Composition Sapphire is a kind of precious gemstone, a variation of the mineral corundum that forms in prismatic rhombohedral crystals. Blue is the “true” color of sapphires as it is the most known color, but sapphire often comes in yellow, purple, orange, and green shades. Madagascar is the world leader in sapphire processing, particularly from its mines around the city of Ilakaka while sapphires from Kashmir, Burma, or Sri Lanka are the most coveted.
