Moissanite 4.0 carat Moissanite ring, size 6.

High-quality 4.0 carat Moissanite ring, size 6. Moissanite is a brilliant, highly durable, and eco-friendly gemstone composed of silicon carbide, often used as a popular ethical alternative to diamond. Originally found in meteorites, nearly all jewelry-grade moissanite is now lab-created. It is nearly as hard as diamond (9.25-9.5 on the Mohs scale) and boasts a higher refractive index, producing more fire and sparkle. It provides a similar, yet more affordable, look compared to mined diamonds. Cleaning and Care Moissanite does not get cloudy or lose its brilliance over time. It can be cleaned using warm water, mild soap, and a soft brush, or with standard ultrasonic jewelry cleaners.
