全部拍賣 / Ethnographic / Gold-colored octahedral pyrite aesthetic with black magnetite
From our selection of collectible minerals, we offer a splendid group of Pyrite crystals with Magnetite from the Brosso Mine, in Piedmont. Furthermore, it is characterized by Pyrite crystals with the typical octahedral habit and brilliant golden luster, in clear contrast with the black Magnetite aggregates coating the matrix, elements that increase its aesthetic value and mineralogical significance. The specimen stands out for the quality of crystallization and for its overall aesthetic balance, with features that enhance its natural structure and visual impact. Pyrite (FeS2) owes its characteristic golden color to its iron and sulfur content, while the typical octahedral habit, as in this specimen, is one of the most common crystal forms for the species along with the cube. The Brosso Mine, in the Canavese area of Piedmont, has for centuries been one of the most important iron mines in the Italian Alps, exploited since Roman times for its magnetite and pyrite skarn deposits. Magnetite (Fe3O4), associated here with Pyrite, is the most magnetic iron oxide in nature and has given its name to the magnetism phenomenon itself. This is an ideal specimen for mineral collections, exhibitions, and for those who appreciate the natural beauty of minerals, even in the field of crystal therapy and lithotherapy, according to the properties traditionally associated with the mineral species. All minerals are 100% natural and untreated, except for rare exceptions always noted in the description. The photographs are taken with professional lighting to best highlight colors and details; however, slight tonal variations may occur depending on the device or ambient light. Shipping is carried out via reliable and selected express couriers, with fast delivery (in many cases 1-2 working days in Europe), tracked and insured shipping and professional and safe packing, as confirmed by customer reviews.
