Cross Necklace

I’m not sure what this is made of as I do not test anything. It looks like it could be signed but it’s hard to make out. Then again, it could not be. I’m not sure. There’s no visible signs of wear. None that I can see. Silver with brownish purple stones. It’s very pretty. Necklace is approximately 18 inches. Cross is approximately 2 inches. Needs to be cleaned. I haven’t even wiped it off. Please see photos as they are part of the description. Ships as soon as payment is received. All offers welcome! Thanks for looking!
