This stunning specimen impresses with an extraordinary gypsum swallowtail twin on contrasting anhydrite matrix. Its special feature are water-clear strontioginorite crystals, a rare borate mineral found in only a few locations worldwide. The Kohnstein quarry is considered the most important site for this particular paragenesis. Since the site now yields hardly any new material of this quality, this specimen is a valuable piece of documentation.
The clear aesthetics and the rarity of the crystal combination make this specimen a valuable addition to any systematic German mineral collection. An authentic exhibit for connoisseurs who appreciate site-specific characteristics.
