The Best Rockhounding Sites in Arkansas
The only public diamond mine in the world — a plowed volcanic pipe where visitors keep everything they find, diamonds included. Documented for diamond, amethyst, garnet, jasper, and agate. Multi-carat stones still turn up every year; hunt after rain, when fresh diamonds glint on the washed furrows.
The Quartz Crystal Capital of the World. The sandstone ridges around Mount Ida produce the water-clear rock crystal that made Arkansas quartz the world standard — documented here in veins, roadside float, and mine dumps across Montgomery County. The fee mines nearby put you on fresh-dug vein material.
The biggest fee dig in the quartz belt, documented for quartz, amethyst, and smoky quartz. You hunt freshly turned mine-run from an operation that has produced museum-grade clusters for decades — the reliable answer for guaranteed crystals with kids in tow, minutes north of Hot Springs.
The Phantom Mine at Wegner’s is documented for quartz, smoky quartz, amethyst, and calcite — including the phantom-included crystals the mine is named for. Dig the stockpile or pay for vein digging in the mountain itself; either way you leave with Arkansas crystal.
The public window into Magnet Cove — a square mile of igneous rock so strange it holds over a hundred mineral species. The Cove Creek exposures are documented for monticellite, perovskite, kimseyite, apatite, and magnetite, with eudialyte and nepheline syenite in the famous boulder nearby. Micro-mineral heaven.
The old northern Arkansas zinc camps, documented for smithsonite, calcite, quartz, dolomite, and rare greenockite on the dumps. Ozark hill country where turkey-fat smithsonite was once ore and is now the prize. Mind the workings themselves — collect the dumps, not the adits.
Arkansas wavellite is the best in the world — radiating lime-green hemispheres that break into perfect starbursts — and this documented locality carries variscite alongside it. Split the quarry rock along fractures and watch for the green sprays. Two more documented wavellite sites sit nearby on the map.
Rockhounding Regions of Arkansas
| Region | Top sites | What you'll find |
|---|---|---|
| Ouachita quartz belt (Mount Ida–Hot Springs) | Mount Ida, Wegner Crystal Mines, Ron Coleman Mining, Sweet Surrender | Water-clear rock crystal — among the finest on earth — with smoky quartz, amethyst, and calcite from the fee mines and roadside exposures |
| Crater of Diamonds (Murfreesboro) | The Prairie Creek volcanic pipe | Real diamonds — white, brown, and yellow — plus amethyst, garnet, jasper, and agate in the plowed volcanic soil |
| Magnet Cove | Cove Creek Bridge, the Magnet Cove roadcuts | One of the rarest mineral suites in America: monticellite, perovskite, eudialyte, kimseyite, melanite garnet, sphene, and nepheline from an ancient volcanic pipe |
| Wavellite country (Ouachitas) | Three documented wavellite localities | Radiating lime-green wavellite — Arkansas’s signature collector mineral — with variscite in the quarry exposures |
| Northern Ozarks zinc district | The abandoned mines around Yellville | Smithsonite, galena, sphalerite, and rare greenockite on the dumps of the old zinc camps |

Best Time for Crystal Hunting in Arkansas
Diamond hunting at the Crater peaks after rain — the park plows the field regularly, and a hard storm washes the soil and leaves fresh diamonds sitting on the surface. Cool-season hunting beats summer: the field is shadeless, and July surface temperatures are brutal. The biggest finds historically follow deep plowing plus heavy rain.
The quartz-belt fee mines dig year-round, and fresh mine-run beats weathered dumps in any season. Fall through spring is the comfortable window in the Ouachitas — ticks and chiggers are a serious problem April through October, so treat clothing with permethrin if you hunt the warm months.
Roadcut and dump collecting at Magnet Cove, the wavellite quarries, and Yellville is best in winter and early spring: vegetation is down, freeze-thaw has loosened fresh rock, and the snakes are denned up. After any quarry blast or road work in the Cove, the first collector there does best.
Check current weather and road conditions before heading out, especially for remote BLM and Forest Service roads.
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.

Where can you dig quartz crystals in Arkansas?
The Ouachita quartz belt from Mount Ida to Hot Springs — the source of the finest rock crystal in the world. Fee mines like Ron Coleman, Wegner, and Sweet Surrender put you on fresh vein material and let you keep everything; Mount Ida itself is documented for quartz in roadside exposures across Montgomery County. Filter the map above by quartz to see the whole belt, fee and free.
Can you really find diamonds in Arkansas?
Yes — Crater of Diamonds State Park near Murfreesboro is the only public diamond mine on earth, and visitors keep what they find. The plowed field over the Prairie Creek volcanic pipe is documented for diamond along with amethyst, garnet, jasper, and agate. Hundreds of diamonds are registered every year, including multi-carat stones. Go after rain, walk slow, and look for round, oily-lustered pebbles.
Where can you rockhound in Arkansas for free?
The free ground is real: the Magnet Cove roadcuts at Cove Creek Bridge are documented for some of the rarest minerals in America, three documented wavellite localities produce the state’s signature green starbursts, the Yellville-area dumps carry smithsonite and galena, and Mount Ida’s roadside exposures shed quartz. The Crater and the crystal mines charge; the map above separates fee from free by access type.
What gemstones are found in Arkansas?
Diamond is the headline — the state gem, dug by the public at the Crater. Behind it: world-standard quartz crystal (the state mineral) with amethyst and smoky quartz through the Ouachita belt, wavellite and variscite in the quarries, turkey-fat smithsonite in the Ozark zinc camps, and agate, jasper, and garnet in the Crater’s volcanic soil.
