Our Stone

The stone used in the Desert Diamonds Collection is a superior quality diamond simulant that looks and behaves just like a diamond in terms of its brilliance, fire and longevity. It is hand cut using the same technique as a diamond but there is one distinct difference – the price!

We use the highest grade diamond simulants available on the market today, which are sourced specially for our product. The diamond simulant used in the Desert Diamonds Collection is rated 8.5 on the MOHS scale of hardness compared to a diamond which, with a rating of 10, is the hardest natural substance.

Carat Size Information Chart

Carat is a widely accepted measurement of gem weight.  Diamond simulants such as those used in Desert Diamonds jewelry are heavier than natural carbon diamonds due to their chemical composition.  Therefore a 1ct diamond simulant will look smaller than a 1ct carbon diamond.  Diamond size does not increase proportionally with their carat weight.

To make a visual comparison between diamond simulants and carbon diamonds, it is easier to use dimensions in millimeters as a point of reference.

As an example, a 1.75ct round brilliant diamond simulant has a diameter of 6.5mm and appears the same as a 1ct carbon diamond.
