Gem intelligence
The stone is only the beginning.
Species, variety, treatment, cut, color, clarity and provenance all matter. The library separates observable beauty from the questions that require a qualified laboratory.

The Futures Desk
New tools. Higher standards.
Precision scanning, parametric modeling, laser welding and additive processes expand what can be tested and repaired. The strongest work treats technology as an instrument—not an aesthetic shortcut.
