Moissanite vs Diamond: The Ultimate Guide to Choosing Your Perfect Sparkle

When it comes to choosing a gem, especially for something so personal like an engagement ring, most people have the choice between a diamond or moissanite. They are both beautiful and stunning gems, but is one of them better suited for you? Are the two gems equivalent, or are there some striking differences that may affect your choice?

Moissanite and diamonds both share a love for their scintillating brilliance and fire, but both differ in each other's make-up, price, hardness, and overall appeal to beauty.

In this comprehensive guide, we'll cover these distinctions and help you decide which stone is best for your taste, budget, and values. We'll cover everything from where they come from to how they sparkle, price, and durability, so you can feel good about choosing the perfect stone for your event.

Let's dive into the specifics of Moissanite vs. Diamond—and help you find the perfect glint for your ring!

What Is Moissanite?

Moissanite is a naturally occurring gem made of silicon carbide. It was found in 1893 by French chemist Henri Moissan and first discovered in a meteor crater. Moissanite is so rare in nature that a lot of current moissanite is created synthetically. This also makes it an ethical and sustainable alternative to diamonds, which are often produced through mining with enormous environmental and social impact.

The charm of moissanite lies in its fire-like brilliance and durability. Although at first believed to be a form of diamond, moissanite is a different substance with specific physical characteristics. It's commonly appreciated for its rainbow-colored and colorful flashes of light, or "fire," which is brighter than the twinkle of a diamond.

Is Moissanite a Diamond?

Though moissanite is often called a "moissanite diamond," it's actually not a diamond in any way. Why they're confused with each other is that they look extremely alike, though they are made out of something entirely different and come from a different place.

Moissanite actually is far less common naturally occurring than diamonds. Moissanite originally appeared in meteorites, space rocks which fell to Earth. As it only happens rarely, most of the moissanite in the world today is produced artificially using a secret method. That method is melting a silicon carbide powder until it is in a gaseous form and letting a few months pass in which time the gas cools down and solidifies into moissanite. Because of the time and difficulty involved in this process, there are not many moissanite stones created, so they are valuable.

On the other hand, diamonds are formed deep inside the Earth under intense heat and pressure. Lab-created diamonds, however, are grown by simulating these natural processes. There are two main ways of manufacturing lab-created diamonds:

High-Pressure High-Temperature (HPHT): In this process, a small diamond seed is placed inside a chunk of carbon. The carbon is pressurized at high levels and heated to extremely high temperatures. This causes the carbon to melt and form a larger diamond surrounding the seed.

Chemical Vapor Deposition (CVD): A diamond seed is placed inside a sealed chamber, and proprietary gases are introduced into the chamber. The gases are heated to plasma, which deposits pure carbon onto the seed in layers over time to create a diamond.

So, even though both moissanite and diamonds look the same, they consist of different substances and are produced differently. Moissanite is not a diamond, but it is still a beautiful and affordable alternative to diamonds for those who desire something which is similar to a diamond.

Moissanite vs Diamond: Which Is More Expensive?

Price is one of the most significant differences between moissanite and diamonds. Diamonds are typically much more expensive, primarily because of the rarity and the complex mining processes involved in obtaining them. On average, a diamond can cost thousands of dollars per carat, depending on its quality, while moissanite, being lab-grown, is far more affordable.

To put things into perspective, a 1-carat diamond engagement ring can cost anywhere between $2,500 to $20,000, depending on factors such as cut, color, clarity, and carat weight. Meanwhile, a 1-carat moissanite engagement ring will cost roughly $400 to $1,000, making it a much more budget-friendly choice without compromising on sparkle. This price difference is one of the primary reasons people opt for moissanite when looking for an engagement ring that’s stunning yet affordable.

Moissanite vs Diamond: Which Is More Durable?

When it comes to durability, diamonds are the ultimate champion. With a perfect score of 10 on the Mohs scale of hardness, diamonds are the hardest natural material known to man. This means they can withstand scratches and other wear and tear far better than most other gemstones, making them an ideal choice for daily wear, especially in engagement rings.

