Iron Cross

Regular price $120.00

This fascinating piece is a limonite twin pseudomorph, meaning the iron oxide mineral limonite (or goethite) replaced a twinned crystal, most commonly pyrite, while retaining the original, complex, or cross-shaped habit.

These replacements, famously occurring as "iron cross" twins from Gachalá, Colombia, show a brown, weathered exterior while preserving the structural, often cubic or dodecahedral symmetry of the original mineral.
