Is Moissanite Harder than a Diamond?

When you invest in a piece of fine jewelry, you expect it will be durable enough to stand up to everyday wear and tear. Though lab-created moissanite is not as hard as a diamond, it does have a hardness of 9.25 on the MOHs scale, meaning it will withstand the daily rigors your jewelry will endure. This makes it harder than any other white gemstone used in jewelry making. For more information about the durability of Forever One moissanite, keep reading below.

Is moissanite resistant to scratching?

When you’re rocking a new piece of jewelry, you want to be it will last a lifetime. Unfortunately, gemstones you want to wear every day demand a certain level of hardness and resistance to scratching. Whether it’s a new pair of studs or a unique engagement ring, your jewelry always carries the risk of encountering an abrasive surface.

The MOHs scale of mineral hardness is what is used to identify the hardness of a gemstone. This scale is a quantitative and comparative measurement tool that characterizes the scratch resistance of various minerals. The MOHs scale ranges from a 0 to a 10, with a 10 being the hardest mineral. When put through scratch tests, moissanite measured at a 9.25 (in comparison, diamonds have a hardness of 10). This means moissanite is very durable and extremely resistant to scratching and abrasion. Additionally, if you believe your moissanite has endured scratching, Charles & Colvard provides a Limited Lifetime Warranty that protects against damage to the stone.

Is moissanite resistant to breaking or chipping?

Yes, moissanite is resistant to breaking and chipping. Moissanite is one of the toughest known gemstones on earth. When placed in high pressure, research has shown that moissanite is highly resistant to breaking and chipping. We have put our gemstones through rigorous testing to ensure you are receiving the highest quality moissanite.

How does moissanite hold up to heat?

Moissanite exhibits a higher level of heat resistance than many other gemstones, including diamonds. When exposed to 2000⁰F heat (a temperature higher than the equivalent intensity of a house fire), moissanite gemstones remained intact and retained their brilliance and fire. Moissanite’s durability and heat tolerance means it is unlikely to sustain damage during jewelry repair.

Why do we expose our gemstones to such demanding tests? Well one, for science! Second, we want to be sure that no matter what situation your moissanite gem is put in, it will always remain as brilliant and beautiful as the day you bought it. Moissanite is one of the hardest and most durable stones on the market today. We stand behind our moissanite products because we believe you deserve to shine brighter than a diamond, no matter what obstacles life throws in your way.
