How is Moissanite Made? Moissanite vs Diamond

Moissanite is a gemstone that is often compared to diamonds. It is made of silicon carbide, which is the same material that makes up diamonds, but it is created in a laboratory rather than mined from the earth.

Moissanite was first discovered in 1893 by French chemist Henri Moissan. He found it in a meteorite that had crashed in Arizona. Moissanite is rare in nature, but it can be created in a laboratory using a process called high-pressure, high-temperature (HPHT) synthesis.

In the HPHT process, silicon carbide powder is placed in a chamber and subjected to high pressure and heat. This causes the powder to crystallize into moissanite. The process takes several weeks to complete.

Moissanite has many properties that are similar to diamonds. It is very hard, with a Mohs hardness of 9.25, which is just slightly less than the hardness of a diamond (10). Moissanite is also very sparkly and refractive, meaning that it reflects and refracts light beautifully.

However, there are some key differences between moissanite and diamonds. Moissanite is slightly less dense than diamonds, so it weighs slightly less for the same carat weight. Moissanite also has a slightly different refractive index, which means that it sparkles slightly differently than diamonds.

Moissanite is often considered to be a good alternative to diamonds because it is more affordable. It is also a good choice for people who are allergic to metals, as moissanite is non-metallic.

Here is a table comparing the properties of moissanite and diamonds:

Property Moissanite Diamond Hardness 9.25 10

Refractive index 2.65 2.42

Density 3.215 g/cm^3 3.51 g/cm^3

Price Less expensive More expensive

Color Colorless to near colorless Colorless to yellow Clarity Very clear Very clear to slightly included

Cut Can be cut into any shape Can be cut into any shape

Ultimately, the best choice for you will depend on your individual needs and preferences. If you are looking for a beautiful and affordable gemstone that is similar to a diamond, moissanite is a good option. If you are looking for the most expensive and rare gemstone, a diamond is the better choice.

Conclusion

Moissanite is a beautiful and affordable gemstone that is often compared to diamonds. It is made in a laboratory using a process called high-pressure, high-temperature (HPHT) synthesis. Moissanite has many properties that are similar to diamonds, including its hardness, refractive index, and sparkle. However, there are some key differences between moissanite and diamonds, such as its density and price. Ultimately, the best choice for you will depend on your individual needs and preferences.
