This piece hosts an absolutely superb strontianite crystal – it is a sharp textbook pseudo-hexagonal crystal showing cyclic twinning. Upon examination, you can make out the “snowflake” pattern on the termination. The prism faces are lustrous with striations, and the crystal is 0.9 cm tall. In excellent condition, no damage visible without magnification (a very minor abrasion can be detected searching with a loupe). This is a beautiful strontianite crystal.
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.
