Moissanite, also known as silicon carbide, is a rare, naturally occurring mineral discovered by French chemist Henri Moissan in 1893. It was later synthesized in a lab and has become popular as an alternative to diamonds in jewelry, an affordable and ethical choice in the market.

Brilliance refers to the amount of light that enters a gemstone and is reflected back to the observer's eye. Moissanite has a refractive index of 2.65, while diamond's is 2.42. Given their similar refractive properties, both gems can exhibit remarkable brilliance.

Fire is a measure of a gemstone's ability to separate white light into spectral colors, resulting in a dazzling, rainbow-like effect. Moissanite exhibits a higher dispersion rate at 0.104, compared to natural diamond's rate of 0.044. Consequently, moissanite tends to display more fire, often causing a noticeable rainbow effect.

for Durability, while diamonds are renowned for their hardness, scoring a perfect 10 on the Mohs scale; Moissanite, is an impressive 9.25. This makes them highly resistant to scratches and damage, ideal for a jewelry that's worn daily.
