Gold COACH earrings, approximately 2.5cm in size, with a jewelry care guide. - Brand: COACH - Color: Gold - Size: Approximately 2.5cm - Accessories: Box, Jewelry Care Guide Thank you for viewing. Earring Shape: Hook/Chain Accessories: Box, Booklet Color: Gold系 (Gold-toned) I don't know what the material is. They are from about 10 years ago, and the subtly engraved logo is cute, without being too flashy. It's a design you don't see very often. There are scratches on the surface if you look closely.
