Rare cocktail ring by Angelique de Paris. Not sure of the materials, but the brand uses high end materials in their jewelry. I do not have size information, but it fits my size 7-1/2 middle finger or a little loose on my size 6 ring finger. Excellent condition, but there is some discoloration on the metal on the inside of the ring. This listing is for the ring only. Not the earrings shown in the last photo.
