Gila and Grace Nakai have had a shop since 1973. They never disappoint, especially that they remove the copper molicules near the surface so their pieces stay bright longer that other pieces. They always use semi precious gems. And their rings are usually adjustable. This ring is currently a size 7 1/2. The face is 1" tall and 3/4" wide. The weight is 13 grams. Marked Nakai and sterling. Excellent vintage condition.
