Nice costume ring with quality pink stone

This beautiful ring will just knock your socks off. No markings of any kind, so not sure if it is electro plated, chrome, rhodium or what. The stone is stuning and is finely faceted to catch and reflect prismatic colors from light. Stone measures 5/8" in diameter and is prong set. Ring is a size 10 and is flawless. I just don't know a thing about it, except it is magnificent!!
