Thai sterling silver is 99.5% pure sterling whereas other sterling including bali is 92.5. The other noticeable difference is that thai silver is hand stamped with the tiniest details, and bali silver is created with raised balls, ropes and other intricate designs. These earrings are show stoppers and easy to wear with everything! These beads are handmade in the phillipines and are abstract mother of pearl, wood and finished in sterling wrap. The beads are finished on both sides. I love these earrings!
