What is Moissanite and How Does it Differ From Diamonds?

A Synthetic gemstone that has gained popularity as an alternative to diamonds in jewelry. It is composed of silicon carbide (Sic) and exhibits similar optical properties to diamonds. However, there are several key differences between Synthetic and diamonds:                                                                           

Composition and Origin

Moissanite: Moissanite is named after French scientist Henri Moissan, who discovered the mineral in a meteorite crater in Arizona in 1893. Almost all moissanite used in jewelry today is lab-created, although its natural form is exceptionally rare and found in certain types of meteorites.

Diamonds: The Diamond has the highest reflective index, which gives them their characteristics. Moreover, diamonds are founded under the Earth, typically at a depth of 100 to 200-kilometer dipper, and they are formed under high pressure and temperature.

Physical Properties

  • Brilliance and Fire: It exhibits a high level of brilliance and fire, meaning it reflects light exceptionally well and produces colorful sparkle. Some people even consider moissanite to have more sparkle than natural ones.

  • Hardness:  This is the hardest known natural substance and ranks 10 on the Mohs scale of hardness. It is also very hard and ranks at 9.25, making it a durable gemstone suitable for everyday wear.
  • Color: Moissanite color grades are colorless, near colorless, light yellow and yellow in white shade. Whereas natural diamond color grade are set by GIA which is from D to Z, where DEF refers as colorless, GHI as near colorless, JKL as faint, MNOPQRS as near yellow and TUVWXYZ as yellow.

Price and Affordability

  • Moissanite: This is generally more affordable than diamonds of similar size and quality. Its lower production cost and availability contribute to its relatively lower price point.
  • Diamonds: It can vary greatly in price depending on factors such as carat weight, cut, color, and clarity. High-quality Stones can be significantly more expensive than Synthetic.

Composition Silicon carbide Carbon
Refractive index 2.65 2.42
Hardness 9.25 10
Price More affordable More expensive
Color Available in a variety of colors Typically colorless

Environmental and Ethical Considerations

  • Moissanite: It has a smaller environmental impact compared to mined diamonds. It does not require extensive mining operations, reducing the ecological footprint associated with diamond mining. It is also considered a conflict-free alternative.
  • Diamonds: The diamond industry has made efforts to improve ethical mining practices, but concerns regarding conflict, human rights violations, and environmental impact still exist.

When it comes to Rings, are jewelry pieces featuring the center stone or accent stones. These rings are popular due to their affordability, beauty, and durability.

  • Optical Properties: It has a high refractive index, resulting in exceptional brilliance and fire, sometimes even more than Authentic stones. Both have a unique sparkle and brilliance due to their refractive properties.
  • Hardness:  This is the hardest natural substance and ranks 10 on the Mohs scale, while moissanite ranks at 9.25, making it a highly durable gemstone.

1. What is the main difference between Moissanite and Diamond?

The main difference is their composition. Diamonds are made of carbon, whereas; moissanite stones are made of silicon carbide. This leads to differences in their physical properties like hardness, brilliance, and fire (color dispersion).


2. How does the hardness of Moissanite compare to Diamond?

Diamonds rank a 10 on the Mohs scale of hardness, the highest possible rating, making them the hardest known mineral. Moissanite stones, however, rank 9.25 on the Mohs scale, making them slightly less hard, but still very durable for everyday wear.


3. Does Moissanite show more color than Diamond?

Moissanite exhibits a higher degree of fire, which is the display of colors when light is refracted. The fire in moissanite is often more colorful and rainbow-like, whereas diamonds reflect light in clear, sharp flashes.
