Both lab-grown diamonds and moissanite are celebrated for their sparkle and sustainability, which has led many people to ask: is moissanite a lab-grown diamond? How are the two different?
Each of these two gemstones holds unique properties that make them a standout in modern jewellery. As jewellery enthusiasts seek ethical and affordable alternatives to traditional gems, understanding the nuances between these two brilliant stones has never been more crucial.
Whether you’re considering purchasing a pair of lab-diamond earrings or are intrigued by the allure of a moissanite ring, it’s important to understand the differences between moissanite vs lab diamonds. Armed with this information, you can be certain that you’re choosing the perfect gemstone for your jewellery.
A quick refresher on lab-grown diamonds
Before we compare moissanite vs lab diamonds, it’s important to first understand the differences between lab-grown diamonds vs natural diamonds.
Lab-grown diamonds, also known as synthetic or cultured diamonds, are genuine diamonds created in a controlled laboratory environment, mimicking the natural process of diamond formation. These diamonds are cultivated using advanced technological processes such as High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD). In these methods, a carbon seed is exposed to high temperatures and pressures or a carbon-rich gas mixture, respectively, causing carbon atoms to gradually accumulate and crystallise around the seed. This process mirrors the natural growth of diamonds beneath the Earth's surface, creating stones that possess the same chemical composition, crystal structure, optical properties and physical characteristics as mined diamonds.
Lab-grown diamonds offer an ethically and environmentally sustainable alternative to traditionally mined diamonds, as they reduce the impact of mining on the earth and often come with a smaller carbon footprint. Their production also ensures a conflict-free origin, making them an increasingly popular choice for consumers seeking both luxury and responsibility in their jewellery choices.

What is moissanite?
Moissanite is a striking gemstone known for its exceptional brilliance and durability, originally discovered in 1893 by French scientist Henri Moissan in a meteor crater. This rare, naturally occurring mineral, also known as silicon carbide, is almost as hard as diamonds, scoring 9.25 on the Mohs scale of mineral hardness, making it highly resistant to scratches and abrasions.
Due to its scarcity in nature, almost all moissanite used in jewellery today is synthetically grown in laboratories. These lab-created moissanite stones exhibit a fiery, rainbow-like sparkle that often exceeds that of diamonds, making them a visually captivating and cost-effective alternative.
Not only is moissanite valued for its aesthetic appeal, but it is also prized for its ethical and sustainable attributes, as its lab-grown nature ensures minimal environmental impact. This gemstone has gained popularity among those who seek a durable, beautiful and ethical alternative to traditional gemstones, offering a unique blend of beauty and conscientiousness in the world of fine jewellery.
Now how do these differ from lab-grown diamonds?
While both lab-grown diamonds and moissanite are stunning and sustainable options for fine jewellery, they have distinct differences that set them apart in terms of sparkle, colour, refraction, hardness, price and overall appearance.
Sparkle
The sparkle of a gemstone, often referred to as its "fire," is a key differentiator. Lab-grown diamonds exhibit a balanced sparkle that includes brilliance (white light) and dispersion (coloured light). Moissanite, on the other hand, is known for its exceptional fire, displaying a more intense and colourful sparkle. This heightened fire can produce a dazzling rainbow effect, which is more pronounced in moissanite than in diamonds.
Colour
Lab-grown diamonds are available in a range of colours, from colourless to slightly yellow or brown, similar to their natural counterparts. They are graded on a scale from D (colourless) to Z (light colour). Moissanite typically has a slight yellow or greyish hue, especially in larger stones or under certain lighting conditions, though newer versions are increasingly colourless.
Refraction
Refraction, or the bending of light as it passes through a gemstone, affects its brilliance. Diamonds have a high refractive index, but moissanite has an even higher one. This means that moissanite can exhibit more brilliance than diamonds, though the pattern of light dispersion is different, with moissanite showing more colourful flashes of light.
Hardness
Hardness is a measure of a gemstone’s resistance to scratching. On the Mohs scale, diamonds are the hardest known mineral, rated a perfect 10. Moissanite is close behind, rated at 9.25, which is still exceptionally hard and suitable for everyday wear.
Price
Price is often a significant deciding factor for many buyers. Generally, moissanite is much more affordable than lab-grown diamonds. This price difference is due to the rarity and the more complex production process of lab-grown diamonds compared to moissanite.
Appearance
While at first glance, moissanite and lab-grown diamonds may seem similar, subtle differences exist. Only experts with specialised equipment can reliably tell them apart. To an untrained eye, distinguishing between the two can be challenging due to their similar appearance. Both stones are brilliant and clear, but moissanite's unique sparkle and fire can sometimes give it away to an observer familiar with gemstones.
Some other alternatives to diamonds
While lab-grown diamonds and moissanite are popular choices, there are other gemstones that also serve as appealing alternatives to traditional diamonds, including

Cubic zirconia
A common misconception is that lab-grown diamonds are cubic zirconia. However, there are some major differences between cubic zirconia vs lab-grown diamonds.
Cubic zirconia (CZ) is a synthetic crystalline substance used as an affordable alternative to diamonds. Widely known for its durability and low cost, cubic zirconia scores an 8-8.5 on the Mohs scale of hardness, making it a reasonably hard and scratch-resistant material. It is almost optically flawless and can be made entirely colourless, resembling the D grade on the diamond colour scale.
However, one of the key differences between cubic zirconia and diamonds is in their brilliance and fire. While CZ can mimic the initial look of a diamond, it has a higher dispersion rate, resulting in more rainbow-like light reflections and less white light brilliance.
White sapphires
White sapphires are a natural and transparent variety of sapphire, and they serve as a subtle and elegant diamond alternative. Ranking a 9 on the Mohs scale, they are just one step below diamonds in terms of hardness, ensuring good durability for everyday wear.
Unlike diamonds, which are prized for their brilliant sparkle, white sapphires offer a more understated and less refractive appearance. They tend to exhibit less brilliance and fire, often displaying a more subdued, icy look. This can be particularly appealing to those who prefer a less flashy aesthetic but still want a gemstone with durability and natural origin. White sapphires are typically more affordable than diamonds but can be more expensive than some other alternatives like cubic zirconia.
