Hand wearing gold lab grown diamond jewelry

Diamond jewelry is cherished for its timeless beauty, but natural diamonds can be expensive. If you’re looking for a more budget-friendly option that still dazzles, moissanite and lab grown diamonds are excellent alternatives. However, they’re not quite the same. Moissanite is more affordable than both natural and lab diamonds because it’s not a true diamond. Lab diamonds are real stones made in a controlled environment, offering the same brilliance as mined diamonds but at a lower price.Both options offer a beautiful sparkle, but differences in appearance, durability, and cost can influence your choice. Understanding these differences will help you select the perfect stone for your style and budget, ensuring a choice you will be satisfied with for years.

What Is Moissanite?

Moissanite is a naturally occurring gemstone loved for its stunning brilliance and eye-catching sparkle. It was first discovered in 1893 by a French scientist named Henri Moissan, who found it in a meteorite crater and thought it was a diamond. It turns out it’s made of silicon carbide, a rare mineral.

Because it’s so hard to find naturally, almost all the moissanite you see in jewelry today is lab created. These lab grown gems have the same outstanding qualities as natural moissanite, making them a gorgeous and unique diamond simulant for all kinds of jewelry.

Moissanite and Diamonds: Are They the Same?

Moissanite and diamonds might look similar at first glance, but they’re quite different in terms of what they’re made of and how they look. Whether natural or lab grown diamonds are made of pure carbon, giving them incredible strength and durability. Moissanite is made from silicon carbide—it’s still tough but not quite as hard as diamonds.

When it comes to sparkle, both gems shine beautifully, but in different ways. Moissanite has a fiery, rainbow-like sparkle thanks to its unique refractive properties, while lab grown diamonds offer a classic brilliance almost identical to natural diamonds. This makes lab grown diamonds a go-to choice for people who want a more traditional, timeless look, especially for engagement rings or wedding bands.

Testing for Authenticity: Can Moissanite Pass a Diamond Tester?

Moissanite can sometimes pass as a diamond on basic diamond testers. Non-specialized tools found in retail stores may not always detect the difference between moissanite and real diamonds.

The best way to identify moissanite is by having a jewelry specialist examine the stone through a jeweler’s loupe They can look for key characteristics unique to moissanite, such as its fire, double refraction, and needle-like inclusions, to differentiate it from lab or mined diamonds.

Lab grown diamonds have the same chemical properties as natural diamonds, so they easily pass these tests. Only a skilled professional with a specialized microscope can tell them apart from natural diamonds. Because they’re real diamonds, lab grown diamonds are a great option if you want the look and feel of a diamond without the higher price tag.

Which Is Better? Lab Grown Diamonds or Moissanite

Choosing between mined diamond alternatives, like lab grown diamonds and moissanite, really comes down to what matters most to you. Moissanite offers incredible sparkle at a more budget-friendly price, making it a great choice if you want to save without sacrificing beauty.

However, lab grown diamonds offer the same chemical structure, brilliance, and hardness as natural diamonds, giving them a timeless appeal that moissanite can't fully replicate.

Moissanite vs. Lab Diamonds: Comparing Characteristics

When deciding between moissanite jewelry or a beautiful piece set with lab diamonds, understanding each stone’s qualities can help you make the right choice. Here’s a closer look at how these gemstones compare in terms of durability, sparkle, and cost:

Characteristic Lab Grown Diamonds Moissanite
Durability Lab-grown diamonds are a 10 on the Mohs scale offering unmatched hardness. They are ideal for engagement rings and everyday jewelry. Moissanite rates 9.25 on the Mohs scale, making it highly durable and suitable for everyday wear.
Brilliance Lab grown diamonds exhibit classic diamond brilliance with a refractive index of 2.417-2.419.
They offer a more balanced sparkle, reflecting white light like natural diamonds.
Moissanite has a high brilliance with a fiery, rainbow-like sparkle due to its refractive index of 2.64-2.69.
That extra sparkle can be even more intense in larger stones—some people love it, while others might find it too flashy.
Color Like natural diamonds, lab grown diamonds are available in colorless or various hues, including rare colors like pink, yellow, and blue
Lab stones typically have fewer inclusions than natural stones, which helps prevent cloudiness and maintain their color over time.
Moissanite is usually colorless or almost colorless, but you can find it in teal, grey, and yellow shades. If you’re looking at bigger moissanite gems, remember that their color might change slightly under certain lighting.
Price Lab grown diamonds are up to 60% less expensive than natural diamonds. Their price is influenced by the 4 Cs (cut, color, clarity, carat) and shape, making them a more budget-friendly option for diamond lovers. Moissanite can be more affordable than natural diamonds of similar size, offering a cost-effective option without compromising visual appeal.
Sourcing Lab grown diamonds are created in a controlled environment using high-pressure, high-temperature (HPHT), or chemical vapor deposition (CVD), which are techniques that mimic how natural diamonds form. This makes them an ethical choice compared to mined diamonds. Most moissanite in jewelry is made in a controlled lab setting, using responsibly sourced raw materials, which ensures a clean origin

To keep moissanite sparkling, clean it regularly with mild soap, warm water, and a soft brush to remove oils or dirt. Avoid harsh chemicals or ultrasonic cleaners, as they can damage the stone's surface.

Lab grown diamonds are more durable but still benefit from a gentle cleaning routine. Use a diamond-specific cleaner or mild dish soap and water mix, and scrub gently with a soft toothbrush. Ultrasonic cleaners are generally safe for lab grown diamonds.

Yes, there’s a slight difference in weight! Moissanite is less dense and a little lighter than lab grown diamonds, so if you compare stones of the same size, the moissanite will weigh less. This can make moissanite appear slightly larger for its carat weight, but it's not a huge difference—just something to keep in mind when choosing between the two.

Moissanite and lab grown diamonds are graded differently. Lab grown diamonds are graded like natural diamonds, using the 4 Cs—cut, color, clarity, and carat weight. Moissanite is often assessed based on its color, clarity, cut, and stone size, measured in millimeters.

Many consumers prefer lab created diamonds over moissanite because they offer the same chemical composition, hardness, and classic brilliance as natural diamonds. They provide the authentic diamond experience, making them ideal for those who want the beauty and durability of a diamond at a more affordable price for wedding rings or eternity bands without compromising on quality.
