A truly outstanding crystal in so many ways! It has, first and foremost, super form and the sharpest crystallization you can ask for in a termination. It is GLASSY in luster, and complete free of damage. It is NATURAL and unheated to enhance the blue color at the expense of the c-axis red/maroon hue that you can get in natural crystals - this is clearly visible, though hard to photograph, in a shot in the bottom-right showing the c-axis red color quite clearly. Thus, this is a natural trichroic crystal exhibiting purple, blue, and red colors. It is more obvious in person. Lastly, it has a little bit of white rock matrix, with small brilliant specks of graphite crystals, anchoring the base of the tanzie! 3.6 x 2.4 x 0.8 cm
