✦ Curated Collection

Signature Collection

Our hand-selected showcase of 190+ standout designs across every gemstone material. Browse the flagship Signature Picks or filter by refractive index below.

The higher the refractive index (RI), the more a designer can do with light. Less light leaks out through the back of the stone, and as light leaves through the top, the facets fan it out much more widely. Neighbouring facets end up “seeing” very different things — a bright light or your own shadow — giving crisper, higher-contrast patterns.
