This vintage ring features a stunning iridescent opal cabochon set in 14K yellow gold. The solitaire setting showcases the beauty of the unique opal stone, making it a striking statement piece for any jewelry collection. With a ring size of 5, this piece is a versatile and elegant choice for any occasion. I tested this ring with a test kit, and it came back as 14 karat, not sure of the origins of the opal.
