Mineral Specimen - E-436 - 30 x 20 mm - $10.00
A single 9mm long calcite is perched atop a partial fluorite crystal. Some bitumen is also present (see bottom left corner of specimen). The "partial" fluorite is the result of what looks to be both etching and contact later on. The calcite looks like it is just the slightest tipped at the top termination - this is not really visible and I don't think it would affect judging if such a specimen were used for competitive displays. Nice combination thumbnail from the Elmwood mine shaft.
