Ten species, cross-checked against the same optical standard.

Craft-heritage reference library — every cut design below is drawn from a historical faceting-design corpus with mixed third-party licensing (designer credits and license notes are shown on each spec sheet). The studio does not own and does not exclusively sell these historical designs. They are shown here for sourcing and educational context — to demonstrate the geometry our verification process can evaluate on any species. Our only studio-owned, exclusively-sold designs are Dragon Eye and Eye of Zul, under Signature Cuts.
