This is a very nice halite specimen. It is extremely transparent, and part of the crystal is colored blue from three orthogonal planes of parallel color-defect zoning. The blue color is a crystal ion defect effect - it would disappear if the specimen was disolved. Five surfaces are cleavage, and one looks fractured - there are apparently no original crystal surfaces. Still, the specimen is appealing. From one side, there are a dozen or more horizontal blue zones. From the front, there are additional parallel blue zones at a 45 degree angle. And from the top, there is a cross-hatch of color zones at right angles. This is a very nice cabinet specimen.
