Rock identification FAQ

Can a rock be identified from a photo alone?

Often it can be narrowed down, but hardness, streak, magnetism, or an acid test may be needed for a stronger identification.

What photos should I upload?

Use a dry, freshly broken surface in natural light. Include a close-up and a wider view with a size reference.

Does this estimate value?

No. Identification and monetary appraisal are different tasks; valuable specimens should be examined by a qualified professional.
