LARGE TANZANITE

NONE OF THESE SPECIMENS HAVE BEEN HEAT TREATED, POLISHED OR OTHERWISE TREATED IN ANY WAY. EVERY ONE IS 100% NATURAL, GUARANTEED!

Due to the nature of photography, some of the pictures do not show the di/tri-chroism colour variations accurately (if at all), i.e. All specimens exhibit the purple and blue colours on the x and y axis, but this is not necessarily shown in the photographs.

Dimensions accurate to .05 of a cm, weights to 0.1 grams or 0.5 carats.
