Handmade Herkimer diamond and sterling silver earrings.
Herkimer diamonds are not actually diamonds, but double-terminated quartz crystals discovered within exposed outcrops of dolomitein and around Herkimer County, New York and the Mohawk River Valley. The “diamond” in their name is due to both their clarity and natural faceting – crystals possess double termination points and 18 total faces (six on each point, six around the center). Geologists discovered exposed dolomite in Herkimer County outcroppings and began mining there, leading to the “Herkimer diamond” moniker. Double-point quartz crystals may be found in sites around the world, but only those mined in Herkimer County can be given this name.
