Cubic Zirconia is a durable, lab-grown synthetic stone, and is an inexpensive substitute for diamond. Cubic Zirconia is commonly abbreviated as CZ. Zirconium dioxide, the natural form of cubic zirconia, was first discovered more than a century ago. However, it was not considered to be anything of value back then.
During the 1970s, Soviet scientists were searching for a substance to use in various applications such as lasers. They unwittingly created one of the most famous gemstones in the world, and the popularity of cubic zirconia has risen ever since. Especially when the blood diamonds were common in the market and people wanted conflict-free alternatives.
CZ has a hardness rating of 8.5 on the Mohs scale which makes it a pretty durable gemstone to be used in engagement rings, necklaces, earrings, and bracelets.
Cubic Zirconia has the brilliance which resembles a diamond, it is tough and is always flawless. These three factors have contributed to the increasing popularity of Cubic Zirconia. While diamonds and cubic zirconia share some similarities regarding their appearance, their chemical structure is different. Diamond is an allotrope of carbon, Cubic Zirconia, on the other hand, is zirconium dioxide.
Cubic Zirconia producers are working to increase the brilliance of CZ to make it more similar to diamonds, and since they can easily control the final product, Zirconia comes in a wide variety of colors and shapes.
