Introduction to Sapphire [Introduction to Sapphire Course 1]

Like rubies, sapphires belong to the corundum (Al2O3) mineral group; the name sapphire covers corundum of all colors except red (i.e., ruby). Although sapphires are sometimes considered just "blue sapphires," in fact this type of gemstone has a series of fascinating colors. Sapphires of other colors except blue are usually called colored sapphires. Among them, pink, green, lotus sapphires (pink orange to orange pink), orange, purple, black, gray, brown, and many intermediate colors.

The island country of Sri Lanka has been an important source of sapphires since ancient times. In Myanmar, although Mogok is a well-known ruby producing area, it has been steadily producing high-quality sapphires for centuries. The most famous sapphire producing area in Kashmir, although it has a long history, is no longer active. In addition, Madagascar is the most active high-quality sapphire producing area since the 1990s.
