Moissanite FAQ

Moissanite Knowledge & History

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.

WHERE DID THE NAME MOISSANITE COME FROM?

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 specifics of which are proprietary. 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 proprietary patents for the manufacturing process itself, as well as for its use as a jewel.

HOW DO YOU ENSURE THE PRODUCT AND QUALITY IN THE PRODUCTION OF CREATED MOISSANITE?

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). 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). (See Chart below):

Will moissanite’s brilliance 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 for its lifetime.

Clarity

Does moissanite have any identifying characteristics such as inclusions?

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 to yellow to gray to teal.

Can the color of moissanite change?

No. There are no likely situations in which the color of moissanite will be permanently changed. A temporary color change will occur when moissanite is exposed to heat (torch) during jewelry repair techniques. However, with proper bench techniques, there is no resulting damage and moissanite returns to its normal color after the jewel cools to room temperature.

Cut

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 castle, cushion, heart, marquise, octagon, oval, pear, princess, radiant, square brilliant, triangle and trillion are also available in limited quantities.
