Vintage sterling silver ring with raised rib design. It is set with denim blue lapis lazuli that has a beveled cut. The ring has a little bit of verdigris where the square setting is soldered into the ring. (Solder has copper and causes verdigris with age).

Size 9 face is 1/2” wide. No hallmarks. I acid tested this ring and it is sterling silver. Weight: 10.4 grams.
