Herkimer diamonds are unique quartz crystals with which Melissa has designed a small limited edition group. From Herkimer, New York, these crystals resemble diamonds because of their double matrix formations (but are a lot cheaper!) A limited edition treasure awaits with these Herkimer diamond drop earrings. The quartz crystals are hugged by a 14 karat gold prong setting that drops perfectly from the earwire. Hangs approximately 11mm from the ear with a 5 x 7mm stone.
