This ring is the ultimate marriage! Originally the mounting had a chipped stone in it. We bought the ring both to recut the stone and for the mounting. The recut stone sold quickly and we have been looking for the perfect stone for the mounting ever since. One day a lovely lady walked in, explained she had inherited some loose Tanzanites and did not want them. The gorgeous oval Tanzanite shows both blue and purple and was one of those stones! Sometimes you just need to be patient and wait for the perfect stone or setting! Enjoy.
