About Moissanite

What is Moissanite?

Moissanite is a rare and naturally occurring mineral. This is a form of crystalline silicon carbide created in laboratories and widely used as a diamond simulant. Moissanite was discovered by Nobel Prize-winning French chemist and pharmacist, Dr.Henri Moissan while examining rock samples from a meteor crater located in Canyon Diablo, Arizona, in 1893.

Moissanite Clarity

Clarity is a measure of the surface blemishes and internal inclusions of a gemstone. For the purpose of comparison to natural diamonds, experts agree the clarity of Moissanite is on average the equivalent to VS clarity on the GIA scale.

Moissanite Color

Moissanite grading uses a color grading scale that is based upon the GIA diamond color grading scale. There are three grades of moissanite available today.

“Classic” moissanite has a yellowish or brownish color, often compared to J through K color diamond. This range works best with yellow gold or rose gold settings and vintage styles.

Moissanite is also available in colors equivalent to “Near Colorless” (G-H-I range) and “Colorless” (D-E-F range). This gives moissanite buyers great options for mimicking their favorite diamond looks and styles.

Moissanite Brilliance and Fire

When you’re looking at a diamond, you’ll notice both brilliance (white flashes) and fire (colored flashes). Moissanite also shows both.

The most significant optical property affecting a gemstone’s brilliance, or sparkle, is the High refractive index

Moissanite is known for its high refractive index of 2.65 to 2.69, which is notably higher than diamond, sapphire and other gemstones are known to be very brilliant. Brilliance is the flashes of white light exiting the top and sides of a gemstone. The higher the refractive index of a gemstone, the more brilliance the jewel emits.

Moissanite’s fire, the flashes of colored light, is even more impressive, being more than twice that of a diamond.
