Arsenopyrite (large crystals) (ex Chet Lemanski Collection)

Item Description

A striking and eye-catching display quality specimen from Panasqueira featuring rather large, very sharp, highly lustrous, metallic, silvery colored blocky crystals of Arsenopyrite, with minor Siderite. The large group at the top of the specimen measures 3.9 cm, which is bigger than most Arsenopyrites I've seen from the locality over the years. This piece is in excellent shape, with minimal damage, even the places where the piece was detached from the pocket wall have been at least partially overgrown by Siderite, so you don't really see much in the way of actual damage. A really attractive and impressive specimen from this historic and classic locale. Priced at $1,800 in the inventory. From the collection of Chester ("Chet") S. Lemanski Jr. of Browns Mills, New Jersey (https://www.mindat.org/user-461.html). Collection #13340CL. 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.
