This is a gorgeous ring! The center white Australian opal is a nice 8x6mm oval stone that has a double halo consisting of 18 beautiful 1.75mm round rhodolite garnets and then another halo of 18 1.75mm round moissanite stones that glimmer and shine like diamonds. The ring is solid sterling silver with platinum plating to protect and hamper tarnish. It is a size 8 and is stamped 925 and signed. You will absolutely love this ring!
