Comparing Diamonds and Moissanites

Engagement Ring Diamond and Moissanite are two gemstones that are oftentimes compared and contrasted because they are both great options for engagement rings. The fact is there are plenty of notable differences that one should know before choosing one over the other. says these differences include color, brilliance, durability, and price. Here are some diamond vs. moissanite comparisons to help you decide.


According to the Mohs Scale of hardness, which is used to measure the durability of minerals, moissanite has a 9.25 score, making it one of the hardest minerals on earth. This fits well for an engagement ring. However, it’s common knowledge that diamond is by far the hardest mineral, with a perfect score of 10. That’s why diamond wins in durability, but moissanite is not at all a bad alternative.


Although colorless, moissanites can still give off a grayish or yellowish hue when exposed to certain lights. The bigger it is, the easier it is to notice these different colors. In contrast, a colorless diamond will never contain traces of colors, whether it is yellow, gray, or brown. This results to its bright and dazzling white appearance, which is loved by people who love its classy look.


Diamonds and moissanites greatly differ in brilliance. Moissanites have fiery, rainbow-like flashes which some love while some hate because of its “disco ball” look especially when exposed to sunlight. On the other hand, diamonds have three ways to reflect light (brilliance, dispersion, and scintillation), which gives it its signature and famous sparkle that everyone loves.
