Fluorite

This specimen features a stunning, water-clear, light-green fluorite crystal with a cube-octahedral habit. Exceptionally transparent and lustrous, this piece exemplifies the high-quality fluorite found in the long-depleted Rogers Mine near Madoc, Ontario. Although only part of a crystal, its clarity and brilliance make it a remarkable old-stock example from this classic locality. Specimens from this locality are challenging to photograph due to their exceptional transparency, glassy surfaces, and satin lustre. With the mine long closed, high-quality pieces like this are increasingly rare, making it a valuable addition for collectors specializing in Canadian fluorite or classic localities.

This specimen comes from the collection of Dr. Peter Tarassoff, a prominent figure in mineralogy, particularly known for his work at Mont Saint-Hilaire (MSH). His diligent collecting and examination efforts have led him to be the first to identify at least 35 species and discover 12 new species, not only at MSH but also at other alkaline localities. Dubbed the "Dean" of Mont Saint-Hilaire collectors, Peter was honoured with the naming of the new species petarasite in 1980. He has authored or co-authored numerous mineralogical articles and has been a member of the Mineralogical Association of Canada since 1964. Additionally, Peter has volunteered at the Redpath Museum for the past 21 years, where he was formally appointed the Honorary Curator of Mineralogy. In recognition of his significant contributions to mineralogy, Peter was awarded the 2017 Pinch Medal
