Very gently used as shown in the photos. Beautiful oval faceted London blue topaz mounted in shiny sterling silver. This blue topaz stone measures 6/16” (a smidge over 1/2”) in length and 1/2” in width at its widest. There are clear accent stones on both sides of the topaz of unknown type. This beauty is a ring size 5. Sterling hallmark is shown in photo. Lucky you, size 5
