Unique, Gorgerous, Moonstone Antique Ring Sz 5. Gold plated over 925 Sterling Silver. Large stone 3/4 inch! Estate jewelry. This elegant women's ring features a stunning white stone set in a beautifully crafted gold band. As you can tell, the white strip in the stone moves depending on lighting. (CHATOYANCY is an optical effect where a single, bright band of light appears to move across the surface of a gemstone). The silvery-white sheen across the surface is called adularescence, typical of moonstone. I honestly think that you would not be able to find another ring like this EVER!
