When you think of black tourmaline you might consider high quality terminated single and multiple crystal formations to polished
tumblestones, but have you considered more commercial applications?
Powdered tourmaline as an ingredient to ceramic water/air purifyers, showers, swimming pools and fridges.
Tourmaline comprises of several different elements including aluminium, boron, iron, lithium, magnesium and manganese. It has
interesting electrical properties, similiar to quartz it exhibits piezoelectric properties(when physically stressed) and it also has pyroelectric properties(can create a voltage through temperature change).
In 314 BC tourmalines intriguing features were noticed with further documentation in the mid 1800’s and tourmaline nicknamed Lapidem Electricum(electric stone) and finally in the 1900’s it’s qualities were formally named.
Most industrial uses of tourmaline relate to it’s pyroelectric features which include emission of far infrared radiation, release of negative ions, absorption of ions, biologic activity influence. Oh it also helps with protecting against negativity,
relieving stress and cleansing you from negative energy. So next time don’t overlook this rather humble black crystal.
