MK269 - Coquimbite, Romerite $ 300 South Olga Tunnel, Monte Arsiccio Mine, Stazzema, Lucca Province, Tuscany, Italy miniature - 4 x 3.3 x 2.2 cm Outstanding large purple Coquimbite crystal set in white Alunogen with dark red crystals of Romerite from recent finds at the Monte Arsiccio Mine in Italy. The Monte Arisiccio Mine is an old iron mine that worked Barite, Pyrite, and iron oxide ore bodies. Along with other uncommon sulfate minerals, this mine has produced what are in my opinion the world's best Coquimbite specimens. The Coquimbite crystal is well formed and 2.2cm in size and has incredibly rich purple coloration that contrasts well against the white Alunogen. These specimens should be kept sealed in plastic bags or boxes or otherwise be kept from high humidity or moisture. This specimen comes mounted in a plastic box.
