Iridescent Goethite

This goethite formed in the oxidized zone of iron-rich deposits, where mineral-laden waters precipitated layered growths of iron oxide. The iridescent colors developed from thin surface films that refract light, creating shifting hues across the metallic surface. The Bukit Ketata area is known for producing striking specimens with vivid natural coloration.

Shimmering with rainbow tones over a dark metallic base, this specimen reflects both chemical weathering processes and the natural optical effects that make goethite especially captivating.
