Tourmaline is the most colourful of all gemstones and occurs in all colours, but pink, red, green, blue and multicolored are its most well-known colours with blue (Indicolite) being one of the rarer colours.
Liddicoatite tourmaline is a calcium-rich lithium tourmaline, typically exhibiting extraordinarily beautiful geometrically patterned colour zoning usually in the form of triangles or the “Mercedes” star shape.
Scientifically though , tourmaline is not a single mineral, but a group of minerals related in their physical and chemical properties. The mineral Elbaite is the member of the Tourmaline group that is responsible for almost all the gem varieties. Three other members of the group - Schorl, Dravite and Liddicoatite, are seldom used as gemstones.
More than 4,000 naturally occurring minerals (inorganic solids that have a characteristic chemical composition and specific crystal structure) have been found on Earth. They are formed of simple molecules or individual elements arranged in repeating chains, sheets, or three-dimensional arrays.
Minerals are typically formed when molten rock, or magma, cools, or by separating out of mineral-rich water, such as that in underground caverns. In general, mineral particles are small, having formed within confined areas such as lava flows or between grains of sediments. Large crystals found in geodes and other rocks are relatively rare.
Rocks themselves are made of clusters or mixtures of minerals, and minerals and rocks affect landform development and form natural resources such as gold, tin, iron, marble, and granite.
Prasiolite is a form of green quartz. The name is derived from the Greek word prason meaning ‘leek’ and lithos meaning ‘stone’ and literally means ‘garlic green coloured stone’ and was given its name due to its green colour.
Prasiolite is amethyst that has been exposed to heat and while heats usually produces citrine in some cases it turns green and forms Prasiolite. Prasiolite occurs naturally, but is rare and mot comes form from a small mine in Brazil, Lower Silesia in Poland and in the Thunder Bay area of Canada. Often what is sold is treat amethyst and thus it is often wrongly called green amethyst.
Prasiolite is believed to assist you to express personal emotion and help link the energy of the heart with the crown chakra. It is also said to open both the crown chakra and the third eye and activate your inner vision.
