Herkimer diamond and hematite bar necklace with oxidized sterling silver cable chain. According to Wikipedia, Herkimer diamonds are not actually diamonds, but double-terminated quartz crystals. The “diamond” in their name is due to both their clarity and natural faceting - crystals possess double termination points and 18 total facets. A tiny faceted hematite bead is on either end of the Herkimer diamonds. This is a great neutral piece that is striking on it's own and will add a unique layer when paired with your favorite necklaces.
