A Unique Gemstone.
Creating an entirely new and unique category of gem stone and jewellery, moissanite-chemically known as silicon carbide-is both exceptionally brilliant and amazingly unique.
Believed to have been carried to the Earth in a meteorite 50,000 years ago in trace amounts, silicon carbide now has been created in a painstaking laboratory process and then hand faceted by master gem cutters to bring out an exceptional natural brilliance.
Set into a fine piece of jewellery, moissanite produces the most fire you’ve ever seen it’s unlike anything found naturally on Earth.
Brilliance and Fire.
Moissanites characteristic sparkle is more than just a show of beauty it’s also a testament to the superior science behind the gem stone.
Moissanite is known for its high refractive index of 2.65, greater even than the refractive index of diamond at 2.42.
There is a correlation between a stones refractive index and its brilliance, simplified the higher the refractive index, the more brilliance the gem stone emits. In other words, moissanites brilliance outrivals that of diamond.
What’s more, moissanites fire of 0.104 is more than twice that of diamond (0.044). This means that moissanite emits more fire, or flashes of rainbow colored light than diamond.
With more brilliance and fire than that of diamond or any popular gem stone, moissanite is truly impressive.
Durability & Hardness.
Moissanites brilliance outshines every gem stone, yet its exceptional durability should not be overlooked.
Durability is commonly described to consist of both hardness and toughness; however, a third component of durability is stability.
Hardness refers to the gem stones resistance to being scratched or abraded and is commonly expressed as a number ranking (1 being the softest and 10 being the hardest) on Mohs relative hardness scale.
Therefore, if you were to compare hardness between gemstones, a stone can only be scratched or abraded by a material that has the same hardness or a higher Mohs hardness.
Although diamond is the hardest substance known to mankind, ranked as 10 on Mohs, moissanite is the second hardest gem stone known to man, at 9.25. Moissanites ability to resist abrasion out ranks many popular colored gemstones and is second only to diamond.
The ability of a gem stone to remain intact, withstand force (pressure) and resist breaking or chipping is known as toughness.
Determined by a substance’s atomic and chemical structure, toughness can vary directionally within a gemstone. While both moissanite and diamond are rated excellent in toughness, moissanite has a different atomic and chemical structure than diamond.
Moissanites atomic structure does not have a direction of cleavage (which sometimes is considered as a direction of structural weakness) like diamond does. Simply said, moissanite outranks diamond in overall toughness.
Stability is a material’s ability to remain intact or withstand exposure to temperature and chemicals.
Moissanite can easily withstand temperature variations during the jewellery manufacturing process or repairs at the jeweller’s bench.
In fact, moissanite has a higher vaporization temperature than diamond and can withstand temperatures reaching 2,000 degrees Fahrenheit. Moissanite is also very stable when exposed to various chemicals typically used during both manufacturing and jewellery repair.
Moissanite remains impervious to solutions and acids typically used with jewellery manufacturing liquids that commonly damage other less stable gem stones such as tanzanite or emerald.
With excellent hardness and superior toughness, moissanite is more durable than diamond and an optimal choice for a jewel that will truly endure.
Moissanite vs. CZ
At first glance moissanite resembles diamond and might be mistaken for diamond, a synthetic diamond or diamond substitute, but in fact, moissanite isn’t a diamond look-alike or a ‘me-too’ stimulant like cubic zirconium.
Moissanite is an entirely unique gem stone with highly desirable qualities and when compared with cubic zirconium or CZ (perhaps the world’s most popular diamond stimulant), the differences are obvious as moissanites uniqueness becomes even more desirable.
CZ is an inexpensive simulated diamond look-alike and is inferior in almost every gemological property to moissanite. CZ is mass produced under a myriad of trade names and promoted with various brand names.
Compared to moissanite, CZ has a lower Mohs hardness. It scratches and abrades easily which causes many consumers to say that CZ loses its surface luster after just a few years.
Although CZ claims to scratch glass, many gemstones are ranked above glass in hardness and can easily scratch glass.
Truly, there’s no comparison between moissanite and CZ. Moissanite continually stands out as superior.
Moissanite vs. Synthetics.
The difference between synthetics and simulants might seem to be confusing as some synthetics could be marketed as simulants.
Simply defined, a synthetic gemstone is basically the same as its natural counterpart and has essentially the same chemical, physical and optical properties; however, it is created by man using laboratory processes.
For example, a synthetic ruby is essentially the same mineral as a ruby grown by mother nature; however, the synthetic variety is grown by man in a lab.
On the other hand, stimulants are created to resemble other substances or gemstones.
Stimulants do not necessarily share similar properties. For example, a rhinestone might resemble a diamond or moissanite; however, a rhinestone is made of glass and doesn’t share similar properties with either diamond or moissanite.
One of the most popular diamond stimulants or look-alikes is cubic zirconium. CZ is also a synthetic as it is manmade.
Lab-created moissanite; however, is best known to be in a category of its own and is marketed and sold as a unique gem stone.
Moissanite vs. Diamonds.
Brilliant, durable and near-colorless diamond and moissanite are often compared. However, under closer examination, you can see that these two unique stones have several key differences.
The most obvious difference is that moissanite and diamond are two entirely different gem stones with distinctly different chemical compositions, physical characteristics and optical properties.
Moissanites chemical composition is silicon carbide and diamond is composed of carbon. While both sparkle, moissanite actually has a higher brilliance than diamond when you compare refractive indices.
Moissanites measurement of brilliance or refractive index (RI) of 2.65-2.69 is about 10% higher than diamonds RI of 2.42. Not only does moissanite have a higher refractive index than diamond, but its dispersion (fire) measured at 0.104 is nearly two and a half times more than diamond’s (0.044).
Interestingly diamond has a natural affinity to grease and therefore it easily attracts grease which builds up on a diamond’s surface and can reduce its luster appearance. Moissanite is less likely to attract grease, sparkling brightly even when it hasn’t been cleaned in a long time.
Moissanite is also more durable than diamond and less likely to cleave into two pieces when force is applied. What’s more, today’s commonly promoted engagement ring diamond is lower in quality, and moissanites exceptional cutting is evident by the way moissanite out shines many diamonds.
In every way, moissanite is a superior choice for beautiful, unique jewelry.
Discovered more than 100 years ago in particles taken from an Arizona meteor crater, silicon carbide begins its journeys through a transformational process to become moissanite, a spectacular gem stone of the 21st century.
Now, through the combination of advanced technology and proprietary processes, moissanite is carefully created by Charles & Colvard.
Cherished worldwide, the gem stone is acclaimed for its exceptional brilliance and dispersion (fire) – properties that in moissanite exceed most popular gemstones and are greater than a diamond.
Moissanite is also harder than ruby, sapphire and other popular gemstones and second in hardness only to diamond.
Moissanites history truly showcases the feats of modern science and artisan skill in creating a gem stone so universally appealing.
