Super sparkler! Rhodium plated sterling silver cubic zirconia ring with CZ halo edge. Center CZ measures approximately 9mm. ABOUT RHODIUM FINISH: A rhodium finish is plated over other metals to make it non-tarnish, and is a hard-wearing, scratch resistant metal - the same metal used to plate white gold! Rhodium is more expensive per ounce than gold, platinum, or palladium!
