In terms of colour, tourmalines are the
cornucopia of mother nature's colour spectrum. No other
gemstone offers more variety of colour than the tourmaline.
The origin of "tourmaline" is subject of argument, however, it has
been suggested that it originated from the Sinhalese turnali,
a name applied by local jewellers to yellow zircon.
Tourmaline has been found in significant
quantities in Brazil, California, Pakistan, Afghanistan, Africa,
Madagascar and Sri Lanka. Recently there has been an
interesting find in Mozambique of green and purple tourmaline,
although because of the inclusion properties it is also being called
rubellite, a term ordinarily reserved for red tourmaline.
