This sterling silver pin/pendant is a show piece! It has a delightful modernist shape that is impressive as a pin but can also be slipped on a chain and worn as a pendant. I love dual purpose jewelry! Pin is about 2 5/8" across and 2 3/8" top to bottom. It is marked Mexico and has a maker's mark also. I have paired this piece with a sterling chain from Italy which has little beads along each side and is just under 24" long. Together they weigh about 28 grams. Both pieces are in excellent condition with old patina which can be removed with a little silver polish if you so desire.
