What is Moissanite?

Many have questions about diamond and moissanite. You may be surprised to learn that they are different types of gemstones. Let us walk you through the similarities and differences!

What is Moissanite?

Moissanite is called to be born from stars because it was discovered onA lady wearing a 14K Rose Gold round moissanite engagement ring the meteor that fell from the stars on the Earth over 100 years ago. 100 years later, moissanite is lab made because of rarity of natural moissanite. As you may know, it is also the most sparkling gemstone in the world! 

Moissanite vs Diamond: Side by Side! 


Natural and lab-made diamonds are significantly more expensive than moissanite. It is true that lab-made diamond is more affordable than natural diamond. However, you may be surprised to learn that moissanite is even more affordable and is often only 10% of natural diamond’s price!


It is widely said that moissanite delivers more fire and brilliance than any other gemstones on Earth!  

Brilliance in gemstones is referred to the light that is reflected from the interior of the gemstone when the light is passed through it. 

Due to the different faceting patterns in moissanite, it reflects lights differently compared to diamonds and exhibits different brilliance. It has rainbow, fiery-like flashes. Some opine that it gives an effect of “disco-ball” in sunlight due to its heightened brilliance!

It has a refractive index higher than a diamond as diamonds have a refractive index of 2.417-2.419 and moissanite with 2.65-2.69. The bigger the moissanite is, the higher chances of noticeable differences it has.  


Diamonds can range from flawless (no visible imperfections) to flawed (visible imperfections). Finding a flawless natural diamond can be as daunting as finding a flawless natural moissanite!

Moissanite is lab-made and is flawless to visible eyes.


Lab-made diamond and moissanite are colourless, displaying the shining and bright appearance. 

Natural diamond, depending on its grading, can range from colourless to mildly yellow.


Many know that diamond is very durable and are unsure whether moissanite is the same as well.

The hardness is to check the gemstone’s ability to withstand surface scratching. A common scale is called the Mohs Scale of hardness.  

You may be surprised to learn that moissanite is on a 9.25/10 on the Mohs Scale of Hardness, therefore it is suitable for everyday wear! The hardest gemstone is diamond with a score of 10/10.

Because of their durability, both diamond and moissanite are often placed as the centre stone of an engagement ring to symbolize the unbreakable bond between the couple.

Moissanite draws attention from ethical customers because it is lab-created and environmentally friendly! Lab-made diamonds are eco-friendly, too.
