Nice pin with five large smoky quartz stones in a swirl of gilt metal. This pin is marked silver, which means it is probably not sterling, but a lesser grade of silver with gold-plate (wash) over it. This pin is tarnished to a brassy tone, but the stones are beautiful, and they blend beautifully with the metal. Locking clasp keeps it secure. Generously-sized at 2" x 1 1/2".
