These lovely Quartz Crystal hoops are made of either 14k Gold Fill or solid 935 Silver. I hammer the metal on both planes to give it strength and texture. These are a great everyday piece that will go with anything! Please note, the origin of these stones is Pakistan not NY. ● Handcrafted in Woodland Park, CO ● Stone: 5-8mm Quartz Crystal ● Hoop diameter: 1"-1 1/8" ● Metal: Solid 935 Silver or 14K Gold Filled ● Nickel and Lead free ............................................................................ -About the stone- Double terminated 18 faceted quartz crystals were found in Herkimer NY in the 18th century and because of their clean natural facets and high clarity they were given the name "Herkimer Diamonds". Now similar beautiful 18 faceted crystals have been found in many places around the world (we believe our stones come from Pakistan). Technically only the stones found in a certain regain of NY can properly bear the name "Herkimer Diamond"
