Rhodochrosite, Manganite

Rhodochrosite can be found at many of localities around the world, however specimens from the Moanda Mine in Gabon are exceptionally rare. This beautiful miniature specimen, dating back to the 1970s–1980s, hails from the historic Moanda Manganese Mine and features lustrous, gemmy to translucent cherry-red to brownish-red scalenohedral rhodochrosite crystals with steep terminations. These striking crystals vill a vug in the manganite ore matrix.

Rhodochrosite from Moanda is considered to be an uncommon occurrence, and specimens from this classic find are seldom seen on the market today. The deposit has not produced comparable material since, making this a valuable addition to any comprehensive Rhodochrosite collection. This piece is both visually striking and an excellent subject for close-up examination under a microscope.

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
