Cubic zirconia studs set in sterling silver, available with either 4mm or 6mm clear stones.
Cubic zirconia (or CZ) is the cubic crystalline form of zirconium dioxide. The synthesised material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. Because of its low cost, durability, and close visual likeness to diamond, synthetic cubic zirconia has remained the most gemologically and economically important competitor for diamonds since 1976
