1. Crater of Diamonds State Park, Arkansas
Did you know this is the world’s only public diamond mine where you can dig in the original volcanic source? Over 35,000 diamonds have been found here since the park opened, and every single one was discovered by regular visitors just like you. Some diamonds found here have been worth thousands of dollars.

2. Emerald Hollow Mine, Hiddenite, North Carolina
This mine holds a special title as the only public emerald mine in America where you can prospect and keep your discoveries. Named after the rare mineral hiddenite found here, this spot has attracted gem hunters for generations. The thrill of uncovering a brilliant green emerald makes every shovelful worthwhile.
Beyond emeralds, you might stumble upon aquamarine, sapphire, garnet, amethyst, or topaz. The variety keeps things exciting because you never know what colorful treasure will appear next. Families love visiting because kids and adults can dig together and learn about geology while having fun outdoors.
3. Gem Mountain Sapphire Mine, Philipsburg, Montana
Montana’s reputation for stunning sapphires draws treasure seekers from around the globe to this famous mining site. You can either dig directly in the earth or wash buckets of sapphire gravels to see what sparkles emerge. The process feels like panning for gold but with even more colorful results.
Sapphires come in many shades here, from deep blue to pink, yellow, and even rare green. Many visitors have their finds cut and polished into beautiful jewelry after their trip. The scenic mountain setting makes the experience even more memorable, combining natural beauty with the excitement of discovery.
4. Royal Peacock Opal Mine, Nevada
Fire opals glow with incredible colors, and this remote Nevada mine is one of the best places to find them. The mine only opens during certain seasons, so planning ahead is essential if you want to visit. Its isolated location adds to the adventure, making you feel like a true desert prospector.
These opals display brilliant flashes of red, orange, and yellow that seem to dance with light. Because the mine operates on a limited schedule, it maintains an exclusive feel that serious collectors appreciate. Bring plenty of water and sun protection since the desert environment can be harsh but rewarding.
5. Oceanview Mine, Pala Mountains, California
Tucked into California’s Pala Mountains, this mine has produced some of the world’s finest tourmaline specimens. Visitors dig through tailings, which are piles of discarded rock from previous mining operations. What miners once overlooked might be your next treasure, including pink kunzite and peach-colored morganite.
Tourmaline comes in a rainbow of colors, from watermelon pink and green to deep blue and black. The crystals can be quite large and beautifully formed, making them prized by collectors worldwide. Many people return year after year because each visit brings new possibilities and the mountain scenery never gets old.
6. Spectrum Sunstone Mine, Oregon
Oregon sunstones are unique feldspar crystals containing tiny copper inclusions that create a glittering effect. You can dig directly in the earth or screen through prepared piles of material to find these shimmering gems. When sunlight hits them just right, they sparkle like tiny galaxies captured in stone.
The high desert landscape surrounding the mine offers stunning views while you hunt for treasures. Some sunstones display a phenomenon called schiller, where the copper creates a metallic sheen across the stone’s surface. Whether you find a small chip or a large crystal, each sunstone is a piece of Oregon’s volcanic history.
7. Cherokee Ruby & Sapphire Mine, Franklin, North Carolina
Franklin has earned the nickname “Gem Capital of the World,” and this mine shows you why. Visitors search for rubies, sapphires, and other corundum gem material that formed millions of years ago in these ancient mountains. The excitement builds with every scoop as you wonder if the next stone will be a brilliant red ruby.
Corundum is one of the hardest minerals on Earth, second only to diamond, making these finds especially durable. The mine provides all the equipment you need, so even first-timers can jump right in. Many families make this an annual tradition, creating memories while building their personal gem collections.
8. Crystal Grove Mine, Herkimer, New York
Herkimer diamonds aren’t actually diamonds but rather exceptionally clear quartz crystals with natural double points. Found in the Mohawk Valley, these crystals formed in pockets within ancient dolostone rock over 500 million years ago. Their clarity and natural faceting make them look remarkably diamond-like, hence the nickname.
