OKI-577 Siderite Poudrette Quarry, Mt. St-Hilaire, Quebec, Canada. Ex. Dr. Steve Chamberlain Collection. A fine example of a MSH classic. This siderite twin measures 2.8 x 2.6 x .7 cm, is mildly translucent and has only the most minor of matrix contacts (mostly crystallized here too). No damage and spectacular form. I think these specimens are the most interesting and important siderites from North America and can compete with those from almost anywhere in the world. Even better in person. 80$