Moissanite, while not as hard as diamond, is still incredibly durable. Scoring between 9.25 and 9.5 on the Mohs scale, it is second only to diamonds in terms of hardness. This means that moissanite is highly resistant to scratching and will maintain its beauty for years to come, though it may be slightly more prone to scratching than diamonds in extreme cases. Overall, moissanite is a very durable gemstone, but for those who prioritize ultimate hardness, diamonds may be the preferred option.

Moissanite vs Diamond: Which Is More Beautiful?

Beauty is subjective, but in terms of brilliance, moissanite and diamonds each have unique advantages. Diamonds are renowned for their clear, white sparkle, which is a result of their refractive properties. 

The light that enters a diamond bends and refracts in such a way that it creates a dazzling display of white light, often described as "fire." This makes diamonds incredibly eye-catching and desirable.

On the other hand, moissanite is even more brilliant than diamonds. It has a higher refractive index, meaning that it bends and reflects light in a way that creates even more sparkle, with a distinctive rainbow-like effect. This "fire" in moissanite is more intense, making it appear to shine brighter and more vividly than diamonds. 

Some people prefer the colorful flashes of moissanite, while others prefer the classic, white brilliance of diamonds. Ultimately, beauty is in the eye of the beholder.

Budget and Size for Moissanite vs Diamond

One of the major benefits of choosing moissanite over diamond is the price-to-size ratio. Moissanite is far more affordable than diamonds, which allows you to select a larger stone for the same price. 

For example, if you were planning on purchasing a 2-carat diamond, you might have to stretch your budget to upwards of $10,000, depending on the diamond’s quality. In contrast, you could easily afford a 2-carat moissanite ring for a fraction of the price.

For those who want to have a larger, more impressive stone without breaking the bank, moissanite is an excellent option. This allows you to purchase a larger stone without sacrificing your desired size, which is often important for engagement rings. 

This price advantage makes moissanite a popular choice for those seeking an affordable yet beautiful gemstone.

How to Tell the Difference Between Moissanite vs Diamond

It can be challenging to tell moissanite and diamond apart with the naked eye. While both stones are brilliant and sparkle, there are a few key differences. 

Moissanite tends to have more intense flashes of color, especially in bright lighting, while diamonds reflect light in a more subtle and white manner. Under magnification, the two stones can be distinguished by moissanite’s birefringence—a property that causes its facets to appear doubled. Diamonds do not exhibit this effect.

Specialized tools, such as a diamond tester, can also help differentiate between the two. These devices can measure thermal conductivity, which is different in diamonds and moissanite. For most people, however, distinguishing the two without tools can be quite tricky.

Moissanite vs Diamond: Side-by-Side Comparison

Is Moissanite as Good as a Real Diamond?

When it comes to choosing between moissanite and a real diamond, many people wonder if moissanite is "as good" as a diamond. While moissanite offers several similar qualities to diamonds, there are distinct differences that can make one more appealing than the other, depending on your priorities. Let’s break down the factors to consider when comparing these two gemstones to help you decide which one might be the best choice for you.

1. Brilliance and Sparkle:

Both moissanite and diamonds are known for their stunning sparkle, but they differ in how they reflect light. Diamonds are famous for their “fire,” which is the ability to reflect light and create a brilliant, white sparkle. The sparkle in a diamond is often described as clear and subtle.

However, moissanite actually has more brilliance than a diamond. The key difference lies in their refractive index—the measure of how much light bends as it passes through the gemstone. Moissanite has a higher refractive index (around 2.65 to 2.69) compared to diamonds (which have a refractive index of 2.42). This means moissanite sparkles with a rainbow effect, known as "fire," which is more intense and colorful than a diamond's white light. So, if you prefer a gemstone that gives off a vibrant, colorful shine, moissanite could be a better choice.

2. Durability and Hardness:

Diamonds are the hardest natural material on Earth, scoring a perfect 10 on the Mohs scale of hardness. This means that diamonds are extremely resistant to scratches, making them ideal for everyday wear, particularly in engagement rings that are worn constantly.

Moissanite, while not as hard as a diamond, is still incredibly durable. With a score of 9.25 to 9.5 on the Mohs scale, moissanite is one of the hardest gemstones available, second only to diamonds. It is very resistant to scratches and is suitable for daily wear, especially if you are looking for a gemstone that can withstand the test of time without losing its beauty.

