Moissanite vs Diamond: A Comprehensive Comparison

When it comes to choosing a precious gemstone for an engagement ring, diamond has been the traditional choice for many years. However, with the advent of technology, a new option has emerged in the form of Moissanite. This article will delve into the differences between Moissanite and Diamond, and why Moissanite may be a better option for those looking for a sparkling, durable, and ethical alternative to Diamond.

What is Moissanite?

Moissanite is a naturally occurring mineral known as silicon carbide. It was first discovered in a meteorite in 1893 by a French scientist named Henri Moissan. Although Moissanite is a rare mineral, it can now be created in a laboratory using cutting-edge technology. The result is a gemstone with similar visual characteristics to diamond, but with some key differences.

What is Diamond?

Diamond, on the other hand, is a naturally occurring mineral made up of carbon atoms arranged in a crystal structure. Diamonds are formed deep within the Earth’s mantle over millions of years, and are then brought to the surface through volcanic eruptions. They are the hardest mineral known to man, making them ideal for use in jewelry and other applications where durability is a key factor.


Moissanite and Diamonds have a similar appearance, with both gems appearing as clear, colorless stones that are renowned for their fire and brilliance. However, there are some key differences in the way the two gems reflect light that can be used to tell them apart. Moissanite has a higher refractive index than diamond, which gives it a more radiant, sparkling appearance. This is because it has a greater ability to bend and split light into its component colors. On the other hand, Diamond has a lower refractive index, which gives it a more classic, elegant look. Diamonds are also typically more transparent than Moissanite, which can make it appear more “cold” or “icy.”


In terms of durability, Diamond is the clear winner. Diamonds are the hardest mineral known to man, making them ideal for use in jewelry and other applications where durability is a key factor. Diamonds are also extremely resistant to heat, chemical damage, and other forms of wear and tear. In contrast, Moissanite is a relatively soft mineral, and is not as durable as Diamond. It is more resistant to heat than other gemstones, but is still more prone to scratches and other forms of wear and tear.


One of the key advantages of Moissanite over Diamond is price. Moissanite is significantly less expensive than Diamond, with a 1-carat Moissanite costing around 1/10th the price of a 1-carat Diamond. This makes Moissanite an appealing choice for those looking for a beautiful and affordable alternative to Diamond. Additionally, because Moissanite is a man-made mineral, there is no need to worry about the environmental and ethical issues associated with diamond mining.

Environmental and Ethical Considerations

Diamond mining has long been associated with environmental degradation, human rights abuses, and other unethical practices. Many diamond mines are located in remote areas, and the mining process can result in damage to the surrounding environment, including deforestation, soil erosion, and water pollution. In addition, the diamond trade has been linked to the financing of civil wars and human rights abuses in countries such as Sierra Leone, Angola, and the Democratic Republic of Congo.

In contrast, Moissanite is a man-made mineral that is created in a laboratory. This eliminates the need for diamond mining, and the associated environmental and ethical issues. By choosing moissanite, you can feel good about your purchase knowing that it was created in an ethical and sustainable way.

Optical Characteristics

Moissanite is known for its exceptional brilliance, fire, and scintillation. These optical characteristics are what make moissanite a popular alternative to diamonds. It has a high refractive index, which means it has a higher level of brilliance than a diamond. In addition, moissanite has a unique sparkle that is different from a diamond, making it a unique and beautiful option.


Moissanite is a versatile gemstone that can be used in a variety of jewelry styles, from classic and traditional to modern and contemporary. It is also available in a range of colors, including colorless, yellow, and even pink, so you can find the perfect moissanite to match your personal style.

Warranty and Guarantee

Finally, many moissanite manufacturers offer a warranty and guarantee with their products. This means that if your moissanite ever chips, cracks, or becomes damaged, you can have it repaired or replaced. This is not always the case with diamonds, which can be expensive to repair or replace if they are damaged.
