A faceted iris, verified before a single facet was cut.
12 ct
Lab-grown blue sapphire, Czochralski-pulled
47 facets
Selected from 30 iris-candidate designs
3.1%
Window fraction — reads as an iris, not a flat window
30°
Tilt tolerance, 9.47° of pavilion margin to spare
Physics-verified, not eyeballed
Reproducible measurements a buyer can check, not just a pretty render.
30
Candidate iris cuts ray-traced
Every design in the reference library, re-traced at sapphire's own refractive index before any was ruled in or out.
5 / 30
Verified safe for corundum
Only five candidates were originally written for corundum's index — the rest needed re-angling or failed outright.
9.47°
Pavilion margin above critical angle
Cuttable exactly as specified, with room to spare — not a design that happens to work if the polisher is perfect.
0
Angles chosen by eye
Every facet angle in a signature cut is checked against ray-traced physics before it reaches the cutting wheel.
Signature Cuts
Studio-owned designs, sold exclusively by us.
Same process, other species
The verification method isn’t sapphire-specific.
Reference cuts from the craft-heritage library, re-rendered on turntable to show the same geometry check applied across species. These are heritage designs, not studio IP — see the Gem Library for full attribution.
Gem Library
Ten species, cross-checked against the same optical standard.
A sourcing reference of craft-heritage cut designs — historical, not studio-owned — spanning diamond, moissanite, ruby, sapphire, emerald, and more. Full designer credit and license terms on every spec sheet.
