Crystal helps you instantly identify rocks, crystals, gemstones, and minerals from a photo. Just snap or upload an image to get accurate AI-powered matches, geological facts, physical properties, rarity insights, and detailed information about the stones you discover.

Hey 👋 I’m Hakim, an indie developer, and I built Crystal to make discovering rocks, crystals, gemstones, and minerals feel instant and accessible. I’ve always found it frustrating when spotting an interesting stone outdoors, in jewelry, or while traveling, and never really knowing what it was. Most tools felt outdated, complicated, or too focused on experts. So I wanted to build something simple: take a photo → instantly identify the stone → learn its story. With Crystal, you can: • Identify rocks, crystals, gemstones, and minerals in seconds • Learn geological facts and physical/chemical properties • Discover rarity and useful details about each stone • Build curiosity about the natural world around you Would genuinely love your feedback, ideas, or feature requests 🙏

@hakim98 which data source are you using for evaluation? How accurate is your AI?

@chrismessina Great question. Crystal uses AI vision to analyze the photo and compare visible features like color, texture, shape, transparency, and patterns with geological/mineral knowledge.

Accuracy depends a lot on photo quality and the stone itself, since some minerals can look very similar from a photo alone. So I’d position it as an AI-assisted identification tool, not a lab-grade certification. For valuable stones, I’d still recommend confirming with a gemologist or lab test.
