I do love Tanzanites. The purple/ blue color is so pretty. This fine ring has a round Tanzanite stone. The band is hallmarked 18K white gold and the makers initials VJ. There are tiny Diamonds around the Tanzanite, and on each shoulder. I count 10 Diamonds on the shoulders, and 23 Diamonds around the Tanzanite. The ring is a bit over size 7. Weight is 3.9 grms. Condition is excellent. I would date this fine ring at c1980's-2000.
