Tanzanite is pleochroic, which means that it shows different colours depending on the viewing angle. In order to get the preferred blue or violet-blue hue, gem cutters must properly orient tanzanite gemstones. The vivid blue of tanzanite can rival fine sapphire and makes tanzanite an extremely desirable gemstone
