Zebra rock (or zebra stone) is a unique, fine-grained siltstone from Western Australia's Kimberley region, known for its distinctive, naturally occurring reddish-brown and white stripes or spots, formed from quartz, sericite, and iron oxide (hematite) over 600 million years ago. Its patterned formation results from self-organizing chemical reactions, making it a significant geological specimen used in jewelry, aquascaping, and as a collector's item, though it's also found in other locations with similar banding.
