Scientific identification and origin analysis of natural gemstones — establishing what a stone is, where it came from, and whether it has been treated — with documentary precision for collectors, estates, and institutions.
Request IdentificationAnalytical Methods
01
Precise measurement of how light bends through the stone, establishing the foundational optical identity of every gem examined.
02
UV-Vis, FTIR, and Raman spectroscopy reveal the chemical composition, trace elements, and treatment history invisible to the naked eye.
03
Long-wave and short-wave UV fluorescence patterns provide critical diagnostic data for identification and treatment detection.
04
High-magnification microscopy documents internal characteristics — growth patterns, mineral inclusions, and structural features that establish geographic origin.
05
Hydrostatic weighing determines density to distinguish between gemstones with similar visual appearances but different mineral compositions.
06
Multi-method analysis establishing whether a ruby is Burmese, a sapphire is Kashmiri, or an emerald is Colombian — directly impacting market value.

Why Independent Identification Matters
Laboratory reports from independent gemologists carry authority in insurance claims, estate valuations, auction estimates, and private transactions.
GSBH identification reports are accepted by major insurance carriers, auction houses, and estate attorneys across the United States and internationally.
Every stone examined. Every conclusion documented. Every report defensible.
