Is it a synthetic diamond?

No. The composition of a Diamond is Carbon - C, with Moissanite having a composition of Silicon Carbide - SiC 

How can it be a Diamond alternative?

Because of of the unique properties of Moissanite, it has 10% more Brilliance and 200% more Fire than a Diamond. Very few Diamonds has VVS1 clarity, which means that it can easily break because of the flaws in the stone. Moissanite is also the second hardest material know to mankind, it is harder than Tungsten Carbide and Titanium. Science has enabled us to manufacture VVS1 clarity (near flawless) gemstones, we can with confidence tell our clients, your stone will not break, something no Diamond dealer will tell his client. Apart from the above, we trust our product, and therefore provide a lifetime replacement warranty on all Moissanite we sell. 

Is Moissanite graded on the GIA diamond color grading scale?

No, but at Namaqua Moissanite we do certify and grade our Moissanite according to the GIA color grading scale at European Gemological Laboratories, a trusted local gemstone grading lab in Johannesburg. We provide a certificate that supplies the Color, Clarity, Finish and Dimensions, just like you would get with a Diamond. 

Is all Moissanite graded equally?

No. Many Moissanite suppliers do not take extra measures to ensure the certificates they receive is accurate. We have seen various Moissanite certificates sold to unaware customers that had incorrect information on it like incorrect color, grading, clarity, carat weight, dimensions, size etc. So be sure to know where you buy your Moissanite, and if you do not have a locally graded gemstone, demand your Moissanite supplier provide you with a locally verifiable certificate, or take your stone to a gemologist te verify the information on your certificate is accurate. 

How hard is moissanite?

Moissanite is the second hardest material known to mankind. Because of technological advances, we have managed to get the hardness of Moissanite up to 9.5 on the Mohs scale of hardness. Moissanite is harder than Tungsten Carbide and Titanium.

"Both titanium and tungsten carbide are considerably harder than precious metals like gold and platinum. However, tungsten carbide is one of the hardest materials in existence and substantially harder than titanium, registering a 9 on the Mohs scale of mineral hardness" - Source (Wikipedia)

Moissanite is hard enough to put in precious metals and totally suitable for everyday wear.

Cheap Chines Moissanite

Although you might be able to find cheap Moissanite gems available on the internet, you should keep in mind that there are various factors that determine the quality of a finished Moissanite Gemstone. Firstly, there is such a thing as a poor quality Moissanite stone. Some manufacturers make the stone as cheap as possible and they do not make sure the cuts are perfect. The grading on the certificates will almost always be incorrect as well, so if you bought a cheap import, be sure to verify your Moissanite is what it is supposed to be at a Gemologist before setting it in Gold or Platinum.

Is Moissanite a Cubic Zirconia?

No. Moissanite is high quality product that cannot be compared with CZ in terms of price or quality. 

CZ is not an eternal gem. 

Moissanite has extremely high scratch resistance and will never lose its brilliance or fire. 

Only Diamonds can be compared with Moissanite, and even the clearest, most expensive Diamond can't ever produce the Brilliance or Fire of Moissanite. 

What is Brilliance, Fire and Scintillation?

Diamond & Moissanite fire is simply the colored sparkle that you can see when the stone is exposed to light. 


In contrast to fire, brilliance is the colorless light that is emitted from the stone.

Scintillation is a term that refers to the flashes of light you can see when you hold a diamond in your hand and move it.
