Our Beach Treasures Seashell Bracelet -- bearing our signature stamp, BT☆Sterling® -- is a one of a kind creation made from treasures discovered along the beaches of Outer Banks. Each piece of beach glass and shell is encased in 9.25 sterling silver for a bracelet that adjusts from 7 and 1/2 to 8 and 1/2 inches (thanks to its toggle closure) and measures approximately 1 and 1/8 inches wide.
