Tourmaline is the birthstone of October and is a favourite gemstone amongst jewellery designers, and gem collectors around the world. Since it is available in a wide variety of colours, it is ideally suited to almost anyone's taste. The word tourmaline is believed to have been derived from the Singhalese word 'Toramalli1 , meaning 'something out of the Earth'. Interestingly, Benjamin Franklin used tourmaline in his studies of electricity. Tourmaline is found in many localities including Brazil, Afghanistan, East Africa, and the Unites States.
