What is Diamond Simulant?

Before we get to the difference between Asha and Nexus diamond, let’s first find out what exactly are diamond simulants. A simulant simply means a thing that resembles something else in appearance. In this case, a diamond simulant can be another crystal that looks like a diamond but doesn’t have the physical properties of a diamond. You can consider these as diamond alternatives.

What is Asha Diamond Simulant?

An Asha diamond simulant is lab-created to look exactly like a real diamond. The material is chosen to make this is cubic zirconia, which is layered using a treatment to protect it from damage.

The protective layer is composed of the same atoms as found in real diamonds. This layer adds a brilliant shine and luster to the stimulant so that it looks like the original gemstone.

However, this process doesn’t end here. This hybrid stone also goes through an amorphous diamond treatment. This treatment hardens the Asha diamond stimulant’s top layer and also makes it non-porous so that it doesn’t become dull and cloudy over time.

It is very helpful in making it as hard and real-looking as a diamond. On the Mohs hardness scale, the rating of the Asha diamond is usually about 9.8 which is just two points less than the real diamond’s. This ensures the hybrid stone’s durability as well as making it highly scratch-resistant.
