Cool Facts:
Black tourmaline (schorl) is pyroelectric: heat it and it develops an electric charge at each end, which is how it got the name "ash-puller" from Dutch traders.
Tourmaline's name comes from the Sinhalese turmali, "mixed-coloured stones".
It grows as long striated prisms, and the striations run the length of the crystal.
