Are Moissanites Better Than Diamonds? 2025
As someone who’s spent years studying, comparing, and writing about fine jewelry, I’ve often been asked the same burning question: are moissanites better than diamonds? The answer isn’t simple—but it is fascinating. When it comes to engagement rings, wholesale jewelry, and ethical alternatives, moissanite has quickly risen to fame as a stone that rivals, and in some ways even surpasses, natural diamonds. Moissanite is not a synthetic diamond—it’s a unique gemstone with its own extraordinary properties. First discovered in a meteor crater in 1893, moissanite is nearly as hard as diamonds, shines brighter, and costs a fraction of the price.
For those shopping smart—whether brides-to-be, jewelry retailers, or wholesale buyers—understanding the differences between moissanite vs diamond can make all the difference in selecting the perfect stone. Today, consumers are more conscious than ever about sustainability, value, and ethical sourcing. That’s where moissanite shines: it offers unparalleled brilliance without the environmental footprint or ethical concerns often tied to mined diamonds.
In this guide, I’ll break down the facts—hardness, brilliance, cost, durability, ethics, and resale value—so you can make an informed choice. Let’s dive deep into the science, sparkle, and symbolism behind both gemstones, and see why moissanite is taking the jewelry world by storm.

What Is Moissanite?
Moissanite is a lab-grown gemstone made from silicon carbide. Unlike cubic zirconia, which is a diamond simulant, moissanite is considered a diamond alternative because of its hardness and fire. It was first discovered in microscopic crystals inside a meteorite crater, making it literally “born from the stars.” Today, scientists recreate moissanite in laboratories, ensuring consistent quality, ethical production, and affordability.
Hardness & Durability: Moissanite vs. Diamond
When choosing an engagement ring or fine jewelry, durability is crucial. Diamonds rate a 10 on the Mohs scale of hardness, making them the hardest known natural material. Moissanite ranks at 9.25–9.5, which means it’s nearly as durable and scratch-resistant.
For daily wear—especially in engagement rings—this hardness ensures that moissanite will last for generations. Unlike softer gemstones such as sapphires, emeralds, or cubic zirconia, moissanite doesn’t cloud or wear easily. In fact, jewelers often recommend moissanite as the best diamond substitute for couples who want long-lasting sparkle without compromise.

Brilliance & Fire: Which Sparkles More?
If you’ve ever noticed a moissanite ring under bright light, you’ll know why so many people fall in love instantly. Moissanite actually has a higher refractive index (2.65–2.69) compared to diamonds (2.42). That means moissanite bends light more dramatically, resulting in greater brilliance and fire—the colorful rainbow flashes that jewelry enthusiasts adore.
Some purists argue that moissanite’s sparkle is “too much,” but for many buyers, this is a selling point. Under candlelight or natural sunlight, moissanite often looks even more dazzling than a diamond.
Price & Value: The Smart Buyer’s Choice
Perhaps the biggest difference between moissanite and diamonds lies in price. A one-carat natural diamond can cost anywhere from $4,000–$10,000, depending on cut, clarity, and color. In contrast, a comparable moissanite stone typically costs just a few hundred dollars.
For couples seeking luxury without financial strain—or retailers stocking wholesale jewelry—this price gap is game-changing. Moissanite allows you to purchase larger, higher-quality stones at a fraction of the diamond cost. Importantly, this doesn’t mean moissanite is “cheap”—it’s an affordable luxury with enduring beauty.

Ethical & Environmental Considerations
Diamonds, particularly those mined in conflict zones, have long raised ethical concerns. Even with the Kimberley Process, diamond sourcing can still involve questionable labor practices and significant environmental impact. Moissanite, on the other hand, is lab-created, meaning it is conflict-free, eco-friendly, and sustainable.
For eco-conscious couples and socially responsible jewelers, choosing moissanite is a powerful statement. It allows you to wear a stunning gemstone with confidence, knowing it wasn’t sourced at the expense of human rights or the environment.
Resale Value & Investment
One area where diamonds traditionally hold an edge is resale value. Natural diamonds can sometimes retain or appreciate in value, particularly rare cuts or high-quality stones. Moissanite, being lab-grown, doesn’t carry the same long-term investment potential.
That said, most jewelry buyers purchase engagement rings or fine jewelry for emotional value, not resale. In practice, very few consumers ever sell their rings. When the focus is on beauty, durability, and everyday brilliance, moissanite delivers unmatched value.
