This 67.36 carat tanzanite crystal is one of the finest (and tallest) specimens that we currently have available. It measures 56mm x 14.3mm x 8.4mm. This piece has a beautiful deep violet blue and a gemmy overall look to the crystal. The color has been enhanced by heating. Rotating the crystal shows an great example of the Pleochroism, when viewed in different angles (as seen in the photos). It's an amazing piece that would look great in any display cabinet.
