The rich colour of the finest tanzanite is quite unique in the gemstone world and in the case of tanzanite, colour is so important that it outweighs almost all other grading considerations.

In exceptional tanzanites, the colour is an intense violetish blue with red flashes of pleochroic colour coming from within the stone. Due to the gem’s strong pleochroism, fashioned examples typically show a mix of both blue and violet colours in a wide range of tones. As with most coloured gemstones, paler colours are more available and affordable than saturated ones.
