More Information
Tanzanite   is an extraordinary gemstone. It occurs in only one place worldwide   -Tanzair africa. Its blue, surrounded by a fine hint of purple, is a   wonderful colour. Thanks to its unusual aura and the help of the New   York jeweller’s Tiffany, it has rapidly become one of the most   coveted   gemstones in the world.
Tanzanite   is a blue variety of the gemstone zoisite. It consists of calcium   aluminium silicate and is not particularly hard, having a value of 6.5   to 7 on the Mohs scale. For that reason, it should always be worn   carefully and never placed in an ultrasonic bath for cleaning or brought   into contact with acids.
The   deep   blue of the tanzanite is fantastic, and runs from ultramarine   blue to   light violet-blue. The most coveted colour is a blue   surrounded by a   delicate hint of purple, which has a particularly   wonderful effect in   sizes of over 10 carats. The well developed   polychromaticity of the   tanzanite is typical: depending on the angle   from which you look at it,  the stone may appear blue, purple or   brownish-yellow. Having said that,  most raw crystals are somewhat   spoiled by a brownish-yellow component,  though it can be made to   disappear by the cutter if he heats the stone   carefully in an oven to   approximately 500°. During the procedure he must pay careful   attention to the moment at which the colour turns to blue.  This   burning is a method of treatment which is regarded as customary in   the trade, but the raw stones must be as free of inclusions as   possible,  since otherwise fissures may occur. In fact working with   tanzanite can   sometimes give even the most experienced cutter a bit   of a headache,  the cleavage of this gemstone being very pronounced in   one direction.  This exclusive gemstone is cut in every imaginable   shape from the classical round shape to a number of imaginative   designer cuts.
