltōn’ to finally ‘falten’. There were also various meanings in circulation, such as ‘to bend’, ‘to fold’, or ‘to bend over’.

‘Folding’ has multi-layered meanings and is in the truest sense a product of nature. In the course of our evolution, landscapes have folded, as well as leaves, flowers, buds, shells, snail shells, mushroom caps, insect wings, and much more. We ourselves carry it on our skin and even in our bodies as a helical double helix — DNA.

Scientists, engineers, mathematicians, educators, artists, designers, and hobbyists of all ages continue to be fascinated by folding. It is not just paper creasing but can be transferred from 1D to 2D to 3D and is independent of materials.

The German educator Friedrich Froebel recognised the potential early on and incorporated it into his ‘Spielegaben’. Josef Albers and Paul Jackson, for example, also used paper folding to teach their students an understanding of geometry, spatial thinking, or simply artistic expression.

Many remarkable inventions have emerged from science and technology that have found their inspiration in folding. For example, the airbag, or tiny origami robots that enter the stomach via a capsule and can be controlled from the outside when unfolded.

 

Friedrich Wilhelm August Froebel (* 21.4.1782 Oberweißbach in Thuringia, † 21.6.1852 Marienthal near Bad Liebenstein in Thuringia) simply has to be mentioned here because he saw the potential of simple geometric shapes over 170 years ago and incorporated them into his teaching methods.

Froebel was a German educationalist, pedagogue and vocational school teacher and is recognised as the inventor of the kindergarten. He developed the system of toys and activities (‘Spielgaben und Beschäftigungen’), which were simply referred to as ‘Froebel’s Toys’. These could be stacked, laid, moved, folded, cut, pulled, plaited, laced, woven, sewn, stitched, modelled or kneaded. Fröbel wanted to use ‘play’ to stimulate the child’s independence, dexterity, haptic experience, creativity, motor skills and capacity for abstraction.

G
Galvanic (= Galvanik)
To put it simply, the galvanic process uses an electrolyte bath to create metallic coatings on objects. Learn more about the process in section P — (galvanic) plating.
 
Geometric Series (= Geometrische Serie)
Fine-Principles_Mathematics_01

We use a mathematical number sequence — in our case the Geometric Series — as a useful tool. To limit and control the folds, we take the approach of doubling (1, 2, 4, 8, etc.) and halving (1, 1/2, 1/4, 1/8, etc.), both in the number of facets and dimensions.

Four of our six categories strictly follow the rule. However, since rings and bangles correspond to natural body measurements, they are each drawn and adapted separately.

H
Hallmark (= Punzierung)
Fine_Principles_Process_Goldsmith_01

This refers to the embossed or stamped symbol in a precious metal that provides information about its fineness.

In Germany, the most common stamps are 333, 585 and 750 for gold, 835 and 925 for silver and 950 for platinum. These are not mandatory, but the legal text states that the fineness must be indicated with whole number thousandths, (§2 Para.1, §3, §5 Para.1 FeinGehG).

Legal regulations on hallmarking vary from country to country. England, for example, has been using and controlling hallmarks for over 700 years, and counterfeiting is still punishable by law.

Fine-Principles_Hermann_Gloeckner_Figura

Hermann Gloeckner (* January 21, 1889 in Cotta near Dresden; † May 10, 1987 in Berlin) was a German constructivist painter, sculptor, artist and graphic artist. Over five decades, the theme of folding was a constant companion, creating works in one-, two- and three-dimensional form.

I
ID
Our pieces have an ID consisting of a number and letter code. For example, behind XFCE64S2 is the series ‘X-Form’, the object ‘Circle Earring’, the number of ‘64’ facets, the size ‘S’, and the material thickness of ‘2’.

In the case of creoles, exactly ¼ of the facets are missing. However, they are described with a complete number since the design is based on circle earrings. And we only count the facets that define themselves according to the grid and not the endings or beginnings.
J
Jewellery (= Schmuck)
Fine-Principles_Design_01
The term ‘folding’ is deeply rooted in our language and has a multi-layered meaning. Folding is a product of nature and fascinates scientists, mathematicians, educators, designers, and hobbyists of all ages alike.

The grids of folding techniques can form their own dynamics simply by manipulated like squeezing, stretching, multiplying or even combining. Playing with folding holds enormous potential for design possibilities, which we want to exploit in the future.
 

Josef Albers (* March 19, 1888 in Bottrop; † March 25, 1976 in New Haven, Connecticut) was a German-American painter, art theorist and educator. His most famous work is probably his colour square painting ‘Homage to the Square’, which is one of the pioneers of Op Art, optical art.

