How Much is a 1 Carat Moissanite Worth?

— by Cullen Jewellery — Reading time 4 minutes

Beautiful, long-lasting and extremely durable, moissanite is a gemstone that is rapidly rising in popularity. While moissanite is a white gemstone like a diamond, it has a distinct and unique sparkle that gives off more of a rainbow appearance compared to the crisp white, grey and blue sparkle of a diamond. Its more affordable price point and unique sparkle make it appealing to those who are wanting something different for their engagement ring stone. But how much is a moissanite stone actually worth? Read on to find out!

What’s All the Fuss About Moissanite?


Moissanite is a beautiful, extra sparkly gemstone that is quickly gaining recognition in Australia and globally for its incredible similarities to a diamond. While it is its own unique gemstone with its own properties, it has a comparable sparkle and colour to a diamond with a few subtle differences that often see it confused with diamonds to the naked eye.

With a 9.25 hardness rating on the Moh’s hardness scale, moissanite is the second-hardest gemstone in existence, second only to a diamond which sits at a 10. This means a moissanite stone is incredibly durable, highly resistant to scratches and able to survive a lifetime of daily wear without ever losing its sparkle. Aside from diamonds, moissanite is more durable than almost every other type of gemstone, including rubies, sapphires, and emeralds.

Compared to diamonds which reflect light in a crisp, dense faceting pattern with a greater proportion of white, grey and blue light, moissanite sparkles with a rainbow-coloured fire due to its different refractive index. While diamonds remain the popular choice for engagement rings, those who prefer more of a rainbow sparkle may find themselves gravitating towards moissanite.

As a lab created stone, moissanite costs a fraction of the price of a mined diamond with the same properties. Despite the attractive price tag, it’s understandable if you’re hesitant to rush into purchasing a moissanite engagement ring – it almost sounds too good to be true!

Carat Weight/size


Since moissanite weighs a little less than a diamond of the same size due to its lower density, moissanite is measured in millimeters rather than carat weight. When compared to a diamond of the same size, moissanite may measure differently in weight but it will measure close to or the same in diameter, so it is always an approximate carat weight.

Cost Comparisons


Depending on the stone’s carat size and distinct specifications, you can expect to make significant savings by purchasing a moissanite over a diamond. Ultimately the choice between the two comes down to personal preference and budget.
