The perfect combination of art & science

Moissanite is a created jewel that was born from a rare geological find made more than 110 years ago. Discovered in 1893 by French scientist, Dr. Henri Moissan (who later became a Nobel Prize winner), moissanite can trace its origins to particles found in a meteor crater located in Arizona. These natural moissanite crystals were too scarce and tiny to set into jewelry. Now, through the power of advanced technology, Charles & Colvard created Moissanite is available to you.

Stands the test of time

Second in hardness only to diamond, moissanite is durable and tough. It is extremely resistant to scratching, abrasion, breaking and chipping. Charles & Colvard created Moissanite comes with a Limited Warranty that ensures it will never change color, fade or lose its brilliance or fire. Plus every gorgeous jewel comes with a Charles & Colvard Certificate of Authenticity.

How is moissanite created?

Single-crystal moissanite is manufactured through a patented thermal growing process. The proprietary process is complex, time consuming, and expensive, thus preventing mass production. Today, Charles & Colvard, Ltd., is the sole source and global distributor of created moissanite and holds patents for its use as a jewel. Every Charles & Colvard created Moissanite jewel is produced within exact specifications and high quality control standards. Each jewel is hand-faceted by a skilled gemstone cutter to create its maximum brilliance and enhance moissanite’s exceptional fire. The favorite shape for moissanite is round, however, moissanite is also available in limited quantities in most of the fancy shaped cuts including: castle (round shape), cushion, heart, marquise, oval, pear, radiant, square brilliant (princess shape), triangle and trillion.

Features and benefits


With a refractive Index (brilliance) of 2.65-2.69. moissanite has a big, bold look with more brilliance and sparkle than other popular jewels. Refractive index (brilliance) is a gemstone’s optical property that directly relates to a jewel’s brilliance (the higher the refractive index, the higher the potential brilliance). Brilliance equals the flashes of white light a jewel or gemstone returns to the eye. Brilliance is a valued attribute in gemstones.)


Moissanite's dispersion is (fire) 0.104, giving it more fire than other popular gemstones, and 2.4 times the fire of diamond. Dispersion (fire) is a gemstone’s optical property; the breaking up of white light into spectral (rainbow) colors as light passes through a jewel or gemstone. Dispersion is a prized attribute in gemstones.)


A 9 1/4 hardness on the Mohs scale, moissanite is harder than ruby or sapphire (9) and second only in hardness to diamond (10). Exceptionally resistant to scratches and abrasion.

DEW (Diamond Equivalent Weight)

Because Moissanite’s specific gravity is 10% lighter than diamond, Moissanite jewels are specified with their diamond equivalent weight (DEW). For example, a 6.5mm Moissanite will exactly fit a setting that takes a one-carat diamond, but will actually weigh 0.88 carats. Moissanite is typically sold by diamond equivalent weight so that it matches up with diamond sizes and your expectations.


Each moissanite jewel is produced within exact specifications and carefully hand-faceted by a skilled gemstone cutter. Cut to high quality standards, moissanite’s unique cut proportions maximize the jewel’s brilliance and enhance its exceptional fire.

Certificate of Authenticity & Limited Warranty
Each moissanite jewel is guaranteed to retain its fire and brilliance.

Jewelry care & cleaning

While moissanite is extremely hard, durable and resistant to abrasion and chipping, it like all other gemstones, is not indestructible. Care for your moissanite jewelry just as you would other fine jewelry, taking precautions not to wear rings and bracelets when doing rough work with your hands to avoid sharp blows. Moissanite jewelry can be cleaned the same way you would other fine jewelry. Moissanite jewelry can be safely cleaned in a jewelry ultrasonic cleaner or by using a commercial (non-acid based) jewelry cleaner.

Moissanite vs. CZ:
Moissanite is harder (does not scratch easily), has more fire and sparkle, is found in nature but in such limited quantities that it must be created, will not turn cloudy or fade with time. Cubic zirconium, or cz, is softer than moissanite, will scratch easier which inherently turns it cloudy over time, looks more like glass. Both moissanite & cz can be diamond alternatives. Moissanite created gemstones give you the true look of a diamond at a fraction of the cost.

Is moissanite a new created diamond or cubic zirconium (cz)?
Moissanite is not a created diamond. Moissanite is also not another name for cubic zirconium (cz) such as Diamond Nexus, Diamonique, Russian Brilliant and Asha.
