RockLens: Rock Identifier

Identify rocks, crystals, gems, and minerals from a photo.

RockLens shows three likely matches instead of pretending every photo has one certain answer. Compare properties, learn what separates similar specimens, and use simple home tests to confirm your find.

WHAT YOU CAN DO

• Scan one to three photos of a rock, crystal, gem, or mineral • Compare three candidate IDs with clear confidence tiers • Follow practical streak, scratch, and magnet test guidance • Explore typical retail market ranges and the factors that affect them • Save photos, notes, tags, and optional location details in your field journal • Queue a scan while offline and send it when your connection returns • Export your collection when you need it

TRY IT FIRST

Your first three complete scans are free. Your collection journal remains available without a subscription. Optional Premium plans unlock up to 50 scans per day and advanced features; current prices and terms appear before purchase.

PRIVATE BY DESIGN

No RockLens account is required. Your journal stays on your device. Photos selected for identification are sent securely for processing. Location is optional. With your consent, RockLens may send an approximate area with scan photos to improve identification; saved precise coordinates remain on your device.

Market ranges are educational context for ordinary examples, not an appraisal or valuation of your specimen. Identification results should be confirmed before making safety, purchase, or sale decisions.
