Geo-Gem — AI Rock Identification & Collector Community
Geo-Gem is the AI-powered rock and mineral identification community. Snap a photo and our AI tells you what you found, then map it, share it, and connect with collectors near you.
AI-Powered Rock & Mineral Identification
Sign in with a free account to upload a specimen photo. AI suggests a possible identification and properties with a confidence score. Confidence is not measured correctness; verify important finds with field references.
Community Discoveries & Interactive Map
Browse public rock and mineral finds shared by collectors. Contributors choose no public location, an approximate area, or a consented precise point. Only finds with a shared location appear on the map.
Regional Field Guide & Rock Database
Our field guide covers rockhounding regions across North America and beyond, with checklists of what to look for, where to search, and how to identify specimens in the field. The rock database includes hundreds of minerals, igneous, sedimentary, and metamorphic rocks with photos and identification tips.
Marketplace & Groups
Buy, sell, and trade rock and mineral specimens through our free collector marketplace. Join local rockhound groups, attend geology field trips and mineral shows, and build your reputation in the community.
