About this app

GemID is a gemstone identification tool built around the properties gemologists
actually measure: refractive index, specific gravity, fluorescence, pleochroism,
and optical character.

Enter your instrument readings and GemID narrows the candidate list in real time —
then recommends the next test most likely to distinguish between remaining
candidates. No guessing. No photos. Just systematic, property-driven ID.

WHAT'S INSIDE
119-gem database covering natural, synthetic, and simulant entries. Decision engine
filters candidates as you add readings. Next-test recommendations guide you step by
step. Natural vs. synthetic testing workflow. Treatment detection covering heating,
filling, irradiation, and more. Examination Record for shareable PDF/HTML client
reports. Valuation context with per-carat market ranges. Session saves to your
account for later reference.

WHO IT'S FOR
GemID is built for gemologists, jewelers, appraisers, and serious collectors who
work with a loupe, refractometer, and scale — not a camera.

Results are described as "consistent with" or "candidates include." GemID is a
reference and workflow tool, not a replacement for professional judgment.

PLANS
Free includes a 14-day Pro trial. Hobbyist covers core ID, saves, and statistics.
Pro adds nat/syn testing, treatment detection, Examination Records, export, and
client metadata.
