Calcite with Marcasite

This striking specimen from the Linwood Mine, Buffalo, Scott County, Iowa, showcases beautifully formed transparent calcite crystals of varying sizes rising gracefully from their natural matrix, accompanied by clusters of iridescent marcasite. The marcasite exhibits a vivid play of gold, bronze, and subtle purple-green hues, creating a spectacular contrast against the pale, luminous calcite.

The combination of clarity, colour, and metallic brilliance gives this piece both visual drama and refined elegance — a perfect balance between strength and delicacy.
