Diamonds vs Moissanite

Another term that you may encounter more and more is Moissanite, or what we like to refer to as the gemstone from space. Named for its founder, Dr. Henri Moissan, moissanite was first discovered in the remnants of a meteor crater. It’s sparkle and strength were so similar to a diamond that Dr. Moissan, a well practiced gemologist, didn’t realize he had discovered a new gemstone until years later.

Since it’s discovery, moissanite has been found forming naturally on earth, but not in large enough quantities to produce a well-crafted gemstone. For this reason, moissanite gemstones are not only the newest gemstone on the market. Today, all moissanite is lab-grown (and therefore conflict-free) and, in it’s own way, is more rare on earth than diamonds. 


One thing we like to be sure our customers know is that moissanite is not a type of diamond. Some jewelers will market them as moissanite-diamonds, but the two are different stones types. We like to think of moissanite as Diamond’s more brilliant and cost-effective sister. One of the key differences between diamonds and moissanite is their brilliance.

The image above compares the "fire" of a moissanite (on the left) and a diamond (on the right). Fire is a term used by gemologist to determine the brilliance of a stone. As you can see in the image, the moissanite gemstone far out-shines the diamond.

In fact, moissanite is so brilliant that even a poorly cut one can out-sparkle a well-cut diamond. For this same reason, carat (the volume of a diamond) doesn’t exactly translate to moissanite. Instead moissanite is sold by the stones diameter, most often cut to traditional diamond-carat standards.

Durability, wearability, and harness: If you've studied geology you likely recall Mohs hardness scale, the scale on which all stones are graded. Diamonds are notoriously tough, with top marks: 10/10. Moissanite comes in close behind at a 9.25 making it a great diamond substitute or for daily wear.

When it comes to comparing diamonds and moissanite, it is a bit like comparing apples to pears. Very similar, but ultimately they are different gemstones. That said, being man-made, moissanite does not maintain the same re-sell value that a natural diamond will.
