Moissanite Frequently Asked Questions

What is moissanite?
Moissanite, also known by its chemical name, silicon carbide (SiC), is a naturally occurring mineral found in very limited quantities or as minute particles in the earth. The rarity of natural moissanite crystals large enough for jewellery prohibits their use.

Recently, Charles & Colvard developed a way to produce in a laboratory, large gem-quality crystals which can be faceted into near-colourless jewels with incomparable fire and brilliance. Charles & Colvard created Moissanite® is truly a unique and beautiful blend of art and science.

What shapes/ sizes does it come in?

Whatever your desire, there is a cut to accentuate the fire and beauty inside, a cut to suit you. For a full chart of available moissanite shapes and sizes please see our Stone Guide page. All stone can be set in 18ct white/ yellow gold, platinum or palladium.

How is it different to a diamond?
Moissanite is not a “simulated” diamond or a diamond substitute but a stunning jewel in its own right.

Moissanite's remarkable dispersion (fire)—its ability to break white light into the spectral (rainbow) colors make it extremely popular. In fact, fire can be measured scientifically and with a dispersion of 0.104 moissanite has nearly 2.4 times the fire of diamond

In addition to this, moissanite has superior brilliance and luster—its ability to reflect more white light back to the viewer. In fact, brilliance can be measured scientifically and is directly influenced by a jewel's refractive index. With a refractive index of 2.65-2.69 moissanite has nearly 10% more brilliance than diamond


Will it ever change its appearance?
Every moissanite jewel comes with a lifetime warranty that it will never change colour, fade or lose its beauty. Moissanite is also extraordinarily heat resistant, durable and tough. It is extremely resistant to scratching, abrasion, breaking and chipping - but like all precious stones, including diamond, it is not indestructible.


Is moissanite natural or man-made?
Moissanite does occur in nature however, the crystals are tiny and rare. In fact, they are so scarce that enough gem-quality natural moissanite doesn't exist to create a pair of solitaire earrings.

Today, beautiful lab-created moissanite jewels are available through a proprietary and patented thermal growth process exclusively through the house of Charles & Colvard. The growth process is very involved, technology intense and expensive—all factors which prevent mass production of Charles & Colvard created Moissanite®.


Who Buys Moissanite?
Moissanite jewellery is worn by both men and women all over the world. However, women especially are attracted to the big, bold look of moissanite jewellery with its unrivalled fire and brilliance.


Is moissanite a brand of diamond, synthetic or simulated diamond?
No. Moissanite is not a substitute for diamond scientifically, chemically or emotionally. Charles & Colvard created Moissanite® is a unique near-colourless jewel (chemical composition: SiC) that stands on its own and has superb fire and brilliance as compared to any other jewel and offers the value, quality and fashion that self-purchasing women demand.


How is moissanite difference from CZ?
Moissanite and cubic zirconium (or CZ) are very different from each other. While they both are near-colourless, their similarities are limited to colour. Moissanite has unique chemical, optical and physical properties which easily identifies and separates it from CZ.

Cubic zirconium is widely synthesized by a number of companies, for use as an inexpensive diamond look-alike or simulant. By comparison, moissanite is not a diamond simulant, but rather a unique jewel, unlike any other.

In contrast, naturally occurring quantities of moissanite are so minute and scarce that they are not suitable for use in jewellery. Only one company in the world, Charles & Colvard, has mastered the art of advanced technology and owns patents for creating moissanite crystals for jewellery use. These rare jewel-quality crystals are produced in limited quantities and are carefully hand-faceted into moissanite jewels once each crystal meets stringent quality controls.
