The selection between moissanite and diamond is one of the most frequent ones that jewelry consumers have to make. Although each stone is distinctive in its own way, there are some significant variations that could influence your choice. Knowing how moissanite varies from diamond can help you make an informed decision and get the most bang for your buck. To help you shop with confidence, we'll go over these differences in this blog post.

What Is Moissanite?

Moissanite is a gemstone composed of silicon carbide and is known for its brilliance and fire. Moissanite is actually a lab created gemstone, and its production involves a complex process of growing crystals in a controlled environment. The exceptional hardness of moissanite is one of its most distinguishing features.

On the Mohs scale of mineral hardness, moissanite ranks at 9.25, making it one of the hardest gemstones available. This means that moissanite is perfect for everyday use because it is so long-lasting and resistant to scratches.In terms of its appearance, moissanite has a unique sparkle that is often compared to that of a diamond.

Due to its high refractive index, it reflects light well and produces a lot of sparkle. Additionally, because moissanite disperses light into its constituent hues and has a high internal fire, it exhibits a stunning play of color.

The History Of Moissanite

Moissanite was first discovered by Henri Moissan in 1893 while he was examining a meteor crater in Arizona. At first, Moissan thought he had discovered diamonds, but after further analysis, it was determined that the crystals were actually a new mineral, which was later named moissanite in his honor.

For many years, moissanite remained a rarity due to its natural occurrence in small quantities. However, in the latter half of the 20th century, researchers were able to manufacture moissanite in a lab setting. This lab-created moissanite is now widely available and has gained popularity as a diamond alternative.

Moissanite vs Diamond What’s The Difference?

Composition and Origin

One of the most popular and sought-after jewels in the world is the diamond. They are made of carbon and are created under incredibly high pressure and heat deep inside the Earth's mantle. Diamonds are a classic option for engagement rings and other fine jewelry because of their outstanding hardness and brilliance.

One of the main differences between moissanite and diamond is their origin. While moissanite is lab-created, diamonds are formed naturally over millions of years. This distinction can have an impact on the price, as natural diamonds are generally more expensive than moissanite.

Hardness and Durability

Another key difference between the two is their hardness. Diamonds are the hardest substance on Earth, ranking at 10 on the Mohs scale. This means that they are extremely resistant to scratching and can maintain their luster and beauty for a lifetime.

Moissanite, on the other hand, ranks at 9.25 on the Mohs scale, making it slightly less hard than a diamond. While still very durable, moissanite may be more prone to scratching over time.

Brilliance, Fire, and Sparkle Differences

When it comes to sparkle and brilliance, both moissanite and diamonds have their own unique qualities. Diamonds are known for their exceptional brilliance, which is a result of their high refractive index. This means that they reflect light very well, creating a dazzling display of sparkle.

Moissanite, on the other hand, has an even higher refractive index, which means that it can actually create more sparkle than a diamond. This is one of the reasons why moissanite is often referred to as a "fire gem" due to its ability to disperse light into its component colors, creating a stunning play of color.

Color and Clarity

In terms of color, diamonds are graded on a color scale from D (colorless) to Z (light yellow or brown). The most highly valued diamonds are those that are colorless or near colorless.

Moissanite, on the other hand, is generally considered a near-colorless gemstone, with a slight yellow or green tint. However, the difference in color between a moissanite and a diamond is often very subtle and may not be easily noticeable to the untrained eye.

Cost and Value

Price is another factor to consider when deciding between moissanite and diamond. As mentioned earlier, moissanite is generally more affordable compared to diamonds. This is mainly due to the difference in their origin, with diamonds being naturally formed and much rarer. However, it's important to note that the price of both moissanite and diamonds can vary depending on factors such as carat weight, cut, clarity, and color.

Shapes and Sizes

There are numerous shapes and sizes available for both moissanite and diamonds. As well as more unusual and fascinating shapes like pear, marquise, and heart, diamonds are also available in more conventional shapes like round, princess, and emerald. Additionally, a variety of forms are available in moissanite, such as the widely-liked round brilliant cut as well as cushion, oval, and radiant cuts.

Does Moissanite Show Refraction?

Yes, moissanite does show refraction. Since moissanite has a higher refractive index than diamonds, it can divide light into its individual colors, producing an exquisite play of color. This is one of the reasons moissanite is frequently called a "fire gem" and is renowned for having more glitter than a diamond. The gemstone moissanite is unquestionably an excellent option if you're seeking for something with outstanding light refraction.

What Are The Benefits Of Buying Moissanite Instead Of Diamond?

  1. Cost Savings: Moissanite is generally more affordable compared to diamonds, allowing you to get a larger gemstone for your budget. This means you can have a more substantial piece of jewelry without breaking the bank.
  2. Ethical Alternative: Moissanite is created in a lab, making it an ethical choice for those concerned about the environmental and social impact of diamond mining. By choosing moissanite, you can enjoy a beautiful gemstone without contributing to the negative aspects of the diamond industry.
  3. Durability: Moissanite is an extremely durable gemstone, ranking just below diamonds on the Mohs scale of hardness. The resistance to scratches, chips, and cracks makes it perfect for regular wear and ensures that your jewelry will survive for years.
  4. Brilliant Sparkle: Moissanite has a higher refractive index than diamonds, giving it superior light dispersion and creating a stunning play of colors. This means moissanite jewelry can have more brilliance and fire than a diamond, making it a captivating alternative for diamond lovers.
  5. Wide Range of Shapes and Sizes: Just like diamonds, moissanite is available in a variety of shapes and sizes. Whether you prefer the classic round brilliant cut or a more unique shape like a cushion or oval, moissanite offers a wide range of options to suit your personal taste and style.

Will Moissanite Pass a Diamond Test?

Yes, Moissanite will pass a diamond test. The thermal and electrical conductivity traits of Moissanite resemble those of diamonds, which are extensively utilized in diamond testers. As a result, subjecting Moissanite to a diamond tester frequently results in a positive indication, suggesting its similarity to a diamond.


In conclusion, when it comes to potential alternatives for diamonds, moissanite is an excellent option for a number of reasons. It is long-lasting, can be sourced in an ethical manner, has a bright brilliance, and is available in a diverse array of shapes and dimensions. In addition, due to the fact that moissanite and diamond have comparable qualities, it can even pass a diamond test. Therefore, you should consider moissanite if you're seeking for a gemstone that is beautiful and within your budget.
