Blue is the best-known of the sapphire colors. The prized Kashmir and Burmese sapphires have a deep blue that is intense and velvety. These sapphires are not often seen on the market today. Sri Lankan and Madagascar sapphires are the most common today, with a wide range of colors from light blue to dark blue. Sapphire is a gem quality variety of corundum. It is closely related to ruby, which is corundum distinguished only by its red color. Sapphire of any other color is often referred to by a color-specific name; i.e., yellow sapphire, green sapphire or violet sapphire. Colorless sapphire is sometimes known as leuko-sapphire, and rare pinkish-orange sapphire is known as ‘padparadscha’, a Sinhalese word for ‘lotus flower’. The name Sapphire derives from Greek “sappheiros” – blue. In antiquity, any blue stone such as lazurite, was called Sapphire. Sapphires are commonly worn in jewelry.
