This specimen features sharp, pseudo-cubic, colourless crystals of fluorapophyllite-(K) from the large quarry at Mariánská Skála (formerly Marienberg) in Ústí nad Labem, Czech Republic. The well-formed, lustrous, blocky white crystals, measuring up to 4 mm, are richly distributed across a vug in volcanic rock, likely phonolite, with only minor bruising.

Mariánská Skála quarry is a prominent geological feature on the left bank of the Elbe River and has been an active quarry for many years, contributing to its reputation as an important mineralogical locality. The rock is a sodalite-natrolite-rich laccolith, with natrolite comprising an approximately 40% of the formation. In addition to fluorapophyllite-(K), the quarry has produced excellent examples of zeolite minerals making this a significant and diverse mineral deposit.

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. All specimens from this collection come with the original P. Tarassoff collection label.
