Help identify vintage moonstone necklace

[trwier_89]

I am a thrifter and resaler. I can normally identify most any jewelry but I am a bit stumped on this one. I bought it for 4.99$ at my local thrift store. I believe it to be vintage and it is definitely high quality. There are no markings and I don’t believe there ever were.

Your right it is a stunning piece however...you are in active auction with multiple bids ( congrats to you) let the new owner do the research and don't have any regrets.  I suspect one of your bidders already knows!

     Nice find btw, Silver

Yes I am definitely enjoying the live auction, very exciting. I guess I was just curious because I do this quite a bit and knowledge to me equals $. I appreciate you taking the time to write.
