We combine fine jewellery and principles of design & mathematics with each other. The term ‘Fine Jewellery’ refers to all jewellery made of precious metals such as gold, silver, or platinum. In our case, we use recycled, nickel-free, and certified materials from a German refinery. All our jewellery is handmade in small quantities in Pforzheim.

Unlike recycled gold, sustainable or fair trade gold still comes from mines. Although they are labelled with certificates such as Fair Trade, FAIRMINED, or IRMA (Initiative for Responsible Mining Assurance), they are difficult to assess from our point of view in terms of ethical and social conditions. Especially if you have not been there yourself and cannot see the conditions miners work in. That’s why we like to use materials that are already available — recycled metals from teeth, old jewellery, objects, or even e-waste.

We have lots of principles actually, but when it comes to our creation, we combine design with simple mathematics to form timeless jewellery objects.

Therefore, we use flexible folding grids and transform them from 2D to 3D. The aspects of mathematics take effect in the number of facets as well as in the dimensions. Four of our six categories strictly follow the ‘Geometric Series’. However, since rings and bangles correspond to natural body measurements, they are each drawn and adapted separately. In other words, nothing is scaled.

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 geometry. Thus, facets find their use in stone carving, cutting, geometry 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. These small triangles shape the appearance of our object and sometimes turn out larger and sometimes smaller. To achieve this, they are cast and then carefully trimmed by hand. To preserve the quality of the edges, we leave the matte surface largely untouched. But this also means that the objects can vary slightly, especially in very small sizes.

We love the aesthetics of sharp edges, and we hope you do too. If you still have questions about the surface and comfort, please contact us.

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 X’. For example, if you fold a ‘Heaven & Hell’, also known as ‘Salt & Pepper’, you get edges called ‘Valley’ and ‘Mountain’ folds in paper folding.

Unfolded, the result is a grid consisting of three horizontal, three vertical, three 90°, and three 180° diagonals. These lines form exactly 32 right triangles. In this way, flexible design grids are created through duplication or combination, which, transferred to 3D objects, take on a dynamic of their own.

Today we find the X-Form in paper folding, of course, but also in sculpture, architecture, graphic design, and installations. One artist, who creates metal, paper, and wood sculptures using folding techniques, is Peter Millett — enjoy exploring.

All 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.
