THE FACETCAM REFERENCE
How light behaves inside a cut stone.
The physics FacetCAM's renderer implements, written for anyone who works with stones — the same reference our own workspace ships. No sign-in needed.
GEM OPTICS
The Science of Sparkle
Why a diamond dazzles and glass just sits there — refractive index, Snell's law, total internal reflection, Fresnel reflection, fire and Beer-Lambert absorption, with the equations and the numbers for eleven gem materials.
SYNTHESIS
How a diamond is grown
MPCVD reactors and six-anvil presses, from the machine hall down to the chemistry — with interactive cutaway diagrams, sourced machine specifications, diamond types and how grown stones are told apart.
GLOSSARY
The language of faceting
Barion to windowing: the terms cutters actually use, each with a plain definition and the detail behind it.
