Kyanite is a blue coloured silicate mineral, even the name is derived from the ‘kyanos’ which means ‘deep blue’. It often forms in pegmatites and so is found along side other minerals such as quartz and feldspars, its presence will often indicate a high pressure metamorphic environment, and being one of few, is also used as an index mineral when determining metamorphic depth and pressure. Such details as this allow geologist to build up a picture of plate tectonics over a period of given time. It has a bladed crystal habit, which can be easily seen in our images, however the blades are fragile and can break easily if handled harshly. Specimens may also show quartz. These pieces come from Botswana in Africa, and have a much paler blue colouration when compared to our Brazilian specimens.
