These tiny Hill Tribe silver heart charms are sure to give your designs a gorgeous touch. 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.
