Koroit opals come from southwestern Queensland, Australia, specifically the Koroit opal field near Cunnamulla. They're a type of boulder opal known for intricate, web-like patterns and vivid flashes of color 🌈.Photo credits: Bali Opal

Koroit opals are a unique type of boulder opal found only in a remote part of Queensland, Australia 🇦🇺, near the tiny outback town of Koroit. They form inside ironstone rock, deep in the ground, where mineral-rich water once flowed through ancient cracks and cavities.

Koroit is a subset of the boulder opal family. And this is one hell of a rock! Just try to find one of these on the Internet ... I dare you.
