Diamonds vs Moissanites

When it comes to engagement rings and fine jewelry, diamonds have long been the reigning champion. However, in recent years, a new contender has emerged: moissanites. While they may look similar at first glance, there are some key differences between diamonds and moissanites that are worth exploring. In this article, we will delve into the differences between these two gemstones and help you decide which one is right for you.

What are Diamonds?

Diamonds are one of the most prized and sought-after gemstones in the world. They are made of pure carbon and are formed deep within the earth’s mantle under extreme pressure and heat. Diamonds are known for their incredible hardness, brilliance, and fire, making them a popular choice for engagement rings and fine jewelry.

What are Moissanites?

Moissanites are a relatively new gemstone that was discovered in 1893 by a French scientist named Henri Moissan. They are made of silicon carbide and are grown in a laboratory setting. Moissanites have similar optical properties to diamonds, including brilliance and fire, but are much less expensive than their natural diamond counterparts.

The Differences Between Diamonds and Moissanites

  1. Appearance
    • At first glance, diamonds and moissanites can look very similar. However, moissanites have a slightly different refractive index, which means that they have a slightly different sparkle than diamonds. Moissanites also have a higher dispersion than diamonds, which means that they exhibit more color flashes than diamonds.
  2. Hardness
    • Diamonds are the hardest gemstone on the Mohs scale, with a rating of 10. Moissanites are also very hard, with a rating of 9.25. However, moissanites are more prone to scratching and chipping than diamonds.
  3. Price
    • Diamonds are much more expensive than moissanites, especially if they are high-quality and come with a certificate of authenticity. Moissanites are a more affordable alternative to diamonds, making them a popular choice for budget-conscious couples.
  4. Ethics
    • Diamonds have a controversial history when it comes to ethics, with many diamonds being associated with conflict and human rights abuses. Moissanites, on the other hand, are a more ethical choice, as they are grown in a laboratory setting and do not have the same negative associations as diamonds.


When it comes to choosing between diamonds and moissanites, there is no right or wrong answer. It ultimately comes down to personal preference and budget. Diamonds are a classic and timeless choice that offer unparalleled beauty and value. Moissanites, on the other hand, offer a more affordable and ethical alternative that still offers stunning brilliance and fire. Whether you choose a diamond or a moissanite, what’s most important is that it reflects your personal values and style.
