The Stone

Why Moissanite

A Gemstone Unlike Any Other

Moissanite is one of the world’s most remarkable gemstones, celebrated for its extraordinary brilliance, exceptional durability, and timeless beauty.

With a 9.25 rating on the Mohs hardness scale, second only to diamond, moissanite is highly resistant to scratching and designed for a lifetime of everyday wear.

One of its most distinctive qualities is its incredible sparkle. Thanks to its higher refractive index and greater light dispersion (fire), moissanite often displays even more brilliance and colorful flashes than a diamond under many lighting conditions.

Every Piragine & Co. moissanite is precision-cut to maximize its beauty, delivering exceptional clarity, brilliance, and symmetry. The result is a gemstone that captures light from every angle and shines with remarkable intensity.

Moissanite is also an ethical and sustainable choice, offering the luxury and beauty of a premium gemstone without the environmental impact associated with traditional mining.

Because of its high thermal conductivity, moissanite can register as a diamond on many standard diamond testers. While advanced gemological equipment can distinguish the two gemstones, moissanite has earned its own reputation as one of the finest gemstones available today.

At Piragine & Co., we believe true luxury is defined by exceptional beauty, outstanding craftsmanship, and lasting value.

The Celeste ring is more brilliant in person than I could have imagined. The family wrote a handwritten note. It felt like couture.
