Every rock, mineral, gem, and fossil you have, and where you found it.
Rockhound keeps your collection in one place: each specimen's photos, what it is, where it came from and who found it, its size and what it's like, and what it's worth. It keeps your collecting sites and field trips, the checklists you're working through, and what you want and have to trade, and it lets you show off your collection with a link.

🔷 Every detail, filled in
Type a name and the dictionary of 1,043 minerals, gems, rocks, and fossils fills in its formula, hardness, streak, lustre, and crystal system. Add its locality, size, weight or carats, fluorescence, and photos under white and UV light.
🥾 Sites and field trips
Keep the places you collect, with their GPS, directions, and access notes encrypted. Plan a trip with a packing list, add your finds straight from it, and see everything a site has given you.
✅ Checklists and wants
The Mohs scale, rock types, the quartz family, birthstones, fossils through time, or every zeolite in the dictionary: fill each spot from your specimens, and put what's missing on your want list for the next show.
🖼️ Galleries and trading
Share your collection, or a trade list, with a link or a QR code on your show table. You choose how much of each locality to show; visitors can message you without seeing your email.
🏷️ Labels and safety
Print classic specimen labels with catalogue numbers and QR codes. Radioactive, toxic, and fragile specimens are flagged, with how to keep and handle them.
🔐 Private, and yours
Share the whole collection with family or a club friend, to look or to help keep it. Exact spots, where specimens are kept, and every photo and paper are encrypted. Reports for insurance, a theft, and an estate.
Values are your own estimates, and the dictionary's figures are typical ones: specimens vary. Rockhound isn't an appraisal, or legal advice about where you may collect: check each place's rules, and ask permission on private land.