Breaking open the dark rock to reveal sparkling crystals inside feels like cracking open geodes. Some private mines in the area welcome collectors during specific seasons, offering the chance to extract your own specimens. These crystals are popular for jewelry and metaphysical purposes, making them valuable finds beyond their natural beauty.
9. Mount Mica Mine, Maine
This historic pegmatite mine represents one of North America’s earliest gem mining sites. Mount Mica became famous for producing spectacular tourmaline, including the stunning watermelon variety with pink centers and green edges. Beryl specimens, including aquamarine and golden beryl, also hide within these ancient rocks.
Pegmatite deposits form when molten rock cools slowly underground, allowing large crystals to grow. The mine’s long history means generations of collectors have searched these slopes, yet new treasures still emerge. Maine’s rugged beauty surrounds you while you hunt, making the experience as much about nature as gemstones.
10. Rainbow Ridge Opal Mine, Virgin Valley, Nevada
Virgin Valley produces some of the world’s most spectacular opals, including rare black opals that can be worth small fortunes. The mine opens seasonally, allowing public digging during warmer months when conditions are best. Fire opals from this location display incredible color play, flashing rainbow hues when moved under light.
These opals formed when ancient volcanic ash mixed with water and silica over millions of years. Because they can be fragile, finding one intact requires patience and careful digging. The remote location adds to the adventure, making successful finds feel even more rewarding after the journey.
11. Herkimer Diamond Mines, New York
Several private mines and camps throughout the Herkimer area offer opportunities to dig for these famous quartz crystals. Each location has its own character, but all provide the tools and guidance needed to extract your own sparkling specimens. The crystals hide inside hard rock that must be carefully broken open.
Many visitors describe the satisfying crack of splitting rock to reveal glittering crystals inside as addictive. Some crystals are tiny, while others can be several inches long with incredible clarity. These mines often provide camping facilities, letting you spend multiple days searching and enjoying the beautiful New York countryside.
12. Diamond Hill Gem Mine, South Carolina
South Carolina’s Diamond Hill welcomes families and rockhounds to search for quartz, amethyst, and various semi-precious gems. Despite the name, you won’t find actual diamonds here, but the quartz crystals can be quite impressive. Amethyst’s purple color makes it a favorite find among visitors of all ages.
The mine provides a relaxed atmosphere where you can take your time exploring and learning about local geology. Kids especially enjoy the hands-on experience of sifting through dirt and discovering colorful stones. Many visitors bring home buckets of specimens to display or use in rock tumbling and crafting projects.
13. Graves Mountain, Georgia
While not always operating as a formal tourist mine, Graves Mountain has legendary status among serious rockhounds. The site is known for corundum, which includes both rubies and sapphires, plus beautiful garnets and other minerals. Collecting opportunities depend on current land access rules and special dig events.
When open digs are scheduled, collectors travel from across the country to participate. The mountain’s complex geology creates an incredible variety of minerals in a relatively small area. Always check current regulations and get proper permission before collecting, as rules change based on land ownership and conservation concerns.
14. Glass Buttes, Ochoco National Forest, Oregon
Volcanic activity millions of years ago created this rockhound paradise filled with obsidian, jasper, and agate. Glass Buttes earned its name from the shiny black obsidian that covers much of the area like natural glass. Collecting is allowed in many zones, though you should always verify current federal land regulations.
The variety of colors and patterns in the volcanic glass keeps collectors returning season after season. Rainbow obsidian, mahogany obsidian, and fire obsidian all occur here naturally. The high desert scenery provides breathtaking views while you search, and the area’s remoteness means you might have entire hillsides to yourself.
15. Noble, Oklahoma (Rose Rocks)
Rose rocks represent Oklahoma’s official state rock, formed from barite crystals mixed with red sand that creates petal-like shapes. While not gemstones in the traditional sense, these mineral formations are uniquely beautiful and highly collectible. They formed millions of years ago when this area was covered by an ancient sea.
The crystals naturally arrange themselves to resemble blooming roses, making them popular souvenirs and gifts. Collecting is permitted in designated areas around Noble, though you should always respect private property and ask permission. These geological curiosities prove that not all treasures sparkle—some are beautiful in their own earthy, sculptural way.
