Where to Find Quartz Crystals in Arkansas
Arkansas is the only state in the US that produces commercial-grade quartz crystals, and the Ouachita Mountains of west-central Arkansas are one of the premier quartz collecting regions in the world. The crystals form in hydrothermal veins within Ordovician sandstone and shale of the Crystal Mountains. Points range from thumbnail-size to clusters weighing hundreds of pounds.
Top sites:
- Wegner Crystal Mines, Mount Ida — Paid dig site. Multiple claims open to public digging. Tools provided or bring your own. Produces clear points, clusters, and occasional phantom quartz. Sedan access.
- Twin Creek Mine, Mount Ida — Paid dig site with consistent production. Good for families.
- Ron Coleman Mining, Jessieville — Large operation near Hot Springs. Tailings piles available for surface collecting.
Arkansas quartz is prized for water-clarity points and well-formed terminations. Bring a flat-head screwdriver, small chisel, and spray bottle. Dig in the red clay — crystals form in pockets and seams. When you hit a pocket, slow down and switch to hand tools to avoid damage.
Where to Find Diamonds in Arkansas
Crater of Diamonds State Park near Murfreesboro is the only diamond-producing site in the world open to public collecting. The diamonds occur in a lamproite volcanic pipe — one of only a handful in North America. Since the park opened in 1972, visitors have found over 35,000 diamonds, including the 40-carat Uncle Sam (largest diamond ever found in the US).
Top sites:
- Crater of Diamonds State Park, Murfreesboro — 37-acre plowed field over the lamproite pipe. Finders keepers — you keep any diamond you find, regardless of size or value. Entry fee required. Surface searching after rain is the most productive method.
Diamonds here are typically small (under 1 carat) and come in white, brown, and yellow. They have an adamantine (greasy-bright) luster and rounded octahedral shapes. The best strategy: go the day after heavy rain. The park staff plows the field regularly to expose fresh material. Bring a screen classifier and look in the gravel concentrate.
Where to Find Novaculite in Arkansas
Novaculite is a dense, microcrystalline silica rock unique to the Ouachita Mountains. It has been quarried for whetstones (sharpening stones) since the early 1800s — "Arkansas stone" is a trade name known worldwide. The formation is Devonian to Mississippian in age and outcrops extensively in Hot Spring, Garland, and Saline counties.
Top sites:
- Lake Catherine area, Hot Spring County — Novaculite outcrops along road cuts and creek banks. White, gray, and black varieties. Surface collecting on Ouachita National Forest land.
- Crystal Mountain, Montgomery County — Novaculite outcrops adjacent to quartz crystal collecting areas.
Novaculite is a hardness of 7 (same as quartz — it is essentially microcrystalline quartz). It fractures conchoidally like flint and was used by Native Americans for tools and projectile points. The black variety is the most sought-after for knife sharpening. It takes an excellent polish for lapidary use.
Arkansas Rockhounding Laws & Public Land Rules
BLM Land
Arkansas has no BLM land.
National Forests
Collecting is allowed in the Ouachita and Ozark-St. Francis National Forests for personal, non-commercial use. Quartz crystal collecting is permitted with hand tools only — no explosives, no motorized equipment. The Forest Service periodically designates specific areas for crystal collecting.
State Parks
Crater of Diamonds State Park is the only state park where collecting is allowed (diamonds, minerals — finders keepers policy with paid entry). All other Arkansas state parks prohibit collecting.
Collection Limits
National Forest: reasonable quantities for personal use. No specific weight limit published, but commercial-scale collecting requires a permit.
What's Protected
Vertebrate fossils and archaeological artifacts on state and federal land are protected. Native American sites in the Ozarks and Ouachita Mountains are common — do not disturb.
The Mount Ida area (Montgomery County) is the center of Arkansas quartz crystal collecting. Multiple paid dig sites operate year-round. Most private mine operators are welcoming and will teach beginners. Ticks and chiggers are a serious problem in the Ouachita Mountains from April through October — use permethrin-treated clothing.

- Bucket and bags — 5-gallon bucket, zip-lock bags for specimens
- GPS device or phone app — cell service is unreliable at most sites
- 1 gallon of water per person — minimum, more in summer
- Sturdy boots — ankle support for loose talus and mine tailings
- Field guide — a regional mineral identification guide for Arkansas
Always respect private property, follow Leave No Trace principles, and check current regulations before collecting. On BLM land, the general rule is 25 lbs per day plus one specimen for personal, non-commercial use.
