Ruby is a precious gemstone that belongs to the corundum mineral species. It is a red variety of corundum, and its red color is caused by the presence of chromium in the crystal structure. Ruby is one of the traditional cardinal gemstones, along with sapphire, emerald, and diamond. Ruby is typically a deep, rich red color, but it can also range from pinkish-red to purplish-red. Ruby can be transparent or opaque. Stones that are more transparent and have fewer inclusions are considered more valuable.
