This is a lovely ring, not hallmarked except for the letter B. The metal tested for sterling. The purple stone is natural, tinged with blue. I do not know what the stone is, perhaps Sugilite. The stone measures 7/8″ X 3/8″. Condition is excellent. The band in the back shows a previous sizing line. The ring is size 6 1/2. Weight is 4.6grms. I would date this pretty ring at c1960′s.
