Moissanite vs. Diamond: The Myths and Shining a Light on the Truth

Diamonds have been the most popular gemstone for ages and are chosen for engagement rings, symbolizing love, commitment, and enduring brilliance. According to, approximately US$72 of diamond jewelry is sold annually. 

But in recent years, a dazzling challenger has emerged– Moissanite. It is a lab-grown gemstone that boasts incredible sparkle, ethical sourcing, and affordability, which makes it a compelling alternative for the modern couple.

However, with the increase in popularity, you will find several myths and misconceptions surrounding Moissanite, leaving much confusion about its true qualities compared to Diamonds. 

Moissanite vs. Diamond


Diamonds: A Legacy of Tradition and Sparkle

Diamonds have held a coveted position in jewelry for ages due to their inherent beauty and scarcity. Their exceptional hardness and fire produce a captivating brilliance that never fails to enthrall. 

The tradition further cements the association of diamond engagement rings with love and devotion, which is ingrained in cultural standards and marketing strategies.

However, diamonds come with their own set of considerations. Their mining can be associated with ethical concerns, environmental impact, and potential human rights abuses. Additionally, their high price tag can often significantly strain couples' budgets.

Moissanite: A Sparkling Gemstone

Later in the 19th century, Moissanite was discovered. This iced out jewelry is a lab-grown gemstone with remarkable similarities to diamonds. Its brilliance sometimes rivals, and even surpasses, diamonds due to its higher refractive index.

Moissanite exhibits exceptional fire, creating a breathtaking rainbow sparkle that can be even more captivating than diamonds under certain lighting conditions.

But the true advantages of moissanite lie beyond its brilliance. Unlike diamonds, Moissanite is created in controlled lab environments, ensuring ethical sourcing and minimal environmental impact.

Myths About Diamond Vs. Moissanite

1. Moissanite is Less Durable Than Diamonds

There is a common misconception that moissanites are not as durable as diamonds. As it happens, Moissanite is a strong gemstone, ranking second on the Mohs hardness scale only to diamonds. This indicates that, like diamonds, Moissanite is scratch-resistant and suitable for everyday use.

But the truth is Moissanite is composed of silicon carbide and possesses a Mohs hardness rating of 9.25, making it highly durable for everyday use. While diamonds remain the hardest mineral with a perfect 10 rating, the difference in hardness between Moissanite and diamonds is minimal in practical terms.

2. Diamonds are Significantly More Brilliant

Another common misconception revolves around brilliance, with some believing that diamonds outshine Moissanite in sparkle and luminosity. However, this myth obscures that Moissanite exhibits exceptional brilliance and fire, often surpassing diamonds in certain lighting conditions.

However, Moissanite's high refractive index contributes to its remarkable brilliance, displaying flashes of color and sparkle that captivate the eye. In ideal lighting, Moissanite can even outshine diamonds, creating a breathtaking display of fire that adds a unique allure to the gem.

3. Moissanite Lacks Value Compared To Diamonds

A prevailing misconception suggests that choosing Moissanite is a compromise on value. However, the reality is that Moissanite offers a more affordable alternative without sacrificing beauty or quality.

Moissanite's affordability doesn't equate to inferiority; it allows couples to invest in a stunning gem without breaking the bank. With a lower price point, individuals can distribute resources to other aspects of their lives while still enjoying the elegance and charm of a moissanite engagement ring.

4. Moissanite is Less Ethical and Environmentally Friendly

Some may erroneously believe that diamonds are a more ethical and environmentally friendly choice due to the prevalence of conflict-free and responsibly sourced options.

Contrarily, Moissanite can offer a more ethical alternative without compromising on beauty. Moissanite is typically created in a lab, minimizing the environmental impact related to traditional diamond mining. Additionally, the moissanite industry is committed to ethical practices, providing consumers with conflict-free and responsibly sourced options.

5. Diamonds are the Only Timeless Choice

The myth that diamonds are the only timeless and classic choice for engagement rings disregards the unique characteristics that make Moissanite an equally compelling option. Moissanite's distinct qualities offer a chance for couples to embrace individuality.

Moissanite's brilliance, fire, and affordability allow couples to create a unique and personal symbol of their love. With various cuts, shapes, and customization options, moissanite engagement rings can be tailored to the couple's style and preferences.

How to Choose the Right Gemstone?

Choosing between a diamond and a moissanite engagement ring ultimately boils down to personal preferences and priorities. Consider the following factors:

  • Budget- Be honest about your financial comfort level. Diamonds, while classic, carry a hefty price tag. Explore more affordable alternatives like Moissanite, white sapphires, or lab-grown diamonds, which offer similar brilliance at a fraction of the cost. Remember, the true value lies in the sentiment, not the price tag.
  • Ethical Considerations- Do you yearn for a stone mined responsibly and sustainably? Consider lab-grown gems like Moissanite or gemstones sourced through ethical programs. Research the gemstone's origin and mining practices to align your choice with your values.
  • Personal Style- Are you drawn to timeless elegance or bold statement pieces? Do you prefer vibrant colors or subtle hues? Reflect on your personality and wardrobe aesthetic. Gems like emeralds, rubies, and sapphires add pops of color, while opals and pearls offer soft sophistication. Choose a stone that reflects your unique style and resonates with your spirit.
  • Transparency- Don't be shy about asking questions! A reputable jeweler should be transparent about the stone's origin, treatment history, and grading certificates. Understand the terminology, and don't hesitate to seek clarification on any doubts. Remember, an informed decision is an empowered decision.


Remember, there is no "right" or "wrong" answer. Both diamonds and Moissanite are beautiful gemstones with unique qualities. By understanding the facts and aligning your choice with your values and budget, you can select the perfect gemstone that symbolizes your love and shines brightly for years to come.
