Fluorite with Sphalerite

specimen number:
2013102

location:
Hill-Ledford Mine, Hardin Co., Illinois, USA

description:

Lovely rosy purple translucent crystals of fluorite measuring to 5.0 cm on edge set aesthetically up on a crystallized sphalerite matrix. Very slight micro-damage present, I think that this is in very good condition. The color is outstanding.  The specimen comes with a framed painting of the specimen by Don Edwards.

The Hill Ledford Mine, located in Hardin County, Illinois, was part of the Illinois Kentucky Fluorspar District, a region historically important for its production of fluorite from vein deposits hosted in limestone. Mining activity in the area took place primarily during the mid 20th century, with underground workings developed to follow mineralized zones rich in fluorite and associated minerals such as calcite, galena, and sphalerite. The deposit formed through hydrothermal processes that introduced fluorine rich fluids into fractures within the host rock, creating well defined veins. The Hill Ledford Mine is especially known among collectors for its distinctive fluorite, which often displays a rosy purple color in well formed cubic crystals, sometimes with good transparency and zoning. These specimens formed in open cavities where conditions allowed for slow crystal growth, and they are valued for their color and aesthetic appeal within this classic mining district.
