A DRAMATIC and showy toenail specimen of the uncommon halide, sal ammoniac, from the 1990 find in Tajikistan. The grayish-white, translucent and lustrous crystals form a very attractive three-dimensional aborescent shape, like branching frost on your window. Incredibly weird species, looking fake! This is a spectacular specimen from the Carl Davis Collection.
