A southern Illinois classic, a mass of transparent, gemmy Calcite crystals are the sparkling background to some small purple to blue Fluorites. The bright luster of these Calcites are hard to appreciate in photos but in person the visual impact is strong. This choice Denton Mine specimen is from the collection of Les Hitchings which he obtained in 1992, from the last period of mining there which produced some exceptional Calcites.
Remarkable dark purple Fluorite crystals that have a bright yellow core that is only seen inside the holes left by former Barite rosettes. These Barite holes have a distinctive structure, these are a waxy cone shaped void that shows the detail of the long-gone Barite crystals. These Barite holes are well known from the region but the color zoning on this one is unusual and is especially impressive when backlit. The Fluorite is overall dark, sharp and lustrous with some edge scuffs, so perhaps not for strict perfectionists. The main interest is of course the Barite holes up to 1 CM across that penetrate the inner bright yellow center of the Fluorite.
A sharp multi-color pastel Fluorite with good clarity and phantoms. The crystals show excellent growth patterns and have sharp crystals of golden Chalcopyrite included inside. This looks fantastic with good lighting. A classic locale, the Denton Mine once produced a lot of good Fluorites, but is now gone forever. Some color changing based on light source, the core color is a pale yellow with blue to purple outer phantoms.
