This is a beautiful Victorian sash pin. The open frame finish is gold tone and does show some discoloration and wear to the finish consistent with age. It has a floral repousse design of lilies of the valley and leaves over a textured background. The focal point is a large faceted deep purple glass stone. There are additional small deep purple pave set stones located throughout the frame. The closure is a thick C clasp soldered to the frame with a thick straight pin stem. This is a heavier piece with moderate patina. Size is 1 3/4 inch in width by 2 1/4 inches. Dates to the late 1800's.
Sash pins were a type of pin used to secure a sash at a lady's hip when the fad of wearing a sash over the shoulder and across the bosom became a popular imitation of Queen Victoria. Most have thick pins stems to allow for penetrating several layers of fabric.
