Guide Zircon VS Cubic Zirconia




They say that diamonds are a girl’s best friend, but there comes a time when we want to try something new or we don't want to have to pull off a jewelry heist to get the pieces we are looking for.
We want something that is new but somehow similar to what we are used to. When we think of that, Cubic Zirconia comes to mind. Cubic Zirconia is one of the most popular alternative for a diamond. But even though it’s slowly gaining popularity among jewelry buyers, this affordable alternative is often confused to a natural zircon. Zircon vs Cubic Zirconia: which is which and what distinguishes it from one another? The sounding of their names often leads to confusion, but there are a lot of differences between a Zircon and Cubic Zirconia.

Zircon or Zirconium Silicate is a natural gem that has a staggering optical beauty that resembles a diamond - this is the reason why it is widely popular among jewelry and gem connoisseurs. The two qualities that make it very similar to a diamond is its fire and luster. Buster describes how a certain gem or mineral reflects to light, it is either brilliant or dull. A Zircon is known to have a brilliant luster and has a reflective quality similar to a diamond. Aside from the colorless zircon (that resembles a diamond), there are other colors of zircon such as green, golden-brown, pink, purple, white, yellow and blue which is the most popular color often seen in a jewelry. The colors of Zircon compared to Cubic Zirconia, are natural but can be heat treated to either make it colorless or to enhance the color. The only thing that distinguishes a zircon from a diamond is the fuzzy appearance or double reflection it displays.


What is a Cubic Zirconia? Zirconium Oxide

A Cubic Zirconia / Zirconium Oxide on the other hand is often used as a synthetic diamond. It is a synthetic cubic crystalline or synthetic gemstone. It’s popularity as an alternative for a diamond began way back in the 1970s. The physical properties or look of a Cubic Zirconia is so similar to a diamond making it look almost identical to the naked eye. Most Cubic Zirconia is colorless but is also available in other colors. One thing that distinguishes it from a true diamond is its thermal conductivity, as cubic zirconia tends to be a thermal insulator as opposed to diamonds which are thermal conductors.

Zircon vs Cubic Zirconia

Among the information available about a Zircon and a Cubic Zirconia, here are the most important details to help you distinguish the two. A Cubic Zirconia is synthetic compared to Zircon which is a natural gem. The CZ is used in laboratories to produce a jewelry that can be an alternative to a diamond.

A Zircon compared to a Cubic Zirconia is more expensive since it is a natural gem. It’s value depends on the gem’s saturation and tone. The blue zircon with a high saturation and tone is known to have a high value.
