What's the best way to take a photo for identification?

For the best results, place your rock on a plain background in bright, natural daylight if possible. Take a clear, close-up photo of the overall specimen. Then, upload extra photos: a close-up of the grain or texture, a picture of a freshly broken surface if available, and try wetting the rock to show its true color. Multiple clear images give the AI the best chance to succeed!

Can it identify every single rock or mineral?

Our AI database is vast and constantly growing, covering a huge range of common and many uncommon rocks. However, geology is incredibly diverse. Very rare, highly weathered, or unusually shaped specimens might be challenging. Using the identification form to provide location and physical properties greatly improves the chances of a correct match, even for tricky samples.
