Moissanite vs. Diamond: A Brilliant Alternative
The engagement ring industry spent decades convincing people that only a diamond would do. That story is changing — and moissanite is a large reason why.
Silicon carbide crystals were first discovered in a meteor crater in 1893 by French chemist Henri Moissan. Natural moissanite is extraordinarily rare. Today it's grown in labs to gem quality, and the result is a stone that rivals — and in some ways surpasses — diamond.
Here's the honest comparison.
Hardness and durability
Diamond is the hardest natural material on earth, rating 10 on the Mohs scale. Moissanite comes in at 9.25 — harder than sapphire, harder than ruby, and hard enough that daily wear won't scratch or damage it under any normal circumstances.
For an engagement ring or any piece meant to last a lifetime, moissanite is durable enough. The difference between 9.25 and 10 is not something you'll feel in everyday life.
Brilliance and fire
This is where moissanite surprises people. Moissanite has a higher refractive index than diamond (2.65–2.69 vs. 2.42), which means it bends light more, producing more brilliance and more fire — those rainbow flashes of color that catch the light.
Some people love this. Some prefer the more subdued sparkle of a diamond. Neither is wrong; it's a matter of preference. If you want maximum visual impact, moissanite delivers it.
Ethics and origin
This matters to a growing number of buyers. The diamond industry has made progress on conflict stone sourcing, but questions about labor conditions and environmental impact remain complex and often opaque.
Moissanite grown in a lab has a clear supply chain. You know exactly where it came from. For buyers who want that certainty, lab-grown moissanite is the cleanest answer.
Price
A one-carat diamond of VS1 clarity and G color typically costs between $4,000 and $6,000 CAD. An equivalent moissanite — same size, comparable brilliance — costs a few hundred dollars.
That difference is significant. It means a larger stone for the same budget, or budget redirected toward a more elaborate setting, a honeymoon, a house — whatever matters more.
Who moissanite is right for
- Buyers who want a large, brilliant center stone without a large center-stone budget
- Anyone who values supply chain transparency and wants a clean ethical story
- People who prefer the higher fire and rainbow flash that moissanite produces
- Those who understand that the meaning in a ring comes from the relationship, not the material
Who might still choose diamond
- Those for whom diamond holds specific cultural or sentimental significance
- Buyers who want the prestige and resale value that diamond carries
- Anyone who prefers the slightly warmer, more subdued sparkle that diamond produces
