A very aesthetic, sharp cluster of bipyramidal crystals of thenardite, a rare sodium sulfate, to 4 cm on a side. The display view clearly highlights the main crystal which resembles a spear point. These are generally considered best of species material, and really good ones are seldom seen on the market today.
