Fluorite crystals are well-known from Baveno, in Piedmont, northern Italy, where granite quarries have operated since the 16th century, but those crystals are usually microcrystals and on very small specimens. Not only is this specimen larger, and features a substantial (1.4 x 1.4 cm) aggregate of purple modified cubo-octahedral crystals, but it is centuries old too! It comes from the fine systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021) and is accompanied by two late 19th century handwritten labels one of which is particularly beautiful and detailed. The Fluorite crystals are colour-zoned from purple to almost colourless in parts, and are perched upon a classic white Orthoclase matrix with some crystals but which are not perfect in their shape. It is, nevertheless, a very fine historic Fluorite from this famous region of Italy.
