Tourmaline is a stone with unusual features. It surpasses any other one in the variety of its color. The stone got its name in Europe at the beginning of the 18th century, when Dutch sailors began to bring various precious stones from the island of Ceylon (Sri Lanka) to Amsterdam, and among them golden columnar crystals, which the inhabitants of the island called “turmali”.
Tourmaline gem description:
Place of mining:
The main share of tourmalines of different shades of gem quality is supplied to the world market from Brazil. More than half of all tourmalines are mined there. In this country, most of the deposits are located in the state of Minas Gerais. Of the African countries mining the mineral, Mozambique, Nigeria, and Madagascar can be distinguished. The expensive copper-bearing Paraiba tourmalines are now mined mainly in Mozambique. Tourmaline is also mined in Afghanistan, Pakistan, Tajikistan, Italy, and the USA.
Crystals of the gem often look like prisms with longitudinal shading. And the cross-section of crystals usually looks like a spherical triangle. The hardness is quite high (7-7.5); they can be safely used in jewelry.
There are two independent classifications of its minerals group:
crystal-chemical - the stone was named based on its chemical composition and crystal structure;
color classification - often used in gemology and commerce. In nature, there are over 500 varieties of this mineral. We give a short description of the best of them, which are also in our catalog.
It is a rare and expensive type of tourmaline, classified as a gemstone. Iron impurities give the mineral a deep blue color. Extremely rare specimens with a dark blue tint of crystals are used to make luxury jewelry.
The content of manganese causes the bright color of rubellite. The color gamma of rubellite is very wide: from the color of the tea pose to the dark purple. The most valuable are the crystals of bright red and ruby color.
First discovered in the 1980s in Brazil, in the state of Paraiba. This type is considered the most expensive type of mineral. This copper-colored stone has its own unique bright "neon" blue, green and blue-violet colors. By its composition, it is considered an elbaite.
This is how the Italians call the green color. It is a very widespread kind of tourmaline, that is externally reminiscent of emerald. The most expensive and beautiful verdelites, which have an emerald-green shade, are named "Brazilian emeralds".
Polychrome and watermelon
In addition to the specimens mentioned above, painted in one shade, there are polychrome (multi-colored) tourmalines. It is characteristic of this species that two, three, or even more colors can be observed with the naked eye in the identical crystal. For instance, it can be a watermelon tourmaline. This species got its name due to the original color of the crystals, which makes them look like a slice of watermelon.
