Siderite (ex Chet Lemanski Collection)

Item Description

A beautiful small cabinet display specimen from Leadville featuring gorgeous lustrous "rosettes" of golden colored Siderite sitting on Pyrite matrix. The piece is most likely from the Black Cloud Mine, but there were several mines that produced similar looking Siderite specimens in Leadville, so it's tough to say for certain where it was found. Overall, the piece is in very good condition, as it's mostly damage free on the display side, and the only roughness is around the periphery where it was detached from the pocket. From the collection of Chester ("Chet") S. Lemanski Jr. of Browns Mills, New Jersey (https://www.mindat.org/user-461.html). Collection #18706CL. Chet was born 1947 in started collecting minerals circa 1957. He worked briefly as a drill runner at the famous Sterling Mine, in Ogdensburg, New Jersey and from 1987 to 1990 he helped convert the mine into a public access mining museum. He has held the role of treasurer, vice president and president of the Franklin-Ogdensburg Mineralogical Society (FOMS), and has been a board member and vice president of the Franklin Mineral Museum. The rare copper arsenate, Lemanskiite was named in his honor in 1999.
