What is the difference between moissanite and diamond gemstones

When it comes to choosing a gemstone for an engagement ring or other piece of jewelry, diamonds are often the first choice that comes to mind. However, moissanite has become a popular alternative to diamonds in recent years. In this article, we will explore the key differences between moissanite and diamond gemstones to help you make an informed decision.


The first and most significant difference between moissanite and diamond gemstones is their composition. Diamond is a naturally occurring mineral that is formed from carbon, while moissanite is a  made from silicon carbide. While both gemstones are extremely hard, with diamond ranking a 10 on the Mohs scale and moissanite a 9.25, diamond is slightly harder than moissanite.


While both diamond and moissanite are clear, colorless gemstones, they differ in their visual appearance. Moissanite has a higher refractive index than diamond, which means it has more fire and brilliance, or the ability to reflect light in a rainbow of colors. This means that moissanite can have a more sparkly and brilliant appearance than diamond.

However, this can also make moissanite appear slightly less natural than diamond, as the high level of brilliance can make it look like it has a "disco ball" effect in certain lighting conditions. Additionally, moissanite can have a greenish or grayish tint in some lights, which can be noticeable to some viewers.


One of the most significant differences between moissanite and diamond is the cost. Moissanite is a more affordable alternative to diamond, with a similar visual appearance at a lower price point. This makes it an attractive option for those who want the look of a diamond but do not want to pay the high price tag.

However, it is important to note that while moissanite is more affordable than diamond, it is still a valuable gemstone and can be priced higher than other alternative gemstones.


Both diamond and moissanite are durable gemstones that are suitable for everyday wear. However, diamond is slightly harder and more scratch-resistant than moissanite, making it a better choice for those who are rough on their jewelry. Additionally, diamond is less likely to chip or break than moissanite.

In conclusion, while both moissanite and diamond gemstones have their own unique characteristics, the choice ultimately comes down to personal preference and budget. Diamond is a classic and timeless gemstone, while moissanite offers a similar visual appearance at a more affordable price point. Understanding the differences between the two can help you make an informed decision and choose the perfect gemstone for your jewelry needs.
