Moissanite vs Diamond

 What Is Moissanite?

Moissanite is a naturally occurring silicon carbide and its various crystalline polymorphs. It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893. Silicon carbide is useful for commercial and industrial applications due to its hardness, optical properties, and thermal conductivity.“Moissanite is simply a man-made diamond Look-A-Like. Moissanite is a stone rarely found in nature which means they are artificially made to mimic diamonds. Additionally, moissanite is grown in a controlled environment where they require no mining to produce and their origins are easily traceable. Moissanite is not a type of diamond. It is not also a diamond imposter, just like CZ (cubic zirconia). Moissanite is not even a diamond substitute nor a brand name for a diamond! Moissanite itself is a unique and genuine stone on its own. Which means moissanite is in its way the ultimate gem.

1: Durability

Moissanite isn’t very far behind, at 9.25. It is the second hardest gemstone used in jewelry. 

Diamonds are easily one of the hardest natural substances on the planet. On the Mohs scale of hardness, it ranks supreme at number 10.

2: Brilliance

Moissanite disperses light very well and is more brilliant than a diamond.

Diamonds refer to the ability to reflect white light, is a good measure of how much a diamond will ‘sparkle’

3: Color

Moissanite stones are not graded on color. Classic moissanite is not colorless and many feel that its color is similar to a GIA-certified K-color diamond.

While certified diamonds are graded on color and can be compared with one another.

4: Price

Moissanite of similar appearance and size can cost up to 90% less than a diamond, with a 1-carat moissanite only setting you back about $400.

That an average 1-carat diamond costs upwards of $4000, with the average cost of a diamond engagement ring being $5000. 

5: Ideal Size

Moissanite’s exhibits a rainbow effect which can look fake and is especially noticeable in larger moissanite stones. Stick with smaller sizes.

Diamonds sparkle the same at any carat weight. Go big, go small, go whatever you like.

Why do People prefer Diamonds to Moissanite?

Moissanites are man-made, whereas an earth-mined diamond is naturally formed over millions of years, deep within the planet’s mantle. A diamond is rare. Like every couple’s love story, every diamond’s journey is unique as it forms through the Earth’s crust to ultimately become an enduring symbol of love when used in a diamond engagement ring.

Selecting a Moissanite

While diamonds are graded by cut, color, clarity, and carat, moissanite is graded by color only and is not measured by the standards of the 4Cs. For diamonds, the cut is the most important factor as it brings out the stone’s brilliance. 

Moissanites are generally flawless and while they may have different internal characteristics, these do not affect the clarity of the stone and are not visible to the naked eye. Diamonds, on the other hand, often contain some flaws. Even the best diamonds may have tiny flaws within them. This is one indication of a diamond’s authenticity.

In terms of carat, most retailers tend to measure moissanite in millimeters, unlike diamonds which are measured in carats. Due to their lower density, moissanite weighs about 10% less than a diamond. This means that while a 1-carat diamond and a 6.5mm moissanite would be equal in size (in mm of the diameter), the moissanite would weigh about .88 carats.
