Charles & Colvard FAQ

Why is Moissanite Sold By Millimeter Rather Than By Carat Weight?

The carat is the traditional unit of measurement for a diamond’s weight. Moissanite is not measured in carats because it weighs approximately 10 percent less than diamond. For example, a 6.5mm round diamond would weigh 1.0ct, while a 6.5mm round moissanite would weigh 0.88ct. The two stones would be the same size – 6.5mm in diameter. All stones for sale are listed with their size in millimeters and the diamond equivalent weight (DEW) in carats.

What is Moissanite By Charles & Colvard and How Does It Differ From Forever One™ Moissanite?

Moissanite by Charles & Colvard is a cut above other moissanite on the market, with the exception of Forever One. Created from the same patented silicon carbide material that offers unparalleled clarity, Moissanite by Charles & Colvard is truly a revolutionary value. The distinction between Forever One and Moissanite by Charles & Colvard is made through our applied expertise throughout the process, and the discerning approach we take to ensure the quality of Forever One remains far above any other offering available today. By closely evaluating clarity and cut, we’re able to determine which stones meet our exemplary standards for Forever One, and those that bear the Moissanite by Charles & Colvard name.

Is Moissanite Heat Resistant?

Yes. Moissanite exhibits more heat resistance than many other gemstones, including diamond. Tests prove that at 2000ºF—higher than the equivalent intensity of a house fire—moissanite gems remain intact and as brilliant as the day they were created. This heat tolerance makes moissanite unlikely to suffer damage during jewelry repair.

Does Moissanite Break Easily?

No. Moissanite is one of the toughest known gemstones. Charles & Colvard provides a Limited Lifetime Warranty that protects against damage to the stone.

Is Moissanite Resistant to Scratching?

Yes. Moissanite is durable, tough and extremely resistant to scratching and abrasion. With a hardness of 9.25-9.50, moissanite is harder than all other gemstones except diamond. Charles & Colvard provides a Limited Lifetime Warranty that protects against damage to the stone.

Does Moissanite Have Inclusions?

Yes. Moissanite can have needle-like inclusions that can be seen under 10x magnification. They are not visible to the naked eye and do not affect the clarity of the stone. It’s worth noting that nearly every gem has some sort of inclusion. They are unique to each gemstone and occur in the formation of the crystalline structure.

Is Moissanite Graded On the Gia Diamond Color Grading Scale?

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: colorless (D-E-F range), near-colorless (G-H-I range) and with faint hues of color (J-K range).

Will Moissanite Fade Or Change Color Over Time?

No. There are no likely situations in which the color of moissanite will be permanently changed. Moissanite does undergo a temporary color change when exposed to extreme heat from a jeweler’s torch during jewelry repair, but with proper bench techniques there will be no lasting damage and the stone will return to its normal color once it cools.

Do Other Gemstones Have More Fire Than Moissanite?

Moissanite's fire exceeds that of any popular gemstone, including diamond, ruby, sapphire and emerald. Fire can be measured scientifically; with a dispersion of 0.104, moissanite has 2.4 times the fire of diamond. No other gemstone or jewel compares to Charles and Colvard Created Moissanite® with regard to fire.

What Gives Moissanite Its Fire?

A gemstone's fire is determined by a gemological property called dispersion. Dispersion refers to the prism effect that occurs when pure white light enters a non-opaque object, breaks into spectral (rainbow) colors, and reflects back to the viewer. Moissanite’s dispersion is 0.104, which exceeds that of any gemstone including diamond, ruby, sapphire and emerald.

Will the Brilliance Of Moissanite Ever Fade?

No. Charles & Colvard provides a Limited Lifetime Warranty which guarantees that every Charles & Colvard created moissanite gemstone will maintain its brilliance and fire forever.

What Property Of Moissanite Makes It Sparkle With Such Exceptional Brilliance?

The most significant optical property affecting a gemstone’s brilliance, or sparkle, is the brilliance refractive index or BRI. The BRI of moissanite ranges from 2.65 to 2.69, meaning it displays more brilliance than diamond (with a BRI of 2.42) or any other popular gemstone.

How is Moissanite Graded for Clarity?

Charles & Colvard employs graduate gemologists certified by the Gemological Institute of America. Each Charles & Colvard gem is studied by trained grading specialists using a 10x jeweler’s loupe for any imperfections that may affect it’s optical performance.

Is Moissanite an Ideal Cut Stone?

Carefully and precisely faceted, each Charles & Colvard created moissanite gemstone is cut according to exact angles and proportions specific to moissanite. When cutting moissanite, precision is critical to maximizing its brilliance and enhancing its incredible fire.

Is Moissanite a Brand Of Diamond Or a Simulated Diamond?
