Charles & Colvard Created Moissanite® is a unique near-colorless jewel made from silicon carbide (SiC) that outshines all others with its unsurpassed fire and brilliance. Moissanite, also known as silicon carbide (SiC), is a naturally occurring mineral found in limited quantities or as small particles in the earth. Moissanite is not a diamond simulant or diamond substitute; it is its own jewel. The rarity of large natural moissanite crystals prohibits their use in jewelry making.
For years, scientists tried to re-create this extraordinarily brilliant material. Only recently through the power of advanced technology has Charles & Colvard® developed a way to duplicate this unique and near-colorless jewel by producing large, gem-quality crystals. Moissanite is truly a unique and beautiful blend of art and science.
Natural silicon carbide is impossibly rare on Earth; in fact, it first gained fame when tiny particles were discovered by the Nobel Prize-winning French chemist Dr. Henri Moissan at the site of a massive meteorite strike in Arizona. This intriguing new stone was named Moissanite in his honor, and Moissan spent the rest of his life attempting to re-create this rare mineral, which is among the hardest materials on Earth.
A patented thermal growing process is used to create single-crystal raw moissanite gems. The process is lengthy, complicated, and expensive, which limits the output (it takes 2-3 months for the creation of a single gem). Charles & Colvard’s proprietary manufacturing process and moissanite’s use as a gem currently make Charles & Colvard® the leading source and global distributor of created moissanite.
Years of development have led to a rigorous process for the production of created moissanite, which follows exacting specifications and very high standards of quality control. The Charles & Colvard® Certificate of Authenticity certifies that every gem is an original product manufactured in meticulously controlled facilities by highly skilled specialists. Post production, all created moissanite undergoes stringent testing for quality and purity, along with four rounds of grading, before being released for sale.
The most significant optical property affecting a gemstone’s brilliance, or sparkle, is the Refractive Index, or RI. The RI of moissanite ranges from 2.65 to 2.69, meaning it displays more brilliance than diamond (with an RI of 2.42) or any other popular gemstone.
Yes. Moissanite has needle-like inclusions that can be seen under magnification; however, 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 characteristics which occur in the formation of the crystalline structure.
The Charles & Colvard® manufacturing facility is managed by a Graduate Gemologist certified by the Gemological Institute of America. Each gem is studied by a trained gem examiner using a 10x jeweler’s loupe for any inclusions that may affect moissanite’s optical performance.
Yes. In addition to Forever Classic™, Forever Brilliant®, and Forever One™ we offer treated (coated) moissanite in a number of colors, and occasionally, a very limited quantity of natural green, blue, gray, and/or yellow. However, the majority of moissanite sold is near-colorless.
There are three grades of moissanite available today. Forever One™, Forever Brilliant®, and Forever Classic™. Charles & Colvard Forever Classic™ occupies the J–K range. Charles & Colvard Forever Brilliant® spans the versatile, near-colorless G–H–I range. And the lauded D–E–F range is graced by the purest of the pure – Charles & Colvard Forever One™, a colorless gem so white and blazingly brilliant that it takes the breath away.
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 (for example, from a jeweler’s torch during jewelry repair), but with proper bench techniques there will be no lasting damage, and the gem will return to its normal color once it cools.
Because hand-cutting is the only way to release the brilliance that intensifies a gem’s fire, each and every Charles & Colvard Created Moissanite® gemstone is hand-cut by master gem cutters.
Yes. Moissanite is available in twelve shapes and dozens of sizes. The most popular cut continues to be the round brilliant cut, but fancy cuts such as cushion, emerald, pear, heart, marquise, baguette, oval, radiant, triangle, and square brilliant are available as well.
A gemstone’s fire is determined by a quality 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 and has 2.4 times the fire of diamond (0.044), and much more dispersion than ruby (0.018), sapphire (0.018), and emerald (0.014).
The chart below compares moissanite with other popular gemstones, including diamond, ruby, emerald, and sapphire, on key characteristics such as hardness, fire, and brilliance.
|Hardness mohs Scale||Toughness|
|EMERALD||1.58||0.014||7.50||GOOD TO POOR|
In cleavage direction, toughness is 'good'

No. Charles & Colvard® provides a Limited Lifetime Warranty which guarantees that every Charles & Colvard Created Moissanite® gemstone will maintain its brilliance and fire for its lifetime.
Yes. Moissanite is durable, tough, and extremely resistant to scratching and abrasion. With a hardness of 9.25, moissanite is harder than all other gemstones except diamond.
No. Moissanite is one of the toughest known gemstones. Studies in high pressure research have shown that moissanite is highly resistant to breaking and chipping.
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.
There are five (5) methods:
1. Use a tester specifically designed to distinguish moissanite from diamond.
2. Determine if doubling of facet junctions is visible through magnification.
3. Use a jeweler’s loupe to examine the girdle of the stone. Forever One™ and Forever Brilliant® moissanite stones are engraved on the girdle for easy identification.
4. Examine for needle-like inclusions, typically perpendicular to the table facet, which are visible in moissanite under 10x loupe magnification.
5. Examine for specific refractive and gravity indices.
Yes. The physical properties of created moissanite are very similar to those of diamond, and moissanite will test positive as diamond using a thermal diamond tester.
The carat is the traditional unit of measurement for a diamond’s weight. Moissanite is not measured in carats because it weighs approximately ten percent less than diamond. For example, a 6.5mm round diamond would weigh 1.0 ct, while a 6.5mm round moissanite would weigh only 0.88 ct. The two stones would be the same size – 6.5mm in diameter. All stones for sale are listed with their size in mm and/or the diamond equivalent weight (DEW) in carats.
Due to its rarity and unrivaled beauty, Charles & Colvard Created Moissanite® is expected to retain or increase its value over time.
You may clean moissanite the same way you would diamond or any other fine gemstone. As with any fine jewelry item, an ultrasonic cleaner can be used; however, be gentle with your valuable treasures – do not simply toss all your jewelry in at once, as this could lead to chipping. You can also clean your moissanite jewelry using a commercial (non-acid based) jewelry cleaner, or with mild soap and water using a soft toothbrush.
Yes. Moissanite is an extremely stable material. It is durable, tough, and highly resistant to scratching, abrasion, breaking, and chipping. Its high heat tolerance makes moissanite very unlikely to experience damage during jewelry repair.
