Is lab grown better than moissanite?

On the Mohs Scale, moissanite gems score a 9.25, while lab grown diamonds receive a 10. Both scores are very good, making each stone well-suited for everyday wear in engagement rings and fine jewelry.

Why is moissanite so cheap?

Fortunately, Moissanite's lower price point is not reflective of its quality. The lower price point is simply a reflection of supply and demand in the engagement ring industry. While we are seeing a shift toward using other gemstones for engagement rings, over 90% of couples are still choosing Diamonds.

How can you tell moissanite from CZ?

Moissanite's dispersion of light is 58% greater than a CZ. Therefore, Moissanite emits more fire, or flashes of rainbow light, than CZ. The luster of Moissanite is 50% higher than that of CZ. The higher the luster, the greater the amount of light reflected from the suface of the gemstone.

Does moissanite look fake?

Moissanite is often compared to diamonds and therefore is often treated as a “fake” diamond or “diamond look-alike” rather than a gemstone in its own right.
