Moissanite History & Facts
WHAT IS MOISSANITE?
Moissanite is a rare, naturally occurring mineral also known as silicon carbide, which was first discovered by the Nobel Prize-winning 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 recreate this rare mineral in his laboratory. It wasn't until the late 90's that scientists - working in a research laboratory located in Research Triangle Park, North Carolina - developed the innovative thermal growing process that creates silicon carbide crystals. These crystals are fashioned into moissanite gemstones that rival any natural gemstone for fire and brilliance. These man-made gems are more durable than diamond, sapphire, ruby or emerald.
IS MOISSANITE A BRAND OF DIAMOND OR A SIMULATED DIAMOND?
No. Moissanite is not a substitute for diamond, either scientifically, chemically or emotionally. Charles & Colvard created moissanite is a unique gem with its own set of chemical and optical properties that exhibit more fire and brilliance than any other gemstone.
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 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.
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.
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.
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.
IS MOISSANITE GRADED ON 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).
DOES MOISSANITE HAVE INCLUSIONS?
Yes. Moissanite can have needle-like inclusions that can be seen under 10x 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.
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.
Moissanite is one of the toughest known gemstones. Studies in high pressure research have shown that moissanite is highly resistant to breaking and chipping.
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, it is best to be gentle with your valuable treasures. 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.
