Herkimer Diamonds are double terminated quartz that are found in Herkimer, NY as well as other places in the US. Double terminated means that the quartz crystal comes to a point at each end. Each herkimer diamond has 18 facets which helps to create a beautiful luster. Since each herkimer diamond is found naturally no two will ever be the same which allows for a truly unique piece. This ring comes in the hammered texture only. ___________________________________________________________________________ 14K Gold Filled / 14K Rose Gold Filled Wire ♥ Prong setting created out of coordinating 20g wire ♥ 4-6mm Herkimer Diamond Quartz Crystal (some may have black inclusions as this as a natural occurrence in nature) ♥ No two herkimer crystals are the same
