Identify crystals from light and structure.

Photograph the specimen under neutral light, then show its crystal habit, luster, cleavage, matrix, and scale. With Gemr, you can compare the likely material and visible evidence. Treat the candidate as a starting point and compare the visible evidence before you rely on the name.

You can download Gemr for free. The current App Store description says you need a paid subscription to use its features. Check the listing for current plans before you subscribe.

Photograph the specimen without filters and include a neutral reference when color matters. Show habit, faces, luster, cleavage, inclusions, matrix, and scale from several angles. Save the source and notes, then ask specialists to handle authenticity, treatment, and value. Keep the original photographs so you can compare the likely candidate with a trusted regional source or qualified expert.

You won’t find a verified universal accuracy percentage in the current App Store listing. Your framing, lighting, visible details, and location can change the result. Use confidence to judge uncertainty, then compare the visible evidence yourself.

No. Use Gemr to organize a likely identification and its visible evidence. Ask a qualified specialist or current market source to handle authentication, professional grading, appraisal, provenance, and sale price.
