OKI-577

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$
