What Is Moissanite?

Moissanite is a rare gemstone first identified in 1893 by Nobel Prize–winning chemist Dr. Henri Moissan while examining a meteor crater. Naturally occurring moissanite is exceptionally scarce, which is why today it is responsibly recreated using advanced laboratory techniques.

The result is a gemstone known for remarkable brilliance, durability, and consistency—engineered to perform at the highest standard.

Caring for Your Moissanite

Clean with warm water, mild soap, and a soft brush

Avoid harsh chemicals and extreme temperature changes

Store in a padded box or soft pouch when not in use

Not All Sparkle Is Created Equal

Cubic Zirconia Imitates.
Diamonds Demand Compromise.
Moissanite Redefines the Standard.

Engineered for brilliance, moissanite delivers superior fire, exceptional durability, and diamond-tested performance—without the ethical, environmental, or financial excess of traditional stones. Its optical precision produces a sharper, more consistent sparkle that doesn’t fade with time or trends.

At Northstone, we don’t chase tradition. We refine it.
Moissanite isn’t an alternative—it’s the evolution of fine jewelry.

  • Moissanite Hardness

    Moissanite measures 9.25 on the Mohs Hardness Scale, just below diamond at 10. This level of hardness gives it exceptional resistance to scratches and surface wear, making it well-suited for daily use while maintaining its clarity and finish over time.

  • Moissanite Fire

    Moissanite is known for its pronounced fire, producing crisp flashes of spectral light that are especially visible in natural sunlight. This heightened dispersion gives each piece a lively brilliance, adding depth and movement without overwhelming the design.

  • Moissanite Brilliance

    While diamonds are known for a balance of brilliance, dispersion, and scintillation, moissanite offers a distinct optical profile of its own. With a refractive index of 2.65–2.69, higher than that of diamond, moissanite returns light with heightened intensity and clarity.