In addition to his studies on colour theory, Albers also devoted himself to the subject of folding. As early as the 1920s, Josef Albers taught folding techniques at the Bauhaus in order to provide his students with solutions to problems. He encouraged students to plan their folded paper models in advance to ensure that the economy of form was in proportion to the expected amount of material and labour.

Karat (= k, Kt)
In jewellery processing, the ‘karat’ (carat = c, Ct, UK spelling) refers to the mass percentage of the highest quality precious metal in an alloy.

In Germany, ‘karat’ is specified in parts of 1000 in accordance with the fineness law, e.g. the gold content of 750 gold is 75%. Jewellery with 24 karat therefore consists of pure gold — 99.99%, to be precise — and means that no other alloying metal has been added.
L
Lost-wax process (= Wachsausschmelzverfahren)
Fine_Principles_Process_Moulding_03

Casting is a craft that has been used for thousands of years and became possible with the development of brick kilns around 3000 BC. Various processes have developed since then, such as centrifugal casting, die casting, continuous casting, mould casting, to name a few.

Our partner Kalman Hafner is specialised in investment casting, and brings our jewellery to life using the so-called ‘lost-wax process’. In this process, a duplicate is cast from an original in several complex steps:

  1. Modelling the wax model
  2. Mounting sprues on the wax model
  3. Preparation of the mould material
  4. Coating the wax model with moulding material
  5. Melting out the wax model
  6. Pouring molten metal into the hollow mould
  7. Solidification of the metal in the mould
  8. Breaking up the moulding compound and removing the raw casting


The finished raw casting is then sent for quality control and, if accepted, to the goldsmith. The goldsmith cleans the model so that the finished master serves as a template for duplicates.

If music is maths made audible,
origami is maths made visible.
— Paul Jackson

P

Since 1983, Paul Jackson has been a professional paper folder, paper artist, paper engineer, author, and teacher specialising in origami and the art of folding. In addition, he ventures into other worlds and explores folds in pedagogy, mathematics, physics, music, and of course nature.

Paul Jackson has written over 40 books and taught students in design fields such as architecture, fashion, ceramics, jewellery, product design, and textiles at more than 80 universities and colleges in 13 countries.

Together with his wife, Israeli origami artist and educator Miri Golan, he founded the ‘Folding Together’ project and launched the ‘Origametria’ program, which uses origami to teach geometry. Since 2018, it has been included in the national mathematics curriculum by the Israeli Ministry of Education.

Today, more than 30,000 primary school-aged children learn origami every week to strengthen self-esteem, but also to develop motor skills, hand-eye coordination, logical thinking, concentration, aesthetics, three-dimensional perception, and the basics of geometry.

Pforzheim
Pforzheim — formally ‘Portus an der Enz’, a Roman settlement founded in 90 BC — is a large city in the Black Forest with a long history for goldsmiths, jewellery artists, designers, and jewellery lovers. With over 250 years of jewellery and watch traditions, Pforzheim remains a Mecca for all things jewellery-related still to this day.

Additionally, it is still home to a number of jewellery-related exhibitions and cultural centres, such as:

Schmuckmuseum Pforzheim →
Pforzheim Galerie →
Schütt Edelsteinausstellung →
Technisches Museum der Pforzheimer Schmuck- & Uhrenindustrie →
 
Plating (= Vergoldung)
In the process of (galvanic) gold plating, a distinction is made between two types (2 & 3) of coating — one is a high-quality gold plating, the other merely a gold colour.

  1. The most durable form is of course the solid material from which a piece of jewellery is crafted. Quick reminder — we also offer customized solid alloys such as Fairmined gold. Just contact us for a quote →

  2. High-quality gold plating is achieved when it is applied to silver objects with a layer thickness of at least 3 microns. This type is named after the French word ‘Vermeil’.

  3. Materials such as brass are used for costume or cheaper jewellery, which only have a layer thickness of less than one micron. This is less durable, and wears off very quickly, especially rings.
 
Precious metals (= Edelmetalle)

The three most common precious metals in jewellery processing are gold, silver, and, in recent years, platinum, but there are plenty more. Precious metals are rare and are mined under more difficult conditions, compared to sand, for example.

The special thing about these precious metals is that they are corrosion-resistant, meaning they hardly react to air or water. In ancient times, coins were usually made of gold or silver because they had a certain quality standard and were valuable. However, it occasionally happened that fraudsters filed gold off the edge of the coins and thereby enriched themselves. To stop these gold thieves, the fluted edge that we still know today was created.

A few facts about gold and silver mining — the largest producing countries in terms of gold reserves are China, Australia, Russia, and North America (USA and Canada). The leading countries in silver mining are Mexico, China, Peru, Chile, and Australia.

