After all, there’s nothing more enjoyable than stumbling upon a quirky roadside attraction and deciding to take the next exit for a closer inspection.

Thinking back, I can list several unforgettable roadside attractions from my childhood to adulthood: a petrified forest in Arkansas, a museum dedicated to the Donner Party in California, and an antique shop in Upstate New York.

Being a bit flexible during road trips leads us to America’s most unusual side quests, adding some zest to the journey—and providing a break from long hours of driving.

However, there’s one roadside attraction I deeply regret not visiting: the Cherokee Ruby & Sapphire Mine in North Carolina. I drove past it during a road trip through the Blue Ridge Mountains, and it’s been on my mind ever since.

You might have seen similar offers across the United States and wondered if they were genuine and worth your time.

While many urban dwellers may not know, the country is sprinkled with DIY mines where you can search for your own gems. These places offer some of the greatest activities for road trips.

If you’re near a mine, I recommend planning your journey around this unique side adventure. If not, consider taking a detour to one of the locations listed below. As I mentioned, mining for gems is an unbeatable road trip activity.

Especially if you know where to find a well-reviewed mine.

I’ve compiled a list of some of the best places in the US where you can mine for gems, featuring expert recommendations from Donald Clark, a CSM or Certified Supreme Master Gemcutter and member of the International Gem Society.

The big question—will you actually find gems at these mines?

Those who are fortunate and persistent might discover hidden treasures in the mines mentioned below. However, many of these sites are situated on older mines that have seen better days, meaning that finds are not guaranteed. It’s best to view these trips as fun family outings—or simply a great way to stretch your legs after being in the car for too long. But don’t lose hope! Keep your eyes sharp while exploring gem-friendly creeks across the nation!

Here’s where you can mine for gems in the US

Emerald Hollow Mine (Hiddenite, NC)

This 69-acre mine is the only public emerald mine in the world. It’s nestled in North Carolina’s Brushy Mountains, where staff assist you in finding a digging area, or a creek perfect for sifting. While discovering emeralds at Emerald Hollow Mine is rare, they have been found here—along with rubies.

Gem Mountain (Spruce Pine, NC)

Whether you prefer a relaxed vibe or want to delve into an active mine, Gem Mountain offers the perfect DIY mining experience. Casual visitors can explore the main site, sifting through the flume for quartz and garnets. For those seeking adventure, you can pay extra for a four-hour gem-hunting excursion in the mine.

Cherokee Ruby & Sapphire Mine (Franklin, NC)

This is the mine that ignited my fascination when I regrettably drove past the sign and continued westward. Don’t repeat my error—if you’re traveling through Franklin, be sure to plan a visit. First, it’s an excellent way to explore the Smoky Mountains outside of the usual trails. Second, the staff is incredibly enthusiastic and knowledgeable, so you’ll gain valuable insights. Finally, you may just stumble upon a ruby or sapphire.

Gem Mountain Sapphire Mine (Philipsburg, MT)

Get ready to roll up your sleeves—it’s time to sift through gravel in search of sapphires. This operation is quite professional, teaching you about gravel washing, heat treating, and even gem faceting. You may even find an ancient fossil among your discoveries. *Philipsburg is near Yellowstone and Glacier National Parks, making it a fantastic day trip when visiting the area.

Montana Blue Jewel Mine (Helena, MT)

Seasonally open, it’s wise to call ahead to confirm if the Blue Jewel Mine is welcoming visitors. If it is, head there without delay—this is one of the top-rated venues for gem mining in the US. With a bit of patience, you’re likely to discover a sapphire here, as it’s not an overmined location.

Rainbow Ridge Opal Mine (Denio, NV)

While opal may not be as renowned as ruby or sapphire, finding one of these vibrant gems is a dream for any gem enthusiast. Like the Blue Jewel Mine, this site hasn’t been overexploited, leading to a great chance of unearthing a sizable opal.

Crystal Grove Diamond Mine (Saint Johnsville, NY)

This Herkimer diamond mine and campsite offers a fantastic getaway for families. The grounds are beautiful, featuring mature forest and a winding creek. Plus, you can hunt for local Herkimer diamonds (a type of pure quartz), which are unique to this region.
