Other sought after varients are indoclite and rubellite. This gem is often confused with many others due to the number of colors it comes in. It has a mohls hardness of 7-7.5 and a refractive index of 1.614-1.666. If you were born in October.the gem trade's recognized birthstone for October but in 1952 the Jewelry Industry Council suggested that pink tourmaline be an alternate stone to opal. Brazil has produced many fine tourmaline crystals of many colors that have found use both as cut gems and as museum specimens. The Black Hills of South Dakota have produced some finely colored blue gemstones that have been rarely used for gems because of small size. Always buy from a reliable gemstone dealers.
