The blue tanzanite represented by this lot weighs over 6 carats. The main advantage of the stone is its deep blue color, which practically does not contain a violet hue, which is very valuable for natural tanzanites. The specimen is of high purity and does not contain cracks or inclusions. The cut quality is good. This specimen resembles a precious blue sapphire, which is several times more expensive than tanzanites.
