Calcite

This exceptional specimen features a striking pair of intergrown, crisscrossing scalenohedral calcite crystals, partially coated with what appears to be white albite (though this identification is not confirmed). Under UV light, the specimen displays a beautiful range of colours, from white-blue to pink fluorescence. Acquired by Dr. Peter Tarassoff in 1992 from collector Gérard Hainnault, who originally recovered the piece, this is classic old material that is now rarely seen on the market. A distinctive and highly aesthetic example.

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.
