Morganite in Jart
The look in the studio's material library, with the values the renderer uses.
| Stone | Colour | RI | Dispersion C–F | Abbe | SG | Colour depth |
|---|---|---|---|---|---|---|
| Morganite | #f3ab9f | 1.58 | 0.009 | 65 | 2.72 | 10.3 mm |
RI refractive index (nd). Dispersion C–F nF − nC, the spread between blue and red light; many gem tables quote the B–G figure instead (diamond 0.044, here 0.025). Abbe number: lower means more fire. SG specific gravity, used for carat estimates in Design Facts. Colour depth the path through the stone after which white light takes the stone's full colour; shorter paths look paler.
How it renders
With a refractive index of 1.58, a polished morganite facet reflects 5.1% of light that meets it face-on (diamond: 17.2%). Light inside the stone that meets a facet more than 39.3° from straight on cannot leave and is reflected back in; the smaller that angle, the more light a good cut returns to the eye (diamond 24.4°, quartz 40.4°).
Its dispersion (C–F) is 0.009, 36% of diamond's, which sets how much fire, the flashes of colour, a render shows under small, bright lights.
Its colour builds slowly, over a longer path than any other coloured beryl preset, so it stays soft even in a large stone. Rose gold next to it warms it further.
