This may be small, but quite different for the area. Pale pastel green gem on the upper half and colorless clear on the lower half, very rare kown as "achroite". With complex termination as well. This specimen is 1.5 cm (11/16") high by approx. 0.3 cm across. From Paig Mountains. Paprock, Nuristan, Afghanistan. A neat little thumbnail.  These came out of one large pocket back in 1993 -1994 and no more have been found since to my knowlege.This is cutting material saved from the saw.
