Herkimer Diamond wholesale for jewelry making

Herkimer Diamond beads and cabochons

Herkimer Diamond is a distinctive variety of quartz found exclusively in the Herkimer region of New York, USA. These naturally occurring crystals are known for their unique double-terminated shape, with points at both ends. Despite their name, Herkimer Diamonds are not actual diamonds, but a special form of naturally crystallized quartz.

Similar double-terminated quartz crystals can also be found in mines in Afghanistan and Pakistan. However, these are not technically Herkimer Diamonds. We exclusively offer genuine Herkimer Diamonds mined in Herkimer County, New York, with a selection focused on AAA-grade specimens.

Our collection includes a variety of genuine Herkimer Diamonds in different forms, including natural rough crystals, beads, faceted and unfaceted stones, and pendant tops.
