The ruby's mineral name is corundum. (Note: In addition to ruby, other colors of sapphire are sapphire. For example, pink sapphire is called pink sapphire.) Only the red corundum colored by Cr can be called ruby. The pink corundum is not Cr-induced.
Ruby is a corundum mineral, trigonal. Because of its composition containing chromium and red to pink, the higher the content, the more vivid the color. Blood red rubies are the most treasured by people, commonly known as "pigeon blood red." Ruby and Emerald, Jinshui Bodhi Sapphire, tourmaline, etc. are all belong to colored gemstones. The texture of ruby is hard and the hardness is only under the diamond.
