VTG Gold and Cubic Zirconia Cluster Ring Size 8

This ring sparkles! The 17 cubic zirconia are brilliant. The band has at least four separate marks, only one of which--the CZ--I can make out clearly. I think the others indicate maker and electroplate. The ring appears to be gold plated showing slight wear on one spot on the bottom of the band. The band also responds to a N52 magnet with slight pull. Definitely not solid gold or sterling silver. But so pretty!
