We use simple mathematics — 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.
