"Pleochroism" - the ability to see different colours from within a stone, depending upon the angle it is viewed from, is certainly applicable to the tanzanite. The colours of purple, blue and sage green can all be seen. To try to just bring about the blue and violet-blue shades these stone are heat treated to about 500-700 degrees C. This process used to enhance the colours that are present is said to be a permanent process, so it is universally accepted within the jewellery trade that just about all tanzanites sold today have been treated in this way. Because of the amount of internal inclusions that may be present, it is very important that they are not over heated, due to the increased chance of the stone splitting.

The working of tanzanite stone from the rough to the polished and finished example, can be a bit of a problem to even the most skillful of cutters. The colours can be left very pronounced when viewed from one angle, to quite poor when viewed from another, so the cut is so really important. This gem is cut into all manner of shapes, so as to show of its wonderful colour changes to good proportions.

Only those people who are confident enough to wear gemstones consisting of these captivating a rich colours, should consider the acquisition of such jewellery. Women of all ages can surely want nothing more than one tanzanite that is perfectly cut, and demands the attention of all. Its no good being a shy and retiring type if you want to wear this stone. You have to be confident with yourself and the world around you.

Most often the official grading systems that is used is that of the GIA (Gemological Institute of America) when it comes to colours of most gemstones, but a more simplistic grading range can be thought to be triple A to B, with triple A being the best in quality and that of a deep blue-purple, down to B being a light ultramarine shade.

The very best tanzanite gemstones are now unofficially known as being that of quadruple A colour, which is an example that shows the deep blue centre and lighter violet halo surround. This term was invented by the miners who found these gems to separate them from in their minds, the lesser triple A examples. This quadruple A terms has been taken over largely by the television jewellery channels.

Whichever the colour of tanzanite you may have in jewellery, then just remember it is a relatively delicate gemstone when compared to sapphires and rubies, so it does require a little care, and protection from knocks etc. If you keep it clean by washing in mild soapy water with a soft toothbrush, and wipe off with a clean and sort cloth when needed, it will remain as beautiful as it was when first purchased for evermore.

I hope you just have enough confidence to show it off to its optimum..,
