Ruby is one of the traditional cardinal gems, together with amethyst, sapphire, emerald, and diamond. The word ruby comes from ruber, Latin for red. The color of a ruby is due to the element chromium.
It is favorite gem among those in power and those in love, inspiring more emotion than almost any other stone. Some ancient cultures believed that rubies, as well as other gemstones, grew on trees, just like fruit. The rubies would begin budding as small white gems, and would slowly grow and ripen, turning red in the light of the sun. When the ruby was saturated with red color, it was ready to be plucked.
