About Moissanite

About Moissanite

A Celestial Sparkle with an Earthly Heart More than 50,000 years ago a meteorite collided with Earth in a fiery blaze and left behind trace crystals of a rare otherworldly mineral. These brilliant fragments were later discovered in an Arizona crater by French chemist Henri Moissan, who noticed they bore an uncanny resemblance to diamonds. It was not until eleven years later that Moissan identified the crystals as a unique compound known as silicon carbide. Today the gemstone born from the stars bears his name, Moissanite.
While natural moissanite is incredibly rare, modern science has perfected the art of recreating its cosmic brilliance ethically. Trésor proudly offers this enduring gem that rivals the sparkle of diamonds.

Trésor Moissanite vs. Cubic Zirconia

Feature Trésor Moissanite Cubic Zirconia
Brilliance Exceptional Fire & Sparkle Moderate Shine
Durability Highly Durable Prone to Scratches
Longevity Lasts a Lifetime Can Lose Brilliance Over Time

While cubic zirconia (CZ) has gained popularity as an affordable diamond substitute, it falls short in both appearance and longevity. What might seem like a budget-friendly option can quickly lose its sparkle literally.

The Difference You Can See and Feel

While cubic zirconia (CZ) has gained popularity as an affordable diamond substitute, it falls short in both appearance and longevity. What might seem like a budget-friendly option can quickly lose its sparkle literally.

Quality Starts at the Core

Cubic zirconia is often mass-produced using low-cost materials, which can result in visible imperfections, uneven color tones, and inconsistency across pieces. While both moissanite and CZ are created in labs, Trésor moissanite is crafted using cutting-edge technology to ensure every gem is perfectly colorless, flawless, and consistent in brilliance.

Durability That Endures

CZ is a much softer gemstone, scoring about 8.5 on the Mohs hardness scale. This means it’s more vulnerable to surface scratches, dulling, and absorbing oils or dirt over time. In contrast, Trésor moissanite boasts an impressive 9.5 hardness nearly as strong as a diamond. Your ring remains clear, radiant, and scratch-resistant for years to come.

Brilliance That Speaks for Itself

Because of its density and refractive qualities, moissanite naturally exhibits more fire and sparkle than CZ. Additionally, many mass market CZ stones are poorly cut, limiting their brilliance. Trésor moissanite is precision-cut to maximize light performance, creating exceptional scintillation that rivals and often exceeds natural diamonds.

A Better Investment in Beauty

Though CZ may seem economical upfront, its quality tends to fade. Trésor moissanite offers enduring elegance without compromise a gem that stays brilliant, stands strong, and still comes at a fraction of the cost of diamonds.

Color Matters And So Does Clarity
