Here's a budget-friendly jewelry set with so much potential. Two 18kt yellow gold over sterling silver rings seamlessly stack together -- the top style twinkling with a 1.90 carat round brilliant-cut CZ center, as 2.10 ct. t.w. round brilliant-cut CZs decorate the rest of the engagement and wedding band duo. Wear them as such, or separately to extend their versatility. 1/2" wide. CZ ring set. CZ weights are diamond equivalents.
