A very gemmy and lustrous tanzanite crystal. This pristine, complete-all-around beauty has a sharp, complex, stepped-growth termination. The 3-sided, pleochroism color of this not heat-treated crystal is classic: the A, frontal face is a very light purple; the B, side face is gray-blue; and the C, vertical axis is reddish-brown. The underlit photo highlights the crystal gemminess and color variations of the C axis. This classic crystal is nicely accented with graphite. The termination is very gemmy and highly representative of the species and locale. Weighs 29.72 carats or nearly 5 grams.
