CZ is an acronym for cubic zirconia, a man-made stone used in place of diamonds. Cubic zirconia is the cubic crystalline form of zirconium dioxide. The synthesized material is hard, flawless and bears great resemblance to a perfect diamond. Due to its low cost and great durability, CZ’s are often used with rhodium-plated sterling silver to emulate diamond and platinum jewelry. This alternative gives an expensive look at a more affordable price. Show your love for the earth and your sweetheart by choosing lab created cubic zirconia CZ that reduces destructive impact caused by the mining of diamonds. The majority of our jewelry is made with cubic zirconia stones. We carry cubic zirconia CZ engagement rings, stud earrings, necklaces pendants, bracelets, brooches and pins for men, women and children
