Great pyrite sun in a stand from Peru

A pyrite sun from the mineral-rich regions of Peru. Characteristic radial-spoked structure in golden pyrite color, a flat disk shape that is clearly visible in the stand.

Pyrite suns form in slate deposits where the mineral pyrite (FeS₂) can grow radially in confined cavities. The layer-compression of the surrounding sediments forces the crystals into the flat-spoked disk geometry.

The Peruvian deposits, especially in the Sparta region, are considered the best source for fully formed pyrite suns. The golden metallic luster is stable above a Mohs hardness of 6 when stored dry.

A collector's item with documented growth geometry, full metallic brilliance and a calm presence in the stand.
