These earrings are part of Silver + Salt's Glacier Collection - inspired by the iceburg lagoon and glaciers of Iceland. A one-of-a-kind herkimer diamond is set in a 22k gold bezel with an oxidized sterling silver or shiny sterling silver backing. A raw gemstone that is neither cut nor polished, each herkimer diamond is unique. (Herkimer diamonds are not actually diamonds but a clear quartz. Small black inclusions are normal for this raw stone). The setting are handmade to fit each stone.
