Moissanite vs. Diamond

Moissanite vs. Diamond

* 1. Durability

Gemstones are measured on the Mohs Scale of Hardness, which assesses a gem’s ability to withstand surface scratching.

On the Mohs scale: 

Moissanite gemstones are a 9.25 on the Mohs Scale of Hardness, so they are suitable for everyday wear.

Diamonds are the hardest known mineral and receive a 10 on the Mohs Scale of Hardness. Because of this exceptional score, diamonds are very durable and ideal for everyday wear. This contributes to their popularity as engagement rings’ center gemstones.

* 2. Brilliance

Brilliance refers to the appearance of light reflected from the interior of the gem.

Moissanites exhibit a different kind of brilliance than diamonds do, as their faceting pattern is different. The fiery, rainbow flashes emitted by moissanites are beloved by some, but others feel that moissanite’s heightened brilliance can create a “disco ball” effect, especially in sunlight. The bigger the moissanite, the more likely it is that the difference will be noticeable. Moissanite has a refractive index from 2.65 – 2.69, which is higher than a diamond.

A different type of brilliance is what makes it possible to distinguish a moissanite from a diamond. Diamonds reflect light in three different ways. The white light reflected back is referred to as brilliance, while the rainbow of colors refracted through the diamond is referred to as dispersion. The surface sparkle of a diamond, known as scintillation, is a third type of diamond light return. The combination of these three gives diamonds their famous sparkle.

* 3. Color

Color is the natural color or lack of color visible within a gemstone.

While moissanites are labeled as “colorless”, the gems can still project a yellow or grayish hue in certain lights. Here again, the larger the moissanite, the more noticeable the color.

A colorless diamond, whether natural or lab created, has a natural body color that contains no traces of yellow, brown, or grey, resulting in a dazzling, bright white appearance.

* 4. Price

For the same size from the top view, moissanites are dramatically lower in pricing than diamonds of that size. Moissanite gems typically vary in price only based on size and whether the stone is Premium or Super Premium.

Natural diamonds and lab created diamond prices vary based on shape, carat, cut, color, and clarity. Lab created diamonds are more affordable than natural diamonds.

* 5. Sourcing

 Because moissanites are lab created, they are an appealing option for those seeking an eco-conscious gemstone as they require no mining.

Diamonds that have been selected for their ethical and environmentally responsible origins, as well as lab created diamonds that are ethically grown with minimal environmental impact.
