Choosing the perfect gemstone for your jewelry can feel like a dazzling challenge. Whether you’re shopping for an engagement ring, anniversary gift, or simply something stunning for yourself, you’ve likely come across the terms moissanite diamond and man made diamonds. While both offer ethical and affordable alternatives to natural diamonds, they differ in more ways than one. In this article, we’ll compare these two sparkling options in depth, helping you understand their origins, appearance, price, durability, and more.
What is a Moissanite Diamond?
A moissanite diamond is a gemstone originally discovered by French scientist Henri Moissan in 1893. Found in a meteor crater, this naturally occurring mineral is composed of silicon carbide. However, natural moissanite is extremely rare, so the stones sold today are lab-created.
Despite its name, a moissanite diamond is not a real diamond. It is a diamond simulant, meaning it looks similar but has a different chemical composition. Its fire and brilliance often surpass those of a natural diamond, making it a popular alternative for people who want that extra sparkle without the hefty price tag.
What Are Man Made Diamonds?
Man made diamonds, also known as lab grown or synthetic diamonds, are chemically, physically, and optically identical to natural diamonds. They are created in laboratories using advanced technologies that replicate the high-pressure, high-temperature conditions under which diamonds form in the earth.
Unlike simulants like moissanite, man made diamonds are real diamonds. They are graded using the same 4Cs (Cut, Color, Clarity, Carat) as mined diamonds and can even be certified by reputable gemological labs like GIA or IGI.
Appearance: Sparkle and Shine
When it comes to brilliance, both a moissanite diamond and man made diamonds shine beautifully — but differently.
-
Moissanite has a higher refractive index (2.65) than a diamond (2.42), which means it reflects more light and creates a “disco ball” effect. Some people love this sparkle, while others find it too flashy.
-
Man made diamonds, being real diamonds, have the same subtle sparkle and scintillation as mined diamonds. They reflect white and colored light in a balanced, classic way.
So, if you want over-the-top brilliance, a moissanite diamond might be your pick. But for traditional elegance, man made diamonds may be the better choice.
Price Comparison
One of the most noticeable differences between a moissanite diamond and man made diamonds is the price.
-
A moissanite diamond can cost up to 90% less than a mined diamond of similar size.
-
Man made diamonds are typically 30-50% less expensive than natural diamonds, but still cost more than moissanite.
This significant price difference is why many budget-conscious buyers lean toward moissanite. You can get a larger stone for the same budget. However, those looking for long-term value and authenticity might prefer man made diamonds despite the higher price tag.
Durability and Daily Wear
Durability is crucial, especially for rings worn daily.
-
A moissanite diamond scores 9.25 on the Mohs hardness scale. It’s extremely durable and suitable for everyday wear, though slightly less hard than diamonds.
-
Man made diamonds score a perfect 10, just like mined diamonds. They are the hardest known material on Earth and can resist scratches better than any other gemstone.
If you’re tough on your jewelry or want a family heirloom, man made diamonds offer the ultimate durability. But for everyday beauty at a fraction of the cost, a moissanite diamond still holds up remarkably well.
Ethical and Environmental Considerations
Both options are far more ethical than traditional diamond mining, which has been linked to environmental damage and human rights concerns.
-
A moissanite diamond is entirely lab-created and doesn’t require mining, making it a 100% conflict-free option.
-
Man made diamonds are also eco-friendly and conflict-free, though the energy used in their production can vary based on the lab’s practices.
Overall, choosing either a moissanite diamond or man made diamonds supports sustainable jewelry practices and avoids the issues tied to “blood diamonds.”
Certification and Value Retention
One area where man made diamonds shine brighter is in certification and resale value.
-
Man made diamonds can be certified by the same gemological labs that certify mined diamonds. This provides assurance about quality and can help with resale.
-
A moissanite diamond, while beautiful, is not typically certified using the same grading systems. Its resale value is also lower, as it’s considered a simulant rather than a precious gem.
So, while a moissanite diamond is perfect for those who prioritize looks over long-term value, man made diamonds may offer more in terms of appraisal and investment.
Popularity and Market Trends
The demand for both moissanite diamond and man made diamonds has surged in recent years, especially among Millennials and Gen Z buyers. These generations value transparency, sustainability, and affordability — all qualities these stones embody.
Jewelry designers are now offering full collections with both stones, from minimalist solitaires to elaborate halo settings. And with celebrities like Meghan Markle and Emma Watson embracing sustainable gems, these trends are only expected to grow.
Which One Should You Choose?
Ultimately, the choice between a moissanite diamond and man made diamonds comes down to your preferences and priorities:
| Factor | Moissanite Diamond | Man Made Diamonds |
|---|---|---|
| Brilliance | More Fire & Sparkle | Classic Diamond Sparkle |
| Durability | 9.25 Mohs | 10 Mohs (Very Hard) |
| Price | More Affordable | Higher, but Less than Mined |
| Real Diamond? | No (Simulant) | Yes |
| Certification Available? | Limited | Yes (GIA, IGI, etc.) |
| Ethical & Sustainable | Yes | Yes |
| Resale Value | Lower | Higher |
If you’re after beauty on a budget and love extra sparkle, go with a moissanite diamond. If you want an authentic, certified gem with timeless value, man made diamonds are the better choice.
Conclusion
Whether you’re drawn to the fiery brilliance of a moissanite diamond or the authentic elegance of man made diamonds, one thing is clear: you don’t have to sacrifice ethics or beauty when buying jewelry today. Both options deliver serious sparkle, environmental responsibility, and affordability.
Jewelry is a personal expression, and there’s no one-size-fits-all answer. By understanding the unique traits of each stone, you can confidently choose the one that matches your style, values, and budget — and shine with pride every time you wear it.
