Moissanite vs. Diamond: A 2025 Buyer's Guide to Smart Luxury

Finding the perfect gemstone is a journey. For decades, the diamond has been the undisputed king of fine jewelry. But a brilliant, ethical, and more accessible contender has captured the hearts of modern jewelry lovers: Moissanite.

If you're wondering what the difference is—and which one is right for you—you've come to the right place. As a brand built on the beauty of this very gem, we want to give you an honest comparison.

Here’s the 2025 breakdown of Moissanite vs. Diamond.

What is a Diamond?

A diamond is a rare, naturally occurring mineral composed of pure carbon. Formed deep within the Earth over billions of years, its hardness and unique ability to reflect light have made it a powerful symbol of luxury, tradition, and everlasting love.

What is a Moissanite?

Moissanite is a stunningly brilliant gemstone composed of silicon carbide. It was first discovered in 1893 by a Nobel Prize-winning chemist, Henri Moissan, inside a meteorite crater in Arizona. He initially thought he had found diamonds, but soon realized he had discovered a new, "otherworldly" mineral.

Natural moissanite is rarer than diamond. The moissanite in jewelry today is meticulously created in a lab, allowing us to replicate its "stardust" origins in a stone that is ethical, sustainable, and visually breathtaking.

The Head-to-Head Comparison: Moissanite vs. Diamond

Let's break down the only factors that truly matter when choosing your forever stone.

1. Brilliance & Sparkle (The "Wow" Factor)

• Diamond: Has a renowned, fiery sparkle. It is singly refractive, meaning light enters, bounces, and exits in a single ray.

• Moissanite: This is where moissanite truly shines. It is doubly refractive, meaning light entering the stone is split into two rays, which bounce around more. This creates an exceptional, fiery, and colorful flash of "rainbow" sparkle that is even greater than a diamond's.

• Winner: Moissanite, for pure, unmatchable brilliance.

2. Durability & Hardness

• Diamond: The hardest known mineral on Earth, scoring a perfect 10/10 on the Mohs scale of hardness.

• Moissanite: At 9.25/10 on the Mohs scale, moissanite is the second-hardest gemstone on Earth, right behind the diamond. It is incredibly durable, resistant to scratches, and built for a lifetime of everyday wear—just like a diamond.

• Winner: A virtual tie. While a diamond is technically harder, moissanite is more than durable enough for any fine jewelry, including engagement rings.

3. Color & Clarity

• Diamond: Graded on a D-Z color scale. A "colorless" D-grade diamond is rare and extremely expensive. Most diamonds have a faint yellow or brown tint.

• Moissanite: Because it is created in a lab, high-quality moissanite (like the stones used by RELIK) is engineered to be perfectly colorless (D-F grade). It is also created with minimal inclusions, making it "eye-clean" or virtually flawless.

• Winner: Moissanite, for offering the perfection (colorless, high-clarity) that is almost unobtainable in a natural diamond without an astronomical price.

4. Price & Value (The "Smart Luxury" Choice)

• Diamond: The price of a diamond rises exponentially with its carat, cut, color, and clarity.

• Moissanite: A moissanite gemstone of the same size and quality as a diamond is up to 90% less expensive.

• Winner: Moissanite, by a landslide. This is the "smart luxury" choice. It allows you to get the stunning, 2-carat ring of your dreams for a fraction of the cost, without compromising on quality or beauty.

5. Sourcing & Ethics

• Diamond: The natural diamond industry has a long and complex history, often associated with environmental damage and "conflict diamonds."

• Moissanite: As a lab-created stone, moissanite is one of the most ethical and sustainable gems in the world. Its origin is 100% traceable, and it has no environmental or human rights concerns.

• Winner: Moissanite, for a 100% guilt-free and sustainable sparkle.

So, Which One Should You Choose?

The truth is, one is not "better" than the other—they are simply different.

• You should choose a Diamond if you deeply value tradition and the story of a natural gem created by the Earth.

• You should choose a Moissanite if you are a modern, conscious consumer who values exceptional sparkle, undeniable durability, and the "smart luxury" of getting a more brilliant, ethical, and perfect stone for a fraction of the price.

At RELIK, we built our brand on the "smart luxury" choice. We believe you shouldn't have to choose between quality, ethics, and price. With Moissanite, you get all three.
