A totally unnecessary hair ornament, and perhaps for that reason, something desirable. We assume this was custom made to the original owner's specifications because the workmanship is so beautiful and the mint green tourmalines so well matched. The row of teeth at the interior of the barrette (see images 4,5, and 8) secure the wearer's hair, and the row of tiny diamonds completely surrounding the tourmalines add to the brightness. It measures 3 inches in length by 1/2 inches in width. Although specifically constructed as a hair ornament, it can be adapted to a brooch by a skilled jeweler.
