Explore properties, meanings, chakra associations, care guides, and how to work with your crystal.
Identification that actually works
Most crystal apps use basic image matching on 50 common stones. Crystal Index uses professional-grade AI trained on hundreds of real crystals — including the obscure ones.
30 billion parameter vision AI
Powered by Qwen3-VL-30B — a state-of-the-art vision model that analyses colour, transparency, lustre, crystal habit, and texture the way a gemologist would.
Gets smarter with every identification
CLIP visual learning stores reference embeddings from confirmed identifications. The more people use it, the more accurate it gets — no other crystal app does this.
274+ crystals including rare varieties
Not just Amethyst and Rose Quartz. Melanite, Covellite, Eudialyte, Nuummite — trained on rare and collector-grade stones that other apps have never heard of.
Real collector photos as reference
Reference images come from a real crystal collection, not stock photography. The AI has seen how crystals actually look in someone's hand, not a studio lightbox.
Lookalikes and key differences
Identification includes the most likely matches ranked by confidence, plus the crystals it could be confused with — so you can rule things out as well as in.
