‌Blue Sapphire
‌Blue Sapphire

 

The name Sapphire (Greek-Blue) used to be applied to various stones. In antiquity and as late as the Middle Ages, the name sapphire was understood to mean what is today described as lapis lazuli. Around 1800 it was recognized that sapphire and ruby are gem varieties of corundum. At first only the blue variety was called sapphire, and corundums of other colors (with the exception of red) were given special, misleading names, such as "Oriental Peridot" for the green variety or "Oriental Topaz" for the yellow type.
