What Makes Herkimer Diamonds So Special?

Herkimer Diamonds aren’t actually diamonds—but they’re just as dazzling. These unique double-terminated quartz crystals are found only in Herkimer County, New York, and are prized for their incredible clarity, natural faceting, and raw beauty. Each crystal forms naturally with 18 facets and sharp terminations, requiring no cutting or polishing to shine.

Unlike other quartz, Herkimer Diamonds formed over 500 million years ago in ancient dolostone under unique geological conditions, giving them their signature brilliance and energy. Because of their age, clarity, and rarity, they’re not just pretty—they’re powerful and often used in jewelry, healing practices, and even scientific research.

Whether you’re a collector, crystal enthusiast, or just love beautiful things from nature, Herkimer Diamonds are truly one-of-a-kind treasures.

What To Know Before You Go

This is real, hands-on fun! Wear comfortable clothes that you don’t mind getting dirty, along with sturdy, closed-toe shoes. Curiosity is a must. Herkimer Mountain is wild and beautiful, so come prepared. Bring insect repellent, or grab some at check-in. We dig rain or shine, so check the forecast and dress accordingly—a little mud only adds to the adventure! Speaking of mud and adventure, you’ll need a 4 wheel or all wheel drive vehicle to access the mine as it can be a muddy rough adventure of a ride!

We recommend booking ahead to ensure a smooth, personalized experience. When you arrive, check in at our cozy, rustic cabin—part gear stop, part general store, and full of heart. It’s where you’ll pick up your equipment, browse fun merchandise, and soak up the excitement before heading out to the dig.

Our friendly team will greet you with a smile, share expert tips, and help you find your perfect spot—whether you’re visiting with your family, your partner, or on your own. This is more than just a dig—it’s a shared adventure. Be kind, stay curious, and breathe in the fresh mountain air. You’re not just uncovering crystals—you’re making memories to treasure.
