Calcite with Fluorite, Minerva #1 Mine attr., Cave-in-Rock District, Southern Illinois, ex. Louis Lafayette Collection, Small Cabinet 5.0 x 8.0 x 8.0 cm, $125. Online 10/9.
Group of creamy white spear-point calcite with yellow and light purple fluorite. The mine attribution is very difficult to pin down because this type of calcite is present in adjacent Ozark-Mahoning mines. The same reasoning applies to the mine horizon, hence no attribution. However, it is positively a Cave-in-Rock specimen. Calcite crystals to 3 cm. In fine condition with a couple of tiny cleaves. A pretty piece.
