A very unusual pseudomorph of calcite, which has altered to fluorapatite, from the Foote Mine, in Cleveland Co., North Carolina, USA! This specimen features several of these interesting pseudomorphs that have formed upon a matrix of albite. The crystals are actually hollow, which would make them epimorphs. The fluorapatite fluoresces a deep red under LW UV. The specimen is in great condition overall, and displays well. The Foote Mine began operations in about 1938. It is famous for rare phosphates and silicates, boasting an impressive list of over 150 species! In it’s prime, the Foote produced some of the finest fluorapatite and bikitaite in the world, along with many other minerals such as rhodochrosite, lithiophyllite, roscherite, fairfieldite, childrenite, etc. The mine has since ceased operations and is now flooded. Material from this rather obscure U.S locality is very hard to find on the market today, and typically consists of small micromounts. Comes with a custom acrylic base. Ex. Jack Eaker Collection.
