This specimen features slender pseudo-hexagonal strontianite crystals (the field of view in this first photo is 2.0 cm). The stronianite crystals are sharp and as lustrous as strontianite gets, with the cyclic twinning patterns visible at the terminations. In excellent condition, a few incomplete crystals around the periphery where this specimen was removed from surrounding rock. Stands perfectly for display as photographed. These are pretty strontianite crystals.
About these Strontianites
These strontianites are from the collection of Franz Lammer (1914-1997), and were collected during the period approximately 1967-1992. Although strontianite is a relatively common mineral, it is difficult to obtain fine collection specimens of sharp crystals. Among the finest ever found are the specimens that came from the magnesite deposit at Oberdorf an der Laming, Styria, Austria, a locality that has produced superb crystals of a few different habits.
