Moissanite vs. Diamond: Which Sparkles Brighter? – My Blog

If you’re in the market for an engagement ring, you may have come across the term “moissanite.” This popular diamond alternative offers a similar appearance to a diamond but at a much more affordable price. But you may be wondering, does moissanite really look like a diamond? Let’s take a closer look at the similarities and differences between the two gemstones.

Understanding Moissanite

Moissanite is a lab-created gemstone made of silicon carbide. It was first discovered by a French scientist named Henri Moissan in 1893. Today, moissanite is grown in a laboratory and is nearly identical to its natural form. It has a high refractive index, giving it a sparkly and fiery appearance. Additionally, moissanite is very durable, scoring a 9.25 on the Mohs scale of hardness.

Comparing Moissanite and Diamond

When it comes to choosing between moissanite and diamond, there are a few factors to consider.


At first glance, moissanite and diamond can look quite similar. Both stones are clear, white, and sparkly. However, upon closer inspection, there are some subtle differences. Moissanite tends to have a higher level of brilliance and fire, creating more colorful flashes of light. Diamond, on the other hand, has a higher level of luster, which refers to how light reflects off the surface of the stone. Moissanite can also have a slightly different hue, with a slight yellow or green tint, although this is usually only noticeable in larger stones.


Both moissanite and diamond are durable and suitable for everyday wear. However, diamond is slightly harder than moissanite and is more resistant to scratches and chips.


One of the main advantages of moissanite is its affordability. Moissanite is significantly less expensive than diamond because it is lab-grown, whereas diamonds are mined from the earth. This makes moissanite a great option for those who want the look of a diamond without the high price tag. It’s important to note that moissanite is not a “cheap” or “fake” stone but a beautiful gemstone in its own right.

Other Considerations

When choosing between moissanite and diamond, there are a few other factors to keep in mind. For example, if you have a specific shape or cut in mind, you may have more options with diamond. Diamond is also more likely to have imperfections or inclusions that can affect its clarity and value. Additionally, if authenticity is a concern, it’s worth noting that moissanite will not register as a diamond on a diamond tester.

Physical Properties of Moissanite

Moissanite has several physical properties that set it apart from diamonds. It is available in a range of colors, with colorless moissanite being the most popular. Moissanite has a higher refractive index than diamond, meaning it reflects more light and has more brilliance. It can be cut in various shapes and styles, and its carat size ranges from small accent stones to larger center stones. Moissanite is durable, scoring a 9.25 on the Mohs scale, and has excellent clarity and sparkle.

Does Moissanite Look Like a Diamond?

The answer is yes, moissanite can look like a real diamond. Moissanite is designed to mimic the appearance of a diamond and has a similar sparkle and fire. However, there are some differences to consider. Moissanite is made of silicon carbide, while diamonds are made of carbon, which gives them a slightly different sparkle and fire. Additionally, moissanite is not graded based on the 4 Cs like diamonds, but it is still a high-quality gemstone with near-colorless qualities and a high level of sparkle. While moissanite can look like a diamond to the naked eye, a closer examination may reveal some differences in the pattern of sparkles and facets.

Economic Factors to Consider

Budget is often a primary concern when purchasing an engagement ring. Moissanite offers an affordable alternative to diamonds. Moissanite stones are considerably cheaper than diamonds, allowing you to get a larger and more impressive-looking stone for your money. Just remember that moissanite is not a cheap or low-quality stone but a beautiful gemstone in its own right. Be sure to consider factors such as size and quality when comparing prices.

Ethical and Environmental Considerations

When it comes to ethical and environmental concerns, moissanite shines. Unlike diamonds, moissanite is lab-created, which means it has a smaller environmental impact and is free from unethical mining practices. It’s an eco-friendly and ethical choice for those who are conscious of these factors. With its similar appearance to diamonds, moissanite offers a beautiful and affordable alternative that aligns with your values.

Choosing Between Moissanite and Diamond

Ultimately, the choice between moissanite and diamond comes down to personal preference and budget. Consider factors such as appearance, cost, durability, ethics, and other considerations. Both moissanite and diamond are beautiful gemstones that can make stunning engagement rings. The decision is yours to make based on what matters most to you.

In conclusion, moissanite is a great alternative to diamonds for those who want a beautiful and affordable gemstone. While it may not be a perfect match to a diamond, it possesses its own unique sparkle and beauty.
