The amazing world of Tourmaline.
Most people consider tourmaline to be a single mineral. But in fact it is a group named for several different, but closely related minerals. Members of the Tourmaline Group are favourites among mineral collectors. Their rich and varied colours can captivate the eye. Even the black opaque tourmalines can shine nicely and produce sharp crystal forms. Tourmalines are cut as precious gems, carved into figurines, cut as cabochons, sliced into cross-sections and natural specimens are enthusiastically added to many crystal collections.
There are many unique properties of tourmalines.
First, they are piezoelectric which means that when a crystal is heated or compressed (or vibrated) a different electrical charge will form at opposite ends of the crystal (an electrical potential). Conversely if an electrical potential is applied to the crystal, it will vibrate.
Secondly they are pleochroic which means that the crystal will look darker in colour when viewed down the long axis of the crystal than when viewed from the side. This property goes beyond the idea that the crystal is just thicker in that direction. Even equally dimensioned crystals will demonstrate this trait.
The four most common and well known tourmalines are distinguished by their colour and transparencies.
Elbaite is the tourmaline that most people know and comes in many varied and beautiful colours. It is transparent to translucent and is highly prized as mineral specimens and as gemstones. Elbaite is easily the most colourful of all the gemstones.
The iron rich schorl is black and opaque. It is a common accessory mineral in igneous and metamorphic rocks and can form nice crystals. When found as inclusions in quartz, this stone is called "tourmalinated quartz".
Usually when someone refers to tourmaline they are referring to either elbaite or schorl.
The two other tourmalines; dravite and uvite are much less common than elbaite or schorl, but they are getting noticed for their beautiful specimens. Some of dravite's crystals are nicely formed, translucent brown and they can reach a rather large size. Uvite is a green translucent to opaque tourmaline that is growing in popularity and is being cut as a gemstone.
Elbaite is a sodium lithium aluminium borosilicate hydroxide mineral that belongs to the Tourmaline Group of minerals the following crystals belong to this mineral, Indicolite, Paraiba, Pink, Purple, Rubellite, Verdelite and Watermelon Tourmaline.
Dravite is a rare complex sodium magnesium iron boro-aluminium silicate
Schorl is a sodium iron aluminium boro-silicate hydroxide.
Uvite is a rare calcium iron magnesium aluminium boro-silicate hydroxide.
