Diamond VS Moissanite – 5 Differences You Should Know

Diamonds and moissanite are both used by jewelers to craft jewelry and other elegant precious objects.

Diamonds are highly valued gemstones made of pure carbon, while moissanite is rare shiny stones made from silicon carbide.

They both appear sparkly and are pretty durable due to their undisputable hardness on Mohr’s scale.

About Moissanite

The first moissanite was found in rock samples from a crater by a meteor in Arizona. The mineral acquires its name moissanite from french chemist Henry Moissan.

He discovered it and thought it was a diamond but later realized it was a silicon carbide compound two years after Edward Acheson had synthesized it in the lab.

The mineral occurs typically with diamonds from upper mantles in the crust and other samples collected in meteor craters and meteorites.

The love for diamonds

Diamonds occur in ultrabasic rocks such as kimberlite, which also originate from the upper mantle. The world’s love for diamonds is shown in records as early as the fourth century BC when Indians found them on river banks. They become popular as highly precious stones associated with wealth and class throughout the East and parts of Europe. Mining was ongoing in different nations, but the biggest reserve discovered in 1800 was Africa in South Africa and DRC, then Zaire. The affluent European countries started their exploitation, and the market and value have grown since.

1.Diamond is harder than moissanite

Diamonds are the hardest minerals to be recorded with a scale of 10 on Mohr’s scale, whereas moissanite ranges at 9.25 on the scale. Therefore, natural moissanite is likely to chip more than diamond, yet they both register top-notch quality over many years of use.

2.Reflective index

Moissanites have a high reflective index of 2.6, which attributes to the beautiful brilliance it emits when exposed to sunlight. However, diamond is much less reflective in sunlight and shines differently in daylight compared to moissanite.

Moissanites have different crystal alignment that contributes to a fiery rainbow reflection of white light, that gives the shinier effect compared to diamond. This unique brilliance captures most people, yet some may be put off by the rainbow flashes and opt for traditional diamonds.

On the other hand, diamonds emit reflections on three levels, which contribute to the famous sparkle. Diamonds give off brilliance, which is a reflection of white light. They also give off a rainbow shine which is the dispersion of white light, and finally, the third type of diamond light is scintillation.

Scintillation is the surface shine that combines both dispersed rainbow light and white light dispersed by diamonds in motion. Diamonds are famous for this unique sparkle, hence their preference.

3.Moissanites are more colorful than diamonds.

Moissanites appear grayish in some lights, and the bigger the jewel, the more noticeable it seems. Most gemstone enthusiasts prefer the colorless models which mirror diamonds because colored sparkles are deemed cheap. On the other hand, Diamonds maintain their naturally colorless bright whiteness, which holds however large the cut and stone are.


Due to how rare the moissanite naturally occurs, they are primarily manufactured in the laboratory, becoming readily available in the gemstone market. Most middle-income people opt for moissanite because of their considerably reduced price of engagement rings and other jewels. They appeal more to eco-conscious buyers as no mining was involved hence the essentially fair price tag.

Diamonds are both lab-created and mined, and both processes have a significant impact on humans and environmental conservation. Many types of diamonds in the market raise conflict due to how they are acquired, but all are highly-priced and fetch handsome amounts to whichever level of dealership any dealer is involved.


Diamonds are costly and are worthy investments to owners since they never go out of style and give recognition and status everywhere.

The price of moissanite varies depending on the size of the stone, which is dramatically lower than diamond’s prices.

Either super-premium or premium, moissanite exclusiveness goes in this range which may alter the value. Diamonds are created in labs much economical than naturally occurring diamonds, but their exact prices depend on clarity, the cut, carats, and even color.

Final Tought

Moissanites and diamonds both trend well in the gemstone industry, especially as jewelry and engagement rings. They both signify beauty, but diamonds show class and elegance the most. Some diamonds may be associated with conflict due to illegal exploitation, but several dealership standards ensure compensation.
