This specimen is composed almost entirely of Ankerite, a mineral that is basically a cross between calcite and siderite. It is in the form of thin fan-shaped, bladed crystals that measure up to 3/4"(1.9 cm) wide and 1/2"(1.3 cm) high. They are off-white in color and have a pearly to silky luster due to subtle but concentrated patterns on their faces. The specimen feels surprisingly heavy for its size- I'll have to ask David about the specific gravity. Even though the blades appear delicate, there is little damage to them except for some that are at the edge of the piece and one that was cleaved near its base. This is a pretty little specimen, even with the dull color- I like the luster of it best of all.
