Moissanite is a gemstone that closely resembles a diamond but is made from silicon carbide. Discovered in 1893 by Henri Moissan, it was originally found in a meteorite. Today, most moissanite is lab-created, making it an ethical and affordable alternative to natural diamonds. Moissanite is known for its brilliance and fire, often exhibiting more sparkle than diamonds due to its higher refractive index. It is durable, scoring 9.25 on the Mohs scale of hardness, which makes it suitable for everyday wear in jewelry, such as engagement rings and earrings.
