          Cubic Zirconias and CZ Findings

          Shop cubic zirconia (CZ) loose stones, charms and links in a rainbow of birthstone colors! Sometimes called cubic zirconium, these sparkling semiprecious synthetic gemstones are extremely durable.
          Cubic zirconia findings from Rings & Things include a 14kt GF ear wire with clear CZ and drop-loop, and 13 colors of sterling silver charms, connector links, and ear wires. The sterling findings are available with Jet black CZs + all 12 birthstone colors. Occasionally we also have limited-stock CZ beads or other special finds.
          Available in a wide variety of beautiful colors, cubic zirconias are synthetic (manmade) gemstones. Like diamonds and natural zircons, cubic zirconias have a very high refractive index. High refractive index = high amounts of sparkle!

          CZs are extremely durable and can withstand high temperatures. Cubic zirconias have a very high melting point, so most colors can be fired in kilns with metal clay, a process that would ruin most other gemstones.

          The gemological properties of CZs vary by manufacturer due to variances in the type and amount of stablizer used to make isometric (cubic) crystals. Different oxides are added to create colored cubic zirconias. After controlled annealing to ensure the flawless crystals are stable, CZs are cut into faceted gemstones. You can safely clean your cubic zirconias with any jewelry cleaner or detergent. Be sure to rinse well to avoid leaving a residue that would dull the gem's shine.

          The greatest challenge for scientists wishing to create CZs was making a crucible that could withstand the temperatures needed to melt and hold zirconium feed powder. In the 1970s, scientists in the U.S.S.R. designed a "skull crucible" that allowed commercial production to take off.
