In the 3rd century BC, we found traces of this stone. In Greece, it was Alexander the Great (356-323 BC) who brought this stone back from these expeditions. However, tourmaline, due to its many colors, has very often been confused with other minerals.\u003c\/span\u003e\u003cbr style=\"font-family: \" playfair display georgia serif font-size:\u003e \u003cspan style=\"font-family: \" playfair display georgia serif font-size:\u003eThus, there are very few legends or myths attached to this stone due to its late identification. However, some tourmalines have piezoelectric properties, meaning they have an electric charge, negative at one pole and positive at the other pole.