3. Price:

One of the biggest advantages of moissanite over diamonds is the price. Moissanite is much more affordable than diamonds, which makes it an attractive alternative for those on a budget. For example, a 1-carat moissanite can cost as little as $500 to $1,000, while a 1-carat diamond might cost anywhere from $2,500 to $10,000, depending on its cut, clarity, and color.

The difference in cost allows you to buy a larger moissanite gemstone for the same price as a smaller diamond. So, if you want a bigger, more noticeable stone without spending as much money, moissanite is an excellent option.

4. Ethical Considerations:

When it comes to ethical concerns, moissanite has the upper hand. Most moissanite on the market is lab-grown, meaning there are no environmental or ethical issues associated with mining. This makes moissanite a more sustainable and responsible choice for those who are concerned about the impact of mining on the environment and communities.

On the other hand, diamonds, especially natural ones, are often associated with harmful mining practices that can damage ecosystems and contribute to labor exploitation. While there are ethical and conflict-free diamond options available, the mining industry as a whole has faced significant criticism for its environmental and human rights impacts.

Lab-grown diamonds offer a more ethical alternative to mined diamonds, but they are still generally more expensive than moissanite.

5. Color:

Diamonds are graded by color, with the best diamonds being completely colorless (grade D). The more colorless a diamond is, the higher its value. However, diamonds can also have slight tints of yellow or brown, which affect their appearance and price.

Moissanite, by nature, tends to have a faint hint of color, especially in larger stones. This can sometimes give it a slightly warmer tone, while diamonds, particularly those of higher grades, are typically cooler and clearer in appearance. However, moissanite's color is usually subtle and is not very noticeable to the naked eye, especially when set in jewelry. Many people find that this slight color difference is hardly noticeable, especially when compared to the advantages of moissanite’s brilliance.

6. Resale Value:

Diamonds generally hold their value better than moissanite. Since diamonds are considered rare, precious, and timeless, they tend to retain their value over time, and some even appreciate in value, especially high-quality diamonds. This is why diamonds are often seen as a long-term investment, and many people expect to sell or pass down their diamond jewelry as heirlooms.

Moissanite, on the other hand, is more affordable, and its resale value is typically much lower. While it is still a valuable gemstone, it is not considered an investment the way diamonds are. The lower cost of moissanite and the fact that it is not as rare as diamonds mean that it doesn’t have the same resale value.

7. Rarity:

Diamonds are rare in nature, which is why they are considered so valuable. The rarity of diamonds is part of their allure, making them the gemstone of choice for engagements, anniversaries, and other significant life events.

Moissanite, although rare in nature, is much more accessible due to its lab-grown availability. Since it is easier and more cost-effective to produce, moissanite is not as rare as diamonds, but it still retains its appeal because of its beauty and affordability.

8. Overall Appeal:

Ultimately, whether moissanite is as good as a diamond depends on what you value most in a gemstone. If you’re looking for an affordable, durable, and brilliant stone with a more colorful sparkle, moissanite is an excellent choice. It offers a lot of beauty for a fraction of the price of a diamond.

However, if you prioritize tradition, the cultural significance of diamonds, or the potential for resale value, a diamond may be the better option for you. Diamonds are also the traditional choice for engagement rings, and their classic, white brilliance is still unmatched by most other gemstones.

Should You Choose a Moissanite Engagement Ring Over a Diamond?

Choosing between a moissanite and a diamond engagement ring depends on personal preference, budget, and values. If you want a larger stone that is more affordable, moissanite is a great choice. It’s also an excellent option for those who are looking for an ethical alternative to mined diamonds. If, however, you are drawn to the timeless allure and tradition of diamonds, a diamond engagement ring might be more suitable.

Ultimately, the best engagement ring is the one that aligns with your style, values, and budget. Moissanite offers an affordable, ethical, and sparkling alternative to diamonds, while diamonds have their own set of timeless qualities. Both stones make excellent choices for engagement rings—what matters most is finding the one that speaks to you.
