Tourmaline

Tourmaline, a beautiful gemstone with mysterious properties that have intrigued early philosophers since the time of Ancient Greece. Not only it has the broadest colour spectrum among crystalline gems but it also shows two interesting properties, piezoelectricity and pyroelectricity. Its structure can accommodate different atoms and as a result, there are many multi colour crystals. Tourmaline gemstones were not recognised as a species until 18th century. The red and green varieties were commonly mistaken with ruby and emerald before modern tests were introduced. Late Chinese Empress Cixi was especially fond of Rubellite Tourmaline gemstones and purcharsed a great amount of them from Californian mines. Today we have great variety of colours mined across the globe and Tourmaline gemstone can sell form a couple Dollars a carat for common variety, low quality stones to tens of thousands per carat for good quality, rare varieties like Paraiba.
