This is a pristine, perfectly terminated, brightly lustrous gem quality tanzanite crystal in a luminous shade of cornflower blue.  Viewed from the side, the color changes to blue violet because the crystal is pleochroic.  There is no damage to the see-through termination. This is a naturally blue crystal, and it has not been heat treated.  The crystal is clear enough that you could easily cut a gemstone if you did not want to preserve the crystal.
