Description

Quartz with pyrite

Cm 5X5X6
SiO₂ (trigonal) + FeS₂ (cubic) — mineralogical association
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.
