What a hue! We recently shared another lovely crystal of Tanzanite (see http://on.fb.me/1B8IMQy for my original post on this mineral) that displayed the multiple colours of its pleochroism, the property some crystals have of displaying multiple colours from different angles (see http://on.fb.me/1DWqeoo). In this image, the single, most perfect shade has come to the fore, in a 8cm long crystal that was nicknamed 'The Deep Blue'. Loz. Image credit: Malte Sickinger

Beautiful Tanzanite I don't think I've ever seen as rich a blue in a zoisite as this 10 cm specimen on matrix from the Merelani hills of Tanzania. While it has almost certainly been heated to bring out the colour (natural blues only happen when heat has been an immediate part of their geological adventure through deep time), the depth of saturation (pink for example is a light red) and perfection of tone (neither too light or dark) make this a gem to be admired.
