Unsurpassed Brilliance & Fire – All About Moissanite

Elongated Cushion Cut Moissanite Ring South Africa

What is moissanite ?Overview

Moissanite is an exceptionally beautiful and extremely rare mineral, which occurs naturally in the form of silicon carbide. Almost 2.5 times more brilliant than a diamond, this near-colorless gem has its own distinctive properties and splendor that make it truly one-of-a-kind.

Moissanite was named after French chemist Henri Moissan, who discovered it in the year 1893. During the examination of rock samples from a meteor crater located in Canyon Diablo, Arizona, he spotted this crystal and mistook it for a diamond. It was only after 11 years that he was able to identify it as silicon carbide.

The rarity of this gem also led scientists to find a way to synthetically create it using particles of naturally occurring moissanites.

Moissanite has a refractive index that is higher than that of a diamond and other popular gems such as sapphire and ruby. This particular property determines the brilliance of a gem, and with a refractive index of 2.65 to 2.69, a moissanite certainly outshines every other stone.

The same can be said about its dispersion (fire), which refers to the spectral (rainbow) colors that reflect back when light enters a non-opaque object. Moissanite has a dispersion of 0.104, which exceeds all other gemstones

Hardness & Strength

Moissanite one of the hardest substances known to mankind. It is durable and extremely resistant to breakage, chipping and scratches. With a rating of 9.5 on Mohs scale of mineral hardness, this gem’s strength is extremely commendable.

This gem has a stable color that does not usually change. It must be noted that tests have been conducted to prove that moissanites are more resistant to heat than several gemstones, including diamond. The brilliance of a moissanite remained unaffected even when subjected to heat at 2000 degrees Fahrenheit.

Quality & Grading


The majority of moissanites sold today are near-colorless. But at times, they do have undertones of yellow that are visible under certain lights. Color does play a role in determining the value of a moissanite with the colorless and near-colorless versions demanding a higher price than the tinted ones.


Typically, moissanites sold in the market are eye-clean, which means they do not have inclusions visible to the naked eye. Upon magnification, however, you may find needle-like inclusions that are inherent to the crystal’s growth process. The clarity of a moissanite is graded by examining the inclusions that can potentially affect the gem’s optical appeal.


Moissanite is a hard gem and can be cut into any desired shape, but round brilliant remains the most popular one. It is also available in other shapes, such as oval, pear, princess, cushion, heart and marquise.


Moissanites have low density and therefore weigh less. The carat weight of this gem is 10% less than that of a diamond.

Moissanite “shows” less than diamonds do. Let us explain:

If you want a 2+ carat diamond look to your ring, you will need a 3+ carat moissanite. The reason this is, is because of the difference in how the stones are measured. Diamonds are measured by carat (weight) and moissanite is measured by its size in millimeters. Especially in fancy shapes, this gets very skewed. In your head, what you envision as a 2 carat diamond, is probably a “spready” diamond, because that is most of what is sold and shown on Instagram. This means that the stone is shallower, but has more finger coverage
