These oval disc beads are the best. Their flat and wavy silver surface is designed for maximum reflection. It is easy to imagine them in a wonderful jewelry design, even as the featured element. These Thai beads and pendants are made by the Karen Hill Tribe in northern Thailand using traditional tribal methods passed down from generation to generation. Purchasing these Thai beads helps sustain a traditional craft and provides the Karen people with a reliable source of income. The silver content in our Hill Tribes silver beads and pendants is typically 95-99%, even higher than sterling (92.5%). This higher silver content is softer and therefore easier to shape into all the unique and wonderful styles. On close inspection you will notice that no two pieces are exactly alike, attesting to the handmade nature of these beautiful pieces.
