Every stone,
documented.
Last updated: August 2026
Save identification sessions into organized collections — the measurements, the candidates, photos, purchase price, and estimated value. Synced across your devices, exportable any time.
The full record, not just a name
A saved session keeps everything that led to the identification — so six months later you know not just what the stone is, but how you concluded it.
Observations & Conclusion
All entered measurements — RI, SG, fluorescence, optic character — plus the candidate results and your conclusion. Reopen any session in the identifier to continue testing.
Value & Provenance
Purchase price, estimated value, seller information, carat weight, and specimen notes. Your acquisition record lives with the identification record.
Photos
Attach field photos and observation photos to each stone. Client name, examination purpose, and effective date round out the record for professional work.
Import, Export & Sync
Collections sync across devices. Import existing inventories from CSV or JSON with column mapping and validation; export any collection back out, or into a report.
Actual product screens: the Collections tab and a session's valuation record.
Anyone with more stones than memory
Collections turn a drawer of stones into a documented inventory.
Catalog with evidence
Each stone carries its measured properties, photos, and what you paid — a documented record of the collection, organized however you like: by species, by source, by case.
From find to finished
Record material as it comes in — properties, notes, photos — and keep the record as it becomes finished stones. SG works on rough; the record starts before the cut.
A practice logbook
Every practice identification you save builds a personal reference set — which stones you've handled, what you measured, and where you went wrong. Review it before the practical.
