01 / METHOD
How to identify rocks
Upload a sharp photo with the whole specimen in view. Include its origin if you know it. Read the visible evidence alongside the tentative match, then compare it with the rock in your hand.
PHOTO IDENTIFICATION
Rock identification
01 / YOUR SPECIMENSingle photo
Take a closer look.
Choose a clear photo of one rock.
Natural light. Plain background.
JPG, PNG or WebP · One image · Up to 10 MB
When you identify, your photo and notes are sent to Google Gemini for analysis. No history is saved by this site.

TENTATIVE PHOTO MATCH
- Category
- Visible features
- Hardness clues
- Hardness cannot be measured from a photo. A physical test is needed.
- What to check next
The evidence comes first.
Your result will show a tentative name, category, visible features and hardness limitations. If the image is inconclusive, we will say so.
A photo match is a starting point, not a laboratory identification.
02 / SCOPE
What this tool can assess
Photo-based suggestions for rocks and minerals, including igneous, sedimentary and metamorphic material. Coverage and accuracy have not been validated against a reference collection. No species count or complete coverage is claimed.
03 / EVIDENCE
What a photo cannot tell you
Texture, visible grains, layers and apparent color may help narrow a rock ID. Hardness, density and composition require physical examination or testing. Weathered surfaces and lookalikes may prevent identification.
Rock ID questions
Can you identify rocks from a phone photo?
Yes, phone photos can be submitted. Use the rear camera in daylight and avoid blur. A usable photograph does not guarantee a correct match.
Will I get a hardness number?
No. The tool cannot measure hardness from an image and does not invent a Mohs value for your specimen.
Do I need an account?
No account is needed. The identification service is connected and ready to analyze one photo at a time.
How many photos can I submit?
One photo per request, up to 10 MB. Actual service availability depends on the owner's Gemini quota. We do not promise unlimited use.
