This specimen features sharply formed seafoam green scalenohedral zincolivenite crystals, accompanied by darker transparent colour-zoned bayldonite from Tsumeb, Namibia, renowned for producing some of the finest examples of zincolivenite. Zincolivenite, often classified alongside adamite, forms through a complete chemical series between zinc-rich olivenite and adamite, explaining its similarities in structure and coloration. Prior to its formal classification, specimens of zinc-rich olivenite were commonly referred to as "Zn-olivenite" or "cuproadamite," with zincolivenite later confirmed as its own distinct species in the mineral series. This specimen was purchased by Dr. Tarassoff at the Montreal Gem and Mineral Show in 1992.

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.
