Hello, I don't make it a habit to be busy in someone's auction, but felt I needed to make a suggestion here, as I am fully informed about Moonstones, aside from owning many brilliant pieces and having a passion for them, I think what you have here is a, "Garnet Rainbow Andradite", which is a stunning piece of jewelry. You can find information on it at "gemology online.com". Please forgive me if I've stepped out of bounds; I assure you it is not my intent to hurt your feelings or under-mind you.
You are welcome! Whew! Thank you for being so wonderful; I appreciate you! It is a magnificent beauty! As soon as I regenerate some coinage!!! F/W/B!!!
