Zoisite occurs in a number of varieties ,the most sought –after being tanzanite ,a variety coloured sapphire –blue by the presence of vanadium. Tanzanite crystals have distinct pleochroism,showing either purple ,blue or slate-grey depending on the angle they are viewed from .There may also be a slight colour change in incandescent light (such as that from a light bulb ) ,when stones may appear more violet .A massive green variety of zoisite ,containing rubies and occasionally dark horn-blended inclusions, may be polished ,carved or tumbled to make ornaments,or an attractive decorative stone. Thulite a massive ,pinkish red variety colourd by manganese ,is also polished or carved to make small ornaments .Tanzanite has been confused with sapphire ,and thulite with rhodonite .Some heating of zoisite varieties may enhance their colour .
