Any Rock Identifier

Any Rock Identifier helps you identify rocks, crystals, gemstones, minerals, and fossils from a photo. Upload a clear, well-lit close-up against a plain background to get an instant AI identification plus an honest confidence score. If your specimen is ambiguous, it shows uncertainty and can suggest alternatives rather than forcing a single answer.

To make results usable, each identification includes simple at-home field tests you can run to verify the properties behind the match—such as the streak test, Mohs hardness, and magnetism. Depending on the specimen, an acid fizz test may also be suggested as part of confirmation.

Your identifications connect to a curated field guide with 134 stones, including real photos, look-alikes (for example pyrite vs gold and jade vs aventurine), and practical how-to guides focused on key distinguishing features like streak and hardness. Start free with your first 3 identifications, and switch to Pro when you want more daily IDs plus added tools like value & rarity estimates, authenticity checks, care guides, and a downloadable report.

What should my photo look like for the best identification?

Use a clear, well-lit close-up of your specimen against a plain background. If possible, fill the frame so key features like texture, luster, and crystal shape are easy to see.

How does the “honest confidence score” work?

The confidence score tells you how sure the AI is about the match. When the specimen isn’t clear, the tool lowers confidence and may list alternative possibilities.

Can I confirm an identification myself?

Yes. Each result includes simple at-home field tests such as the streak test, Mohs hardness, and magnetism. These tests help verify the properties behind the suggested identification.

What kinds of specimens can I identify?

You can identify rocks, crystals, gemstones, minerals, and fossils from a photo. For safety, identification avoids categories where a wrong answer could be dangerous.

Is the identification guaranteed to be correct?

No. AI suggestions can be wrong, especially for look-alike materials. Always confirm using the included diagnostic tests or consult a qualified expert when accuracy matters.

Is there a free way to try it before upgrading?

Yes—your first 3 identifications are free. Pro adds more identifications per day plus additional features like value & rarity estimates, authenticity checks, care guides, and a downloadable report.
