Frequently Asked Questions

Where can I find crystals near me?

Use our specimen maps to find crystal collecting sites nearest to you. Select the crystal type you want to find from the list above, and the interactive map will show all documented locations with GPS coordinates, access status, and what else has been found at each site.

What is the most common gem to find rockhounding?

Quartz varieties (clear quartz, smoky quartz, amethyst, rose quartz) are the most commonly found gems across our database, followed by agate, jasper, and garnet. These minerals occur in diverse geological settings across most US states.

Can I dig for crystals on public land?

Yes. BLM and National Forest land generally allow casual mineral collecting for personal use. The standard BLM limit is 25 pounds per day plus one specimen. National parks prohibit all collecting. State parks vary — check each state's regulations.

What crystals are worth money?

Gem-quality specimens command the highest prices: benitoite (California), Herkimer diamonds (New York), Oregon sunstones, and Montana sapphires. Even common minerals like amethyst and turquoise have value when found in good quality and size.

How do I identify rocks and minerals I find?

Start with basic tests: hardness (scratch test against known minerals), streak color (rub on unglazed porcelain), luster (metallic vs glassy vs dull), and crystal habit (shape). Our specimen pages include identification tips for each mineral type.
