Open GemSnap and aim at your specimen. Natural light works best — no special equipment needed.
Your image is checked for visible clues like colour, texture, lustre, shape, and crystal patterns. Results come back in seconds with confidence and uncertainty clearly shown.
See the likely ID, lookalikes, hardness, crystal system, market context, authenticity red flags, and a clean label for your collection.
