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.
Corundum is a crystalline aluminum oxide and comes in a range of colours. Corundums are more commonly known as includes rubies and sapphires. The name "corundum" is derived from the Tamil word Kuruvindam or Sanskit word Kuruvinda meaning ruby.
The red variety of corundum is Ruby. Padparadscha is the name for a rare orange-pink variety and has a higher value than blue sapphires. Sapphire is the name given to the rest of the Corundum family whose colours include yellow, green, white, colourless, orange, brown, and purple. Blue is the most popular colour for sapphires.
Sapphire is the birthstone of September. It is also one of the birth stones for the Zodiac signs Pisces, Taurus, Virgo and Sagittarius. Sapphire is given as a gem for the 5th, 23rd and 45th wedding anniversaries while a star sapphire is given on the 65th wedding anniversary.
Tanzanite was first discovered in Tanzania, East Africa and is part of the Zoisite mineral species and is only found in East Africa.
Legend says it was Masai cattle herders that first noticed Tanzanite some 30 years ago after a fire caused by lightening burned areas in Tanzania. The herders noticed that brown zoiscite crystals had turned a deep blue-purple due to the heat from the fire.
While Tanzanite is often a blue colour when first mined it is very rarely a pure blue and usually exhibits rich purple overtones. It can also be brown and is routinely heat treated to permanently draw out its exotic bluish-purple colour.
Pure topaz is colorless and transparent but is usually tinted by impurities; typical topaz is wine, yellow, pale gray, reddish-orange, or blue brown. Imperial topaz is yellow, pink (rare, if natural) or pink-orange. Brazilian Imperial Topaz can often have a bright yellow to deep golden brown hue, sometimes even violet. Naturally occurring blue topaz is quite rare and generally, colorless, gray or pale yellow and blue material is heat treated and irradiated to produce a more desired darker blue.
Blue Topaz is generally graded based on the quality of the colour with Swiss Blue Topaz being a lighter sky colour and London Blue Topaz being a darker stormy blue. Both forms are present and I am led to believe they are natural.
Blue Topaz Stones aid spiritual communication, help writers block and inspire creativity and enhanced public speaking.
