Description

Fluorescent Calcite Dolomite  "Strontium Aragonite" 35.5mm Sphere Boccheggiano Mine, Montieri, Grosseto, Italy
Photos 1/2 in UV-LW, 3,4,5 in UV-SW and 6 natural light 

Improperly called "arago-stronzianite" this mineral is actually Calcite, so at least it results from the unequivocal analyzes conducted by Mazzoleni, Dallegno, Menegazzi and published in 2016 by the FMS

The more colour and green on the specimen (in natural light) and more the fluorescence is intense.

In LW the fluorescense is cherry red and in SW  is more dessaturated and the color therefore tends to pink
