Crystal Clarity: 

The secret to moissanite’s brilliance lies deep within its crystal structure. Moissanite is composed of silicon carbide (SiC) arranged in a hexagonal lattice. This unique structure allows moissanite to disperse light differently than other gemstones. When light enters, it bounces around within the crystal, creating what’s known as “fire.” This dispersion of light into a spectrum of colors is the primary reason moissanite’s sparkle is so enchanting and vibrant.

Refractive Marvel: 

The refractive index (RI) is another key element contributing to moissanite’s brilliance. Moissanite boasts a remarkable RI of 2.65-2.69, significantly higher than that of most gemstones, including diamonds (RI of approximately 2.42). A higher RI means that moissanite bends and refracts light to a greater degree, resulting in a more stunning play of colors and a remarkable display of sparkle.

Dispersion Delight: 

Moissanite’s dispersion, also known as “fire,” is one of its most distinctive characteristics. This property measures the extent to which white light is broken down into its individual spectral colors. Moissanite’s dispersion rating of 0.104 is nearly double that of diamonds, which have a dispersion rating of 0.044. The greater the dispersion, the more colorful the fire, and moissanite excels in this department, casting a captivating, rainbow-like display of colors in the right lighting.

Tough as a Gem:

While brilliance is undoubtedly important, durability is equally essential in the world of gemstones. Moissanite doesn’t disappoint here either. It ranks at 9.25 on the Mohs scale of mineral hardness, making it an incredibly durable choice for jewelry. In fact, it’s second only to diamonds, which score a perfect 10. This high level of hardness ensures that your moissanite gemstone will remain beautiful and unblemished even after years of wear.

Sustainability and Ethical Choice: 

Beyond its captivating brilliance, moissanite is also an ethical and sustainable choice. Unlike mined diamonds, the production of moissanite doesn’t involve environmentally damaging mining operations or ethical concerns. It’s lab-grown with minimal environmental impact and without any association with conflict regions. Moissanite allows you to adorn yourself with a stunning gem while preserving the planet’s natural resources and promoting ethical practices.