 
Process (= Prozess)
Fine_Principles_Process_Goldsmith_02

It currently takes several weeks to produce small quantities of our jewellery. This is because there are various complex processes going on behind the scenes.

But let’s start from the beginning. After examination folding techniques, basic ideas are drawn, finalised and 3D printed. After reviewing the prototypes and making any necessary adjustments, the CAD drawings are reviewed for feasibility. Once the design process is complete, the actual production takes place in five steps:

1. CAD works & 3D printing

Based on the CAD design, a model template is created, which is used to produce the final form. After plotting the file, the piece is handed over to the goldsmith, who trims and cleans the surfaces carefully by hand.

2. Moulding

After cleaning, a rubber or silicone mould is made. With this mould, all parts will be cast in the desired alloy in the future. To ensure a consistently high quality, the most modern wax spraying machines are used for production.

3. Lost-wax process

From a single piece to small quantities, the jewellery is cast with most modern vacuum casting machines in the selected alloy such as recycled silver, gold, or platinum — everything with more than five decades of casting experience.

4. Goldsmith works

Once the pieces have been cast, they are cleaned by hand and prepared for wearing. This includes, for example, soldering in ear-studs or attaching eyelets for chains. Afterward, the pieces are sandblasted to give them a matte finish.

5. Plating & quality control

The final step is the (galvanic) plating in the desired colour and thickness. The plating on our rings is thicker since they are more likely to come into contact with other objects. After a final quality check, your jewellery is then ready for delivery.

All this is done only by wonderful professionals who help transform ideas into concrete jewellery and bring them to life. Thank you!

REACH is the European Union’s Regulation (EC) No. 1907/2006 and stands for Registration, Evaluation, Authorization and Restriction of Chemicals.

The focus is on protecting human health and the environment from the risks posed by the use of chemicals. At the same time, it aims to improve the competitiveness of the chemical industry in the EU and promote alternative methods for harmful substances in order to reduce testing on animals.

Recycled precious metals (= Recycelte Edelmetalle)

Basically, there are two main differences between recycled and fair-trade precious metals — one is recycled, and the other comes from the ground.

Recycled gold or silver, for example, are obtained from the recovery of already processed metal from old jewellery, watches, coins, objects, and even electronic waste. After disassembly, the collected material is cleaned and melted together so that it can be put back into circulation as recycled gold and recycled silver.

Even if the precious metals are recycled, this is not 100% the case. Recycled silver consists of around 95% recycled material, gold in some cases only around 30%. This means that the rest is still mined and mixed in.

Another point in addition to using resources sparingly is reducing our ecological footprint. When recovering, cleaning and processing recycled gold, CO₂ emissions are significantly lower than the actual extraction of gold in mines. This is what the eco-balance of the NaGold project at the Pforzheim Institute for Industrial Ecology revealed: with around ten to 20 tonnes of CO₂ per kilogram of mine gold, recycled gold from high-quality electronic scrap performs surprisingly well with 53 kilograms of CO₂ per kilogram.

RJC (Responsible Jewellery Council) was founded in 2005 and is a leading global standards-setting organisation for the global jewellery and watch industry to promote sustainable supply processes.

RJC is the only ISEAL member for sustainable standards and practices in the jewellery industry. The code of conduct is based on the 17 SDGs (Sustainable Development Goals), and the ten principles of the UN Global Compact.

RJC CoC (Chain of Custody Standard) provides full transparency of traceable and responsibly sourced practices. The certification contains information on how products and their materials have been sourced, traced, and processed in the supply chain.

Furthermore, the CoC ensures that the procurement of the semi-finished products manufactured by RJC, LBMA (The Independent Precious Metals Authority), or RMI (Responsible Minerals Initiative) certified refineries is conflict-free.

RJC CoP (Code of Practices Standard) enables practices focussing on ethical, social, human rights and environmental requirements. CoP helps to measure practical action tasks, and is the only one that covers the entire supply chain of the jewellery and watchmaking industry.

FP_Fine_Principles_XF_Poster_01

‘Series XF’ is our first collection and is inspired by the ‘X-form’ folding technique. As the name suggests, the shape consists of a repeating pattern of triangles that resemble consecutive Xs.

The entire collection consists of 28 pieces and is divided into six categories — ring, bar earring, circle earring, bangle, pendant, and creole. The jewellery follows a timeless approach and is made for everyone.

Size guide (= Größenleitfaden)
FP_Fine_Principles_Size-guide_Ring_M_01
We use the International standard system ISO (8653:2016), which defines ring sizes in terms of the inner diameter of the ring and is measured in millimetres. All other sizes simply follow the centimetre measurement, and are translated into S, M, L, or XL.

