Having various precision instruments

A single loupe is not enough for modern trade. Gemstone Laboratory keeps a suite of instruments so diamonds, colored stones and treated material can be documented in one place.

Refractometers, balances, microscopes and lighting setups sit beside record-keeping. The goal is not a shop-floor estimate. The goal is a GRA document with a number that can be searched years later.

If you hold a report, use Certificate No. on the Certificate page. If you are preparing a submission, photograph the stone under clean light and keep any prior paperwork — both help the bench team work faster.
