“Calcite crystals (previously labelled as strontian aragonite crystals). Coll. & photo: Giuliano Bettini. Modified by CombineZP. The child photos show the same crystals under visible and long-wave UV light (observed under the microscope). NOTE: Boccheggiano is one of the most important historical Italian localities for fluorescent minerals, which yielded literally tons of the so-called “strontian aragonite” or “aragostrontianite”, a carbonate material fluorescing red under LW-UW and desaturated peach-red SW-UW. Simeone (1980), in a short note, pointed out that the name locally used by mineral collectors is misleading and the fluorescent material (varying in color from white to dark green and appearing as individual scalenohedral crystals, mammillary and fibrous-radiating aggregates, etc.) consists of calcite. Later studies have evidenced that the carbonate material is mainly made of calcite, but also its polymorph aragonite exists at Boccheggiano (and cases where the two phases coexist in the same specimen are quite frequent); the fluorescence of the two polymorphs is pratically the same. Studies on the Boccheggiano carbonate minerals are in progress. Mazzoleni (2010) published some photos of these carbonates: scalenohedral semitransparent crystals of calcite in association with white globular aggregates of aragonite (see Photos 352 and 353, page 174); banded calcite specimen with fibrous texture, varying in colour from greyish-green (external layer) to white (see Photos 357-359, page 176); whitish fibrous-radiating aggregate of slender prismatic crystals, up to 40 mm long, of aragonite (see Photos 362-364, page 178).
