Moissanite vs Lab Diamond: Which is More Valuable?

As moissanite and lab diamonds are becoming a more popular choice for engagement rings, in this blog we are going to cover the differences and similarities between them!

Let’s begin with what are moissanites and lab diamonds are. A moissanite is a gemstone, being the second hardest mineral in nature after diamond. Then a lab diamond are diamonds which are grown in a lab.

What is Moissanite?

Moissanite is a naturally occurring mineral that was first discovered in 1893 by a French scientist named Henri Moissan. It is a rare mineral that is found in meteorites, but most moissanite used in jewelry today is lab-created. Moissanite has a higher refractive index than diamonds, which means that it can sparkle more and appear more brilliant in certain lighting conditions. It is also less expensive than diamonds and is often used as a diamond alternative in engagement rings and other jewelry.

What is a Lab Diamond?

Lab-grown diamonds, on the other hand, are created in a laboratory using advanced technology that mimics the conditions under which diamonds form in the earth's crust. These diamonds are chemically and physically identical to natural diamonds and have the same optical and physical properties as natural diamonds. The only difference is that lab-grown diamonds are created in a controlled environment, rather than being formed naturally over millions of years.

What Are the Differences Between Moissanite vs Lab Diamond?

Moissanite and lab-grown diamonds are both popular alternatives to natural diamonds in the jewelry industry. While they may look similar at first glance, there are some key differences between moissanite and lab-grown diamonds that you should consider before making a purchase.
