One of the best known species from the European Alps is Titanite (Sphene), and this is a fine example. The main, twinned crystal of grass-green Titanite (included with Chlorite) is 6.9 cm. Attached crossways is a 2.7 cm, doubly-terminated Titanite, accompanied by several sharp, Chlorite-coated rhombs of what is likely Adularia. This may very well date somewhere in the late 19th Century or early 20th Century, based on both history of the area and the fine old label with it. Very good aesthetics. Better in person, by far.
