Moissanite Vs. Cubic Zirconia—Basics You Need to Know

So, what is Moissanite? 

Moissanite: One of the most beautiful gems in the world

Moissanite is an exquisitely beautiful gemstone, and can be a good choice for an affordable engagement ring. Moissanite, a synthesized form of silicon carbide, which means that, like diamonds, it contains carbon, is a very rare mineral that is great at conducting heat and that has an incredible brightness. It is nearly as hard as diamond and will last a lifetime. Moissanite was discovered by Dr. Henri Moissan in the 1890s. And Moissanite was named in honor of Moissan later on in his life.

Moissanite has much more fire and brilliance than a diamond, which makes it an eye-catching center stone that will light up a room. If you are considering a Moissanite as an engagement ring option, you will be able to choose a large carat Moissanite engagement ring for about $300. A Moissanite ring will save you thousands from an earth-mined diamond. 

Cubic Zirconia

Cubic Zirconia has been on the market much longer than Moissanite. Cubic Zirconia comes from Zirconium Oxide, a crystalline, white powder. When it is melted under extremely high heat, it forms crystals, known as Cubic Zirconia or CZ.

Cubic Zirconia is generally viewed as cheap and of little value, making Moissanite the best diamond substitute. From a price standpoint, Cubic Zirconia is almost worthless. It does make it a nice budget option for a cheap engagement ring or a wedding ring.

Moissanite Vs. Cubic Zirconia: Color

As we know, diamonds are colorless. And how are Moissanite vs. zirconium in this way?

Moissanite vs. Cubic Zirconia: Brilliance and Fire

The quality that most greatly affects a diamond’s beauty is its Cut—which impacts how much light reflects through the diamond’s table to your eyes. White light reflection is referred to as brilliance and colored light reflection is called fire.

In general, Moissanite has more brilliance than a diamond. It has more fire and brilliance than any other gemstone, because Moissanite is double refractive, it is cut differently than diamonds to enhance the sparkle.

Cubic Zirconia contains no true brilliance or fire. It has a much lower refractive index—between 2.15 – 2.18, compared with 2.65 for Moissanite and 2.42 for diamonds. Light passes through Cubic Zirconia much differently—offering significantly less reflection back to the eye.

Moissanite Vs. Cubic Zirconia: Durability

If you have a frugal approach to buying your jewelry, you’re not going to want something that is easily scratched or damaged.

As the hardest naturally-occurring mineral in the world, diamonds rate a perfect 10 on the Mohs scale of hardness. Moissanite is the second hardest to diamonds on the Mohs hardness scale. On the Mohs scale of hardness, a Moissanite measures in at 9.25-9.5, so they are suitable for daily wear.

Cubic Zirconia ranks an 8 on the Mohs scale of hardness. Because it’s a synthetic material, it offers some durability. Cubic Zirconia can be worn in jewelry, but will certainly not have the longevity of a diamond. Cubic Zirconia becomes scratched and cloudy over time.

Moissanite Vs. Cubic Zirconia: Price and Value

Althoug Moissanite and Cubic Zirconia are similar in quite a few areas, but Moissanite or any kind of precious metal will usually more than the CZ stone.
