Will Moissanite Last Forever?

This is one of the most common questions from people considering a moissanite engagement ring. They worry that moissanite will not have the same durability or lifetime sparkle of a diamond ring. However, moissanite is very similar to diamonds in this sense, and we are so confident that your ring will last forever that all of our moissanite comes with a lifetime guarantee. Here is why we know your moissanite will sparkle just as brightly in fifty years.

A gem’s hardness and scratch resistance is measured by the Mohs Scale which gives each precious gem a mark out of ten. Diamonds are the most durable, with a score of 10. Moissanite are just behind that with a mark of 9.25, making it the second hardest and most durable gem. For comparison, emeralds are an 8 and rubies are a 9 on the Moh Scale, so moissanite is definitely a good choice if a gem’s durability is important to you. This means that it is extremely unlikely that your moissanite will be scratched unless your store it with diamond jewellery.

In general, the colour, clarity and sparkle of a moissanite will never change over time. Some gems will cloud over time, robbing the jewellery of its sparkle. The only thing that can cause moissanite stones to cloud slightly is exposure to certain chemicals or dirt and grime, so it is advisable to take your moissanite engagement ring off before you undertake cleaning activities or working with chemicals. However, this is only temporary and can be fixed with targeted cleaning, either completed by yourself or through a professional, which will leave your moissanite ring as sparkly and shiny as ever.

The harder a gem is, the more scratch-resistant it is, and sitting at a 9.25 on MOHs hardness scale Moissanite is extremely scratch-resistant. But like any other gemstone, it is not indestructible and can potentially be susceptible to damage from an impact. Interestingly, moissanite does not have cleavage planes, which are weaker sections of the stone that have a chance of splitting or cracking if the gemstone is impacted. Moissanite's lack of cleavage planes means it is uniformly strong throughout the surface of the gem. However, it is advisable that you take your moissanite ring off if you plan to do any physical activity. Some cuts of moissanite such as princess and marquise cuts will be slightly more susceptible to impact because of the shape of the stone.
