Moissanite vs Lab Diamond

When it comes to choosing the perfect gemstone for an engagement ring or other jewelry pieces, moissanite and lab grown diamonds have been gaining popularity in recent years. They offer a more affordable and ethical alternative to natural diamonds while still radiating beauty and brilliance. In this article, we'll delve into the world of moissanite vs lab diamond, comparing their properties, origins, and value to help you make an informed decision for your next jewelry purchase.

What is Moissanite?

Moissanite is a dazzling gemstone that originated from space! In 1893, a scientist named Henri Moissan discovered tiny particles of this gem in a meteor crater, mistaking it for diamonds initially. This gemstone is composed of silicon carbide and shares many visual similarities with diamonds. It has a high refractive index, which means it disperses light better than most gemstones, resulting in a brilliant sparkle.

Lab Diamonds: The Sparkling Creations

Lab grown diamonds, as the name suggests, are diamonds created in a controlled environment, replicating the natural diamond formation process. They are chemically and physically identical to natural diamonds but are much more affordable. Lab diamonds offer a conflict-free and environmentally-friendly alternative, making them an attractive option for conscientious consumers.

Difference between Moissanite vs Lab Diamond

Here's a comparison table showcasing the differences between Moissanite and Lab-Grown Diamond

Feature Moissanite Lab-Grown Diamond

Market Availability Widely available Increasingly available in the market
Popularity Gaining popularity as a diamond alternative Growing in popularity for ethical and eco-conscious reasons
Uniqueness Unique gemstone with its own brilliance and fire Each lab-grown diamond is unique, just like natural diamonds



The 4 C's Comparison: Clarity, Color, Cut, and Carat


Both moissanite vs lab diamond have excellent clarity. Moissanite, being a silicon carbide gem, is created in a way that results in minimal inclusions, making it nearly flawless to the naked eye. Lab diamonds also boast high clarity levels, with minimal imperfections due to their controlled growth environment.


In terms of color, moissanite has a natural icy white appearance, which is highly sought after. On the other hand, lab diamonds offer a wide range of colors, similar to natural diamonds. You can find lab diamonds with varying color grades, including the popular "D" grade, which represents a colorless diamond.


Both moissanite and lab diamonds can be expertly cut to reflect maximum light and sparkle. The cut is crucial as it directly affects the gem's brilliance and fire. A well-cut moissanite or lab diamond will exude unmatched brilliance, enhancing the overall beauty of the jewelry piece.


Carat refers to the gemstone's weight and size. In terms of carat weight, moissanite is generally lighter than diamonds of the same size. For example, a one-carat moissanite might look slightly smaller than a one-carat diamond. However, this doesn't necessarily mean it is less valuable as it often depends on personal preferences and budget.

Durability: Moissanite vs. Lab Diamonds

Both moissanite and lab diamonds are exceptionally durable, making them suitable for everyday wear. However, moissanite is slightly tougher than lab diamonds, which means it is more resistant to chipping and breaking. On the Mohs scale of hardness, moissanite scores a 9.25, while lab diamonds and natural diamonds both score a perfect 10.

Moissanite vs Lab Grown Diamond Price

One of the most significant advantages of choosing moissanite or lab diamonds is their affordability compared to natural diamonds. Moissanite is considerably less expensive than lab diamonds, making it an ideal option for those on a tighter budget. Lab diamonds, while more expensive than moissanite, are still significantly cheaper than natural diamonds, allowing you to get a larger and more dazzling stone for your money.

Environmental and Ethical Considerations


As moissanite is a naturally occurring gemstone, there are no ethical concerns related to its extraction. However, it's essential to ensure that the moissanite you purchase is lab-created or sourced from a reputable supplier to ensure ethical practices.

Lab Diamonds:

Lab-grown diamonds are highly regarded for their ethical and environmental benefits. Since they are created in controlled environments, there is no mining involved, eliminating the harmful impacts associated with diamond extraction. Choosing lab diamonds supports sustainable practices, making them a top choice for eco-conscious consumers.

Brilliance and Fire: The Sparkle Factor

Moissanite's higher refractive index gives it a unique sparkle, known as "fire," which is more pronounced than in lab diamonds. This mesmerizing play of light creates a dazzling display that can captivate anyone's attention. Lab diamonds, while still brilliantly sparkly, exhibit a more subdued fire compared to moissanite.

Moissanite or Lab Diamonds: The Personal Preference

Choosing between moissanite vs lab diamond ultimately comes down to personal preference and budget considerations. Some may prefer the icy white brilliance of moissanite, while others may opt for the versatility and color options of lab diamonds. Both gemstones have their unique charm and allure, making them equally appealing choices.

Maintenance and Care

Both moissanite and lab diamonds are easy to maintain and care for. Regular cleaning with mild soap and a soft brush can keep them looking their best. Additionally, it's essential to have your jewelry professionally inspected and cleaned periodically to ensure the stones are securely set and free from any damage.

Conclusion: A Gemstone That Shines Bright

In conclusion, whether you choose moissanite or lab diamonds, you'll have a stunning gemstone that shines brightly and symbolizes love and commitment. Moissanite offers an affordable and radiant option with exceptional fire, while lab diamonds combine beauty and ethics to create a truly dazzling choice.

Remember, when making your decision, consider your budget, personal style, and ethical values. Regardless of your choice, both moissanite vs lab diamond offer brilliant alternatives to natural diamonds, ensuring your jewelry piece will be cherished for a lifetime.
