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.

How to Maximize Your Chances of Finding Herkimer Diamonds

For the best chance of finding Herkimer diamonds, use these expert tips:

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


  2. Use the “Find and Break” Method: The most common method is to break open dolostone rocks using a rock hammer. Focus on areas where you see vugs on the surface​.


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


  4. 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​.


  5. Bring the Right Equipment: A rock hammer, chisel, gloves, and safety goggles are essential. You can rent these tools at most mines, but bringing your own ensures you have what you need​.

  • Long pants and a long-sleeve shirt: These will help protect your skin from flying rock shards while hammering​.
