Cubic Zirconia Guide

Cubic Zirconia

Cubic Zirconia Information

What is Cubic Zirconia?
  • Cubic zirconia (also called CZ) is a synthetic crystalline substance used as an affordable alternative to diamonds.
  • Though much less expensive than diamonds, the brilliance and crystal clarity of cubic zirconia make it one of today's most popular stones for an attractive-yet-inexpensive, diamond-like jewelry.
  • Cubic zirconia is not a mineral; it is a man-made substance, not to be confused with the natural gemstone zircon.
Cubic Zirconia History
  • In 1937, German mineralogists discovered the natural mineral form of the gemstone in a single site. It has never been found in nature again.
  • The current synthetic version of cubic zirconia is a crystalline form of the metallic element zirconium dioxide. It was first produced in a laboratory in 1977.
  • Cubic zirconia crystals are made by melting powdered zirconium and zirconium dioxide together by heating them up to 4,982ºF.

Cubic Zirconia - Quality

  • Unlike diamonds, cubic zirconia is simulated to be flawless. CZ can be perfectly structured, free of inclusions, totally transparent and possess a brighter fire.
  • Like other gemstones, cut, size and shape influence how light is refracted and will affect the stone's brilliance.
  • Like diamonds and other gemstones, cubic zirconia has is own grading scale to measure quality.

Cubic Zirconia vs. Diamonds

  • A colorless cubic zirconia is extremely difficult to distinguish from a diamond, and appears identical to the untrained eye.
  • While a diamond is a naturally occurring gemstone, cubic zirconia is simulated.
  • Diamonds are the hardest gemstone in the world, a 10 on the Mohs scale of hardness. Cubic zirconia is softer, but still considered a hard gemstone with an 8.5 rating.
  • The denseness of cubic zirconia makes it about 75% heavier than diamonds.
  • Cubic zirconia tends to contain more flashes of color than the typical diamond.
  • CZ's very high refractive index and transparency mimic the look of the most expensive diamonds in clarity and brilliance.
  • Cubic zirconia does not have cleavages, making them less brittle and susceptible to chips and cracks than diamonds.

Cubic Zirconia Styles

  • Cubic zirconia is used in rings, pendants, bracelets, earrings, other pieces where you might find diamonds. It is often set in valuable metals like gold, sterling silver and platinum.
  • The gemstone is available in a variety of attractive colors, which are made by using different oxides. Colored cubic zirconia is extremely popular in fashion jewelry.
  • Cubic zirconia is cut in the same shapes and styles as diamonds. Learn about diamond cuts and styles in the diamond buying guide.
