Large specimen with dozens of embedded brassy Pyrrhotite
crystals. The name is derived from Greek pyrrhos, flame-colored.
Numerous lustrous dark red hexagonal Vanadinite crystals form a dense diagonal path across this specimen.
Vanadinite is mineral belonging to the apatite group of phosphates, with the chemical formula Pb5(VO4)3Cl. It is one of the main industrial ores of the metal vanadium and a minor source of lead. A dense, brittle mineral, it is usually found in the form of red hexagonal crystals. It is an uncommon mineral, formed by the oxidation of lead ore deposits such as galena. First discovered in 1801 in Mexico by the Spanish mineralogist Andrés Manuel del Río in 1801 (From Wikipedia, the free encyclopedia).
