The name tourmaline comes from a Singhalese word, « touramalli », meaning "mixed colored stones".
Tourmaline occurs in every color of the rainbow and also in combinations of two or three colors.
Sometimes the colors are at different ends of the crystal, while other times one color is in the heart of the crystal and another on the outside. When the later combination displays a pink center with a green rind it is called "watermelon tourmaline".
Pink /Red tourmalin is called Rubellite (rare and valuable), Vivid blue Tourmalin is called Paraiba (extremly rare and pricy).
The ability of this stone to look like other gemstones led to some confusions.
Many gemstones in the Russian Crown jewels from the 17th Century once thought to be rubies are in fact tourmalines.
Mainly mined in United States, Russia and Brazil
