Muscovite, var. Fuchsite

Specimen # 102714
Mineral: Muscovite, var. Fuchsite
Location: Junco, Malacachetta, Minas Gerais, Brazil
Size: 9.4 x 8.9 x 7.4 cm


Detailed Description

This cabinet specimen features rosettes, books and clusters of individual fuchsite crystals, associated with quartz crystals and a few rutile crystals. From the 2009 find, this is a remarkable piece – there weren’t very many in any case, and most of those were small and not in this league. The colour at a distance is a good green, but under good light and backlighting, upon closer inspection these crystals are a truly brilliant chrome green. In excellent condition for the find, with a few rubs and abrasions. One can enjoy this specimen for a long time with a loupe – as you can see from the photographs!

About these Muscovite, var. Fuchsite, Specimens

Although muscovite crystals are common, freestanding crystals of the chromian green variety, fuchsite, are rare.  Similarly, fuchsite itself occurs not uncommonly, but as foliated masses, only rarely as individual crystals and crystal groups. In 2009, a prospector hit this small find of fuchsite crystals in the Junco District, in Minas Gerais. There were not many specimens and most of those were heavily abraded (mica being so soft), so there were very few truly fine pieces from this find.
