Moissanite and Other Lab-Created Gems

Moissanite and Other Lab-Created Gems: A Comparison of Popular Synthetic Gemstones

With growing interest in ethical and sustainable gemstones, lab-created options have become increasingly popular. Among these, moissanite stands out as a popular choice for those seeking an alternative to diamonds. In this blog post, we will discuss how moissanite compares to other lab-created gemstones such as cubic zirconia and lab-grown diamonds, focusing on their properties, appearance, and overall appeal.

Moissanite: Beauty and Brilliance

Moissanite, originally discovered in meteorites and now produced in laboratories, is known for its exceptional brilliance, fire, and luster. With a hardness of 9.25 on the Mohs scale, it is an incredibly durable gemstone suitable for everyday wear. Moissanite is available in various cuts and colors, and its affordability makes it a popular choice for those seeking luxury at a more accessible price point.

Cubic Zirconia: A Budget-Friendly Option

Cubic zirconia (CZ) is another popular lab-created gemstone known for its affordability and diamond-like appearance. With a hardness of 8.0-8.5 on the Mohs scale, CZ is relatively durable, but it is more prone to scratching and wear over time compared to moissanite and lab-grown diamonds. CZ has excellent fire and brilliance, but it lacks the depth and luster of moissanite and diamonds.

Lab-Grown Diamonds: The Closest to Natural Diamonds

Lab-grown diamonds, also known as synthetic or cultured diamonds, are created using advanced technology that replicates the natural conditions under which diamonds form. These diamonds are chemically, physically, and optically identical to their natural counterparts, with the primary difference being their origin. Lab-grown diamonds have the same hardness as natural diamonds (10 on the Mohs scale), making them incredibly durable. While lab-grown diamonds are more affordable than natural diamonds, they are typically more expensive than moissanite and cubic zirconia.

Comparing Moissanite, Cubic Zirconia, and Lab-Grown Diamonds

  1. Hardness and Durability: Moissanite is more durable than cubic zirconia but slightly less so than lab-grown diamonds. While all three gemstones are suitable for everyday wear, moissanite and lab-grown diamonds offer greater longevity and scratch resistance.

  2. Brilliance and Fire: Moissanite is renowned for its exceptional fire and brilliance, surpassing both cubic zirconia and lab-grown diamonds in this regard. While cubic zirconia has impressive fire and brilliance, it lacks the depth and luster of moissanite and diamonds.

  3. Price: Moissanite offers an excellent balance between affordability and luxury, providing a high-quality gemstone at a more accessible price point than lab-grown diamonds. Cubic zirconia is the most budget-friendly option, but its lower durability and luster make it less desirable for some.

  4. Ethical and Environmental Considerations: All three lab-created gemstones provide an ethical and sustainable alternative to natural diamonds, which can be associated with negative social and environmental impacts. However, moissanite and lab-grown diamonds offer superior durability and longevity, making them a more sustainable choice in the long run.

  5. Versatility: Moissanite, cubic zirconia, and lab-grown diamonds are all available in various cuts, colors, and settings, providing ample options for those seeking a lab-created gemstone. Moissanite's unique fire and brilliance make it particularly well-suited for vintage-inspired and minimalist designs.


In conclusion, when comparing moissanite with other lab-created gemstones like cubic zirconia and lab-grown diamonds, it's crucial to weigh factors such as hardness, durability, brilliance, fire, price, and ethical considerations. Moissanite stands out as an excellent balance of beauty, durability, and affordability, making it a popular choice for those seeking an ethical and sustainable alternative to diamonds. Ultimately, the decision between moissanite, cubic zirconia, and lab-grown diamonds will depend on individual preferences and priorities, with each gemstone offering its unique set of benefits and appeal.
