Moissanite Is Not A Diamond, But Is Equally As Luminous

Moissanite is a type of gemstone that looks like a diamond–it has the brilliance and clarity of one, but this gem comes from the stars. It gets its name from the French scientist, Henri Moissan, who won the Nobel Prize in Chemistry. He studied the mineral that was found in a crater that was created by a meteorite in Arizona. He thought he’d found diamonds, but upon further examination, the gem had silicon carbide particles.


Natural Moissanite is very, very rare so it’s often lab-created. The ability to recreate these gems in a laboratory came after several years of trial and error but eventually, the particles that Moisson found were synthesized to produce this beautiful gemstone.

While some may lean towards the idea that lab-created gemstones are fake or not good enough as the natural stuff, I think it’s beautiful how we can create gems exactly down to the molecular structure. Some may call it fake, I call it art. The gem you see in the photos is one that I obtained from Giga Jewe and it came from China. It took about two months to get to me.


The gem specifically is a white D color Moissanite with a Marquise cut.  According to Giga Jewe my gem, 2.4 mm, weighed a tenth of a carat (.1 ct) which is fine by me because I wanted this for my collection–not to work with.

Moissanite has a hardness of 9.3, brilliance of 2.65, and a specific gravity of 3.22. In comparison, Diamonds have a hardness of 10, brilliance of 2.42, and a specific gravity of 3.52–I get this information from the pamphlet that was provided by Giga Jewe.


Moissanite is a gemstone that has been created to be similar to a diamond, but these gems are very different from one another. Moissanites exhibit a fiery rainbow flash that Brilliant Earth notes resemble a disco ball in the sun whereas diamonds reflect the light back in three different ways–simultaneously.
