Moissanite is a gemstone that is made of silicon carbide, a synthetic material that is created in a laboratory. It is known for its hardness, durability, and fire, and is often used as an alternative to diamonds in jewelry.

Moissanite is typically colorless, but it can also be found in shades of yellow, green, and pink. It is an affordable alternative to diamonds, and is often used in engagement rings, wedding bands, and other types of fine jewelry.
