Pince Nez (French for Pinch Nose) or folding eye glass reads 14K SPG with beautiful engraving. The glasses appear more ornamental than really for sight. They are very ornamental, they are very ornate on the bridge. The glasses can be folded over and across each other, held by an ornamental clasp. To release you depress the clasp and the glasses can be brought across. The glasses are 3 7/8 across the bridge and 2 inches wide. The Pince Nez was designed to ride on the top of the nostril ( to give that haughty air) Very clever glasses and the chain with it I think is sterling and makes a lovely pair. They will come in a velvet bag and in a gift box. Could use a little cleaning. For you from Kansas!
