Yellow fluorite from Chaillac (Indre 36)

Discover some photographs of honey fluorite from the Chaillac mine in the Indre department (36). This specimen also contains galena, a lead sulfide..

Fluorite from Chaillac, in the Indre department, is one of the most famous in France due to the abundance and quality of the specimens discovered in the former barite and fluorite deposit. The crystals generally take the form of well-developed cubes, ranging from a few millimeters to several centimeters in size, in a wide variety of colors: intense purple, golden yellow, green, blue, sometimes zoned with spectacular combinations of hues. The translucency to transparency of certain specimens, combined with concentric zoning or internal ghosting, gives them a remarkable aesthetic appeal. Fluorite is often found in association with tabular barite, hematite, quartz, or galena, forming assemblages that are highly prized by collectors. Some specimens also exhibit blue fluorescence under UV light, enhancing the mineralogical and visual interest of this deposit, which has become a true global benchmark.