Further information on dimensions and sizes can be found in our size guides. To determine the correct fit, we have prepared a document in which you will find measuring tools and templates to cut out. Just make sure that the document is not scaled when printing, as this would change the dimension of the jewellery.

Explore our size guide →
 
Surface processing (= Oberflächenbearbeitung)

We love the aesthetics of sharp edges, and we hope you do too. To maintain this particular feature, we leave the surface as pure as possible after casting. Accordingly, all our pieces have a slightly textured but shiny surface.

Just a quick reminder — A piece of jewellery can be worn every day, which means that plated rings and bracelets, in particular, can wear off more quickly than earrings. It is completely normal as they automatically come into contact with other objects. Hence, we offer a touch-up service in which the goldsmith cleans the surface, and plates your piece again.

Ask for the touch up →

 
Sustainability (= Nachhaltigkeit)

Our sustainability approach starts with the product, which is made from certified and recycled precious metals. Both the caster and the goldsmith work with local suppliers who are certified or authorised members of the RJC, Fairtrade and Fairmined, and comply with REACH regulations. Additional jewellery accessories, such as ear pins or chains, are also made from certified precious metals and purchased locally from Berlin.

Furthermore, the jewellery boxes are made of FSC®-certified MDF wood fibreboard covered with FSC®-certified black Soft Touch paper. They are shipped in FSC®-certified kraft cardboard. Additional marketing materials are made from 100% recyclable, compostable or FSC®/PEFC™-certified paper and is only produced in small quantities in Germany.

Sustainability within a company is much more complex than just looking at products or packaging. Many of us within the industry are already on the right track, but more can always be done. At Fine Principles, we will always work on continuing to improve our own internal standards — it’s a work in progress!

T
Tarnishing (= Anlaufen)
Pure metals are precious (noble) metals that react the least with other metals or elements in the air. However, since 99.9% gold or silver is too soft for everyday use in jewellery, so-called alloys are processed to harden it and make it easier to work with. This means that the higher the proportion of precious metal, the lower the likelihood of tarnishing.
 
Touch up (= Auffrischung)
A piece of jewellery can be worn every day, which means that plated rings and bracelets, in particular, can wear off more quickly than earrings. It is completely normal as they automatically come into contact with other objects. Hence, we offer a touch-up service in which the goldsmith cleans the surface, and plates your piece again.

Transformation (= Transformation)
Have you ever wondered how a 2D grid can be turned into a 3D object? Well, we like to call it transformation, and it’s the process of remodelling a flat surface into a three-dimensional structure using a 3D computer software. Think of a sheet of paper that turns into a bird through folding. We do the same thing here, but digitally!
U
Unisex (= Unisex)
Who doesn’t love edgy facets 😉

We’ve taken a systematic approach, making it easy for you to mix and match pieces based on your preferences, whether it’s by size, model, or colour. That’s why we believe that our jewellery is suitable for everyone. The possibilities are endless, so go ahead and have some fun with it!
 

Nowadays, it is more important than ever to think about the responsibility and conservation of our natural resources. Part of a strategically circular economy is ‘urban mining’, which aims to take into account all material flows from raw material extraction to waste management and to reuse the secondary materials obtained.

‘Urban mining’ is also used in metal processing by German refineries to recover secondary metals. Precious metals from e-waste, for example, are recycled and processed into secondary materials that are integrated into the circular economy.

With the help of ‘urban mining’, a more responsible approach is to be anchored in the jewellery and watch industry. This is because the mining of gold and silver is still an environmentally harmful and social problem that is associated with a wide variety of conflicts. An ethical standard along the entire value chain is therefore essential for both producers and consumers.

V
V–Fold
The universal ‘V-Fold’ is a common method for folding surfaces and forms which, when executed correctly, offers great potential for very complex objects. By changing the angle or adding several grooves, for example, different shapes and rhythms are created, offering a variety of expressive possibilities.
X
X–Form

XF is derived from the folding technique ‘X-Form’. As the name suggests, the X-shape consists of a repeating pattern of triangles that resemble successive Xs. Today, we find ‘X-Form’ in paper folding, of course, but also in sculpture, art, architecture, ceramics, graphics, and jewellery design.

3D

3D technology has long been an integral part of the jewellery industry. Among others, it consists of software that can be used to draw 3D models and hardware that can be used to print 3D models.

For us, 3D modelling gives us the freedom to create more complex and complicated geometries than possible by hand. In fact, Alexandra started out that way, but then deliberately switched to 3D modelling in order to explore the world of digital folding more efficiently.

With 3D technology, we can make customer-specific adjustments more quickly and produce in small series. All of this is done with the help of local workshops in Pforzheim, who implement our designs using 3D printing along with handcrafted methods.
