Complement her bold and beautiful personality with the breathtaking color, dramatic design and unending sparkle of this spectacular gemstone. From deep reds to pastel pinks, from dark greens to vivid yellows and vibrant blues, Tourmaline crystals have the widest range of colors of all gemstones. It is not surprising that throughout their history, Tourmalines have been identified as everything from rubies to sapphires to emeralds.Modern scientists have identified Tourmaline as a large group of boron silicate minerals which owe their variety of colors to the presence of additional minerals such as iron, manganese, titanium and copper. Even naturally occurring radiation has been known to cause color variation in these beautiful stones. Tourmalines can be found on all of the world's continents but are mined predominantly in Brazil and many parts of Africa. South Asia also has some fine deposits (the name tourmaline has its origins in Sinhalese, the ancient language of Sri Lanka) and North America has produced some world class examples. Tourmalines have been described as a semi-precious stone despite the fact that certain varieties are much rarer than diamonds and can be considerably more expensive.
Tourmalines are unique in their variety of colors, the entire rainbow is covered and unusually, two or even three color specimens can be found.
