Collection: Corundum Rough
Flame fusion corundum, also known as synthetic sapphire, is a lab-created gemstone produced through a process involving the melting of aluminum oxide powder in a flame. This method mimics the natural formation of sapphire crystals but accelerates the growth under controlled conditions. The resulting gemstone is durable, transparent, and often used in various industrial applications and as a substitute for natural sapphires in jewelry.
