Born From the Stars

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.

Many years later at a North Carolina research campus, Charles & Colvard®, perfected and patented the innovative process that creates silicon carbide crystals with such purity that it rivals any earthly gemstone for fire and brilliance. In these gems, which are more durable than diamond, sapphire, ruby, or emerald, this fire and brilliance will last forever.

WHAT IS MOISSANITE?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. Discovered in 1893 by French Nobel Prize-winner, Dr. Henri Moissan, the jewel was later named in his honor.

HOW IS CHARLES & COLVARD CREATED MOISSANITE® MADE?

Single-crystal moissanite is manufactured through a patented thermal growing process The process is very difficult and expensive, thus preventing mass production. Today, Charles & Colvard® is the sole source and global distributor of created moissanite, with patents for the manufacturing process itself, as well as for its use as a jewel.

Will Moissanite change color or clarity?

Every Charles & Colvard Created Moissanite® gemstone is produced within exacting specifications and high quality control standards. The Charles & Colvard® Certificate of Authenticity ensures that every Charles & Colvard Created Moissanite® gemstone is an original product which has been manufactured in controlled facilities by highly skilled specialists using the latest technology. Moissanite created gemstones are released for sale only after having met stringent quality control standards.

 

What makes moissanite “sparkle”? What characteristics of moissanite give it such exceptional brilliance?

The Refractive Index (RI) of a gemstone is the most important optical property affecting its potential brilliance (sparkle). It is this refractive index that gives Moissanite it's brilliance. With an RI of 2.65 – 2.69, moissanite displays more brilliance than diamond (RI 2.42) or any other popular gemstone, such as ruby (RI 1.77) and sapphire (RI 1.77).

What inclusions does Moissanite have?

Though moissanite is not sold with eye-visible inclusions, needle-like inclusions are inherent to the crystal growth process and can be seen under magnification.

How is moissanite graded for clarity?

Using a 10x loupe, each individual jewel is examined for inclusions that may affect moissanite’s optical performance.

Color

Is moissanite available in different colors?

Most moissanite sold today is near-colorless.

Is moissanite graded on the GIA diamond color grading scale?

No. The standard GIA diamond color grading scale is not designed to rate moissanite. Unlike diamonds, which range from colorless to brownish to fancy yellow, Charles & Colvard Created Moissanite® can have slight undertones from green, yellow, gray, and teal.

Are moissanite jewels hand-cut or mass produced?

Every Charles & Colvard Created Moissanite® gemstone is precisely hand-cut by a master gem cutter to create maximum brilliance which intensifies its ultimate fire.

What shapes are available?

While round brilliant continues to be the most popular cut for moissanite, fancy cuts such as cushion, heart, marquise, octagon, oval, pear, princess, radiant, square brilliant, triangle and trillion are also available in limited quantities.
