More information
Found worldwide, with notable specimens from Peru, Spain, and Brazil, it is an association of quartz and pyrite crystals, both precipitated from hydrothermal fluids during the same vein-type mineralization phase. The contrast between the transparency of quartz and the golden metallic luster of pyrite creates a highly sought-after aesthetic effect.
This specimen is highly prized by collectors for the visual contrast between the two minerals; it is used in decoration and displays; it is also of educational interest for illustrating mineralogical paragenesis.
