Geometric Transformation – Limonite After Pyrite

A fascinating and sculptural specimen from Colombia, where limonite has replaced the original pyrite crystal while perfectly preserving its sharp geometry. The intergrown cubic forms are so harmoniously unified that they create the appearance of a single, sculptural sphere.

The transformation reveals a rich metallic-brown sheen and a delicate texture unique to limonite. With its bold symmetry and architectural beauty, this piece feels almost hand-crafted — a natural sculpture shaped by time, chemistry, and the artistry of the Earth itself.
