What rockhounds mean by crystals
A crystal is a mineral that has grown with flat faces and sharp edges, reflecting its orderly internal structure. Crystals need open space to grow, so they form in cavities, veins, geodes and pegmatites. The crystals most often collected in the United States are quartz (including amethyst and smoky quartz), calcite, selenite gypsum, fluorite, topaz, garnet, tourmaline and pyrite.

Where to dig for crystals
- Arkansas: clear quartz at fee mines around Mount Ida and Hot Springs.
- New York: Herkimer “diamonds” (double-terminated quartz) at fee mines near Herkimer.
- Oklahoma: hourglass selenite crystals at the Great Salt Plains, in a designated digging area during the season.
- Utah: topaz at Topaz Mountain on BLM land.
- Colorado: smoky quartz and amazonite in Pikes Peak granite pegmatites, much of it under claims.
- North Carolina, Maine and California: pegmatite crystals such as tourmaline, beryl and garnet at fee mines.
How to find crystals
Look for cavities in rock, quartz veins and pegmatites, or for crystals that have weathered loose into clay and gravel below an outcrop. In red clay, screen the soil; in rock, split along cavities carefully. Wrap each crystal straight away.
Rules for collecting crystals
Fee mines are the most reliable legal option. On BLM land, reasonable amounts for personal use are allowed; on national forest land, small amounts, though some crystal areas need permits. Mining claims cover many productive pegmatites, and state and national parks do not allow collecting.
Questions
Where can I dig for crystals near me?
Fee mines are the easiest option: quartz in Arkansas, Herkimer diamonds in New York, selenite at Oklahoma’s Great Salt Plains and topaz on BLM land at Topaz Mountain, Utah. Our city pages list crystal sites near major cities.
Can I keep crystals I find on public land?
Yes, in reasonable amounts for personal use on most BLM land and small amounts in many national forests, but not in national or most state parks, and not on mining claims without permission.
What the map statuses mean is explained in how map statuses work; collecting rules for each kind of land are in rules by land type.
