For your consideration is this lovely circa 1900-1910 sash pin. Unmarked but tested and guaranteed as sterling silver, it has a nice ornate design with a center rays and beautiful floral edging. I took a close up so that you can appreciate the beauty. It has a c closure consistent with the era.
It measures 2 and 1/2 inches by 1 and 3/8 inches.
It is in excellent functioning condition but has a very uneven patina - mostly back.
