Lab-Grown Diamonds vs Moissanite: Which is Better?

Lab-Grown Diamonds vs Moissanite: Which is Better?

In recent years, there has been a surge in interest in alternative options for traditional, mined diamonds. Two of the most popular alternatives are Lab-Grown Diamonds and Moissanite. Both of these gemstones offer unique benefits and appeal to different types of buyers. In this article, we will compare Lab-Grown Diamonds and Moissanite to help you determine which is the better choice for your needs.

Formation and Composition

Lab-Grown Diamonds: Lab-Grown Diamonds are created using advanced technology that replicates the natural process of diamond formation. They are made of pure carbon atoms arranged in a crystal lattice structure, just like natural diamonds. Lab-Grown Diamonds have the same physical, chemical, and optical properties as mined diamonds.
Moissanite: Moissanite is a gemstone made of silicon carbide. It was first discovered in a meteorite by Dr. Henri Moissan in 1893, which led to its name. Today, Moissanite is created in laboratories and is known for its impressive sparkle and brilliance. While it is visually similar to diamonds, its chemical composition and crystal structure are different.

Appearance and Brilliance

Lab-Grown Diamonds: Lab-Grown Diamonds possess the same sparkle, fire, and scintillation as natural diamonds, making them virtually indistinguishable from their mined counterparts. They are available in a variety of shapes, sizes, and colors, allowing for a wide range of customization options.
Moissanite: Moissanite is known for its exceptional brilliance and fire, which often exceeds that of diamonds. This is due to its high refractive index and dispersion properties. However, some people may find Moissanite’s intense sparkle to be too flashy or artificial-looking compared to diamonds.

Hardness and Durability

Lab-Grown Diamonds: Lab-Grown Diamonds have a hardness of 10 on the Mohs scale, making them the hardest known material. This means they are highly resistant to scratches and daily wear, making them an ideal choice for engagement rings and other jewelry pieces meant to last a lifetime.
Moissanite: Moissanite has a hardness of 9.25 on the Mohs scale, which is slightly less than that of diamonds. While it is still a durable option for everyday wear, it is not as scratch-resistant as diamonds.


Lab-Grown Diamonds: Lab-Grown Diamonds are generally more affordable than mined diamonds, often costing 20-40% less. This price difference is due to the lower production costs and a more efficient supply chain.
Moissanite: Moissanite is significantly less expensive than both mined and Lab-Grown Diamonds, making it an attractive option for budget-conscious buyers. The price difference can allow for larger stones or more intricate designs without breaking the bank.

Ethical and Environmental Considerations

Lab-Grown Diamonds: Lab-Grown Diamonds offer an ethical and environmentally-friendly alternative to mined diamonds, as their production does not involve mining or the associated negative social and environmental impacts. Additionally, Lab-Grown Diamonds are typically sourced from conflict-free zones, ensuring a more ethical supply chain.
Moissanite: Moissanite is also an ethical and eco-friendly choice, as its production does not involve mining or contribute to environmental degradation. Like Lab-Grown Diamonds, Moissanite is created in laboratories, which allows for greater control over the supply chain and ethical sourcing practices.

Market Acceptance and Resale Value

Lab-Grown Diamonds: The market for Lab-Grown Diamonds has grown significantly in recent years, with more jewelers and consumers embracing this alternative. However, it is essential to note that Lab-Grown Diamonds tend to have a lower resale value compared to mined diamonds due to the lower demand in the secondary market.
Moissanite: While Moissanite has gained popularity as an affordable and ethical diamond alternative, it has not yet achieved the same level of market acceptance as Lab-Grown Diamonds. Its resale value is also generally lower than that of diamonds, as it is considered a distinct gemstone with a different market demand.

Certification and Grading

Lab-Grown Diamonds: Lab-Grown Diamonds can be certified and graded by reputable gemological laboratories, such as the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). These certifications provide assurance of the diamond’s quality, grading, and authenticity, making it easier for consumers to make informed decisions.
Moissanite: Moissanite can also be certified by gemological laboratories, but the grading system is different from that of diamonds. Moissanite is usually graded based on its color, clarity, and cut, but the grading scales are not directly comparable to diamond grading scales. This can make it more challenging for consumers to assess the quality of a Moissanite stone.

In conclusion, choosing between Lab-Grown Diamonds and Moissanite depends on your priorities, budget, and personal preferences. If you value the appearance, durability, and prestige associated with diamonds but want a more ethical and affordable option, Lab-Grown Diamonds may be the right choice for you. On the other hand, if you’re looking for a budget-friendly and ethical alternative with exceptional brilliance and fire, Moissanite could be the perfect gemstone for your needs.

Both Lab-Grown Diamonds and Moissanite offer unique benefits, and neither is inherently “better” than the other. By carefully considering the factors discussed in this article, you can make an informed decision that best aligns with your values and preferences, ensuring that your chosen gemstone will be cherished for years to come.
