This specimen is a classic cluster of calcite rhombohedrons from the renowned, now-closed Tsumeb Mine. The piece displays sharp, glassy, colourless calcite crystals that vary from translucent to transparent. Lustrous, rhombohedra cover the piece, accentuated by sparkling micro-dolomite crystals preferentially encrusting the sides of some crystals. As well, scattered olive-green duftite, appears as inclusions and surface coatings on some of the calcite. The calcite crystals at the base are clearer near the top, and becoming more opaque toward the top, creating a captivating visual gradient. The selective micro-dolomite encrustation on some rhombohedral faces adds texture to the specimen.

Dr. Tarassoff acquired this piece from the Mineral Kingdom of Woodmere at the Tucson Gem and Mineral Show in 1980. This specimen embodies the unique mineralogical diversity of Tsumeb, capturing a fine blend of crystal clarity, subtle colour contrast, and intricate associations characteristic of this famed locality.

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 by the Mineralogical Association of Canada.

Peter's dedication to systematic collecting, curating his collection, and maintaining an archive of detailed historical and scientific information has greatly benefited the mineral sciences community both in Canada and globally. All specimens from this collection come with the original P. Tarassoff collection label.
