Ruby is one of the highest valued colored gemstones, in fact, large rubies can fetch higher prices than equivalently sized diamonds. Ruby has been prized for centuries because of its excellent Mohs scale hardness of 9, along with its treasured rich red hue and vitreous luster. Ruby is a variety of corundum that gets its red color from chromium. Corundum that occurs in any color other than red, is classified as sapphire. In its pure form, corundum is completely colorless. The word "corundum" comes from the Tamil "kurundam", meaning "ruby sapphire"
Peridot is a gem-quality variety of the mineral olivine. It belongs to the forsterite-fayalite mineral series. Some even refer to peridot as 'olivine', but when it comes to the gemstone, 'peridot' is the correct term. Peridot is an idiochromatic gem, meaning its color comes from the basic chemical composition of the mineral itself and not from minor traces of impurities. Thus, peridot is found only in green. In fact, peridot is one of the few gemstones available that can be found only in one color, although the shades of green may vary from light yellowish to dark brownish-green.
