I would consider this Rajite as one of the better that I have seen. The cyrstals are well defined and the size of the crystals or crystal aggregates are to 1.5mm and the color is from a darker to light green. Rajite is named for Dr. Robert Allen Jenkins (RAJ) and has been found in only two worldwide localities. Excellent specimen!
