Smithsonite

Kelly Mine smithsonites are among the most iconic and cherished examples of the species, widely regarded as the finest smithsonites from any U.S. locality. The best specimens showcase one of the most captivating blue hues found in the mineral world.

This specimen is a small cabinet piece featuring vibrant "Kelly blue" botryoidal aggregates with a silky lustre. The translucent, bubbly formations cover a limestone matrix. The blue smithsonite overlays an earlier layer of gray or colourless smithsonite, an exceptional miniature piece.

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.
