Gold Over Sterling Silver CZ Ring Size 7

Nicely made gold over sterling silver ring with kind of a checkered look of cz accents. The ring was catching shadows in the pictures. There are no black spots. It just has a wavy design… it’s really an excellent condition no fading to the color. The stones are not dull. Marked 925 CZ and what appears to be a makers mark, but I cannot make it out. The other side is stamped China. It is a size 7.
