Chalcopyrite - Collection 668

Iridescent chalcopyrite from Mexico on a base

Chalcopyrite is a copper and iron sulfide with the formula CuFeS₂, belonging to the tetragonal crystal system. Extracted from Mexican deposits renowned for the quality of their specimens, this iridescent chalcopyrite displays a play of colors on its surface, ranging from blue to violet, including green, gold, and pink. These metallic reflections originate from a thin layer of oxidation formed on the mineral's surface, which diffracts light depending on the angle of observation. Mexico is among the world's leading producers of chalcopyrite, along with Peru and Chile, and regularly supplies specimens sought after for their pronounced iridescence and well-formed crystals.

Each set consists of a raw piece of chalcopyrite, selected for its rich colors. The stone is presented on a base that enhances its iridescence and facilitates display in a showcase, on a shelf, or in a cabinet of curiosities. Dimensions and weight vary from piece to piece due to the natural nature of the mineral: each specimen is unique in its shape, crystal orientation, and intensity of iridescence. Chalcopyrite is a relatively soft mineral, with a hardness of 3.5 to 4 on the Mohs scale, and must be handled with care to preserve its iridescent patina. Simple dusting with a soft brush is sufficient for its maintenance; prolonged contact with water or acidic products should be avoided.

This set of iridescent chalcopyrite from Mexico on a stand is perfect for mineral collectors, Earth science enthusiasts, and anyone looking to add a unique natural piece to their décor. The clear acrylic stand allows the stone to be displayed in a stable and aesthetically pleasing way. Each order is carefully prepared and shipped in protective packaging.
