Herkimer diamonds are not actually diamonds, but double-terminated quartz crystals that are known for their exceptional clarity and natural facets. Found primarily in Herkimer County, New York, these crystals have become a popular draw for gem enthusiasts and rockhounds alike. Whether you’re planning a weekend getaway or a dedicated mining trip, here’s everything you need to know about mining Herkimer diamonds.
What Are Herkimer Diamonds?
Herkimer diamonds are double-terminated quartz crystals, unique for their natural points on both ends. These crystals are found in exposed dolostone in New York and are highly sought after for their clarity and brilliance.
Unlike other quartz crystals, Herkimer diamonds don’t need to be cut or polished to exhibit their sparkle, making them prized by both collectors and spiritual practitioners for their natural beauty.

Choose the Right Rocks: Look for porous or cracked rocks with visible cavities (vugs) where Herkimer diamonds may have formed.

Scavenger Prospecting: For beginners or those with children, scavenging the quarry floor for loose crystals can also yield good results.

Visit in Spring or Fall: The mines can get busy during the summer, so consider visiting during the off-season for better access to prime mining spots.
