Here the ADP contains an extreme high amount of chromium which results in an almost emerald like
color (which is no wonder as chromium is the coloring agent in emerald, too !).
Solutions with such a high chromium content tend to produce extreme needle shaped crystals. If that happens
its almost impossible to get such a solution back to "normal".
This specimen is currently exhibited at the mineral museum in Pforzheim.
