| Tourmaline with its
mixture of colors takes its name from the ancient work “turmali” which
means “mixed precious stones”. In the
17th century tourmaline was mistakenly called “Brazilian
emeralds” due to the long prisms of dark green rough
being exported from Brazil. In the 18th century
it was discovered that these “Brazilian emeralds” were
not true emeralds but actually a gem possessing and unusual
property not known to emeralds. They can attract
or repel light-weight substances such as ashes. Tourmaline
comes in a wide variety of brilliant colors. Some
tourmaline comes in bi-colors (more than one color in
the same stone) |
