Anatomy of a cut
Table
The largest facet. Light enters here first.
Crown
33 facets that split white light into colour: the fire.
Girdle
A band thinner than a hair, where the stone is held.
Pavilion
Angled at 40.75° so light turns back instead of leaking out.
Culet
The point. On an Orsay stone, polished to nothing.
