Our Beach Treasures Green Seaglass Bracelet -- bearing our signature stamp, BT☆Sterling® -- is a chunky treasure made from glass discovered along the beaches of Outer Banks. Each piece is encased in 9.25 sterling silver for a bracelet that adjusts from 6 to 7 and 1/2 inches (thanks to its toggle closure) and measures approximately 1 and 1/2 inches wide.
