### Australian Koroit Double-Sided Boulder Opal
A beautiful and unique **Koroit Boulder Opal stone from Queensland, Australia**, featuring natural patterns and character on **both sides**. Each Koroit opal is completely individual, with intricate ironstone matrix creating stunning natural landscapes, patterns and colour contrasts throughout the stone.
Koroit Boulder Opal formed over millions of years as silica-rich water travelled through ancient cavities and cracks within Queensland's ironstone-rich geological formations. Over immense periods of time, the silica gradually solidified into precious opal, becoming naturally intertwined with the surrounding ironstone. This combination creates the distinctive matrix patterns that Koroit Boulder Opal is famous for.
Koroit is particularly sought after by collectors for its **complex natural patterns, earthy ironstone colours and flashes of precious opal**. Unlike many polished gemstones, the beauty of Koroit often comes from the natural landscape-like patterns within the stone, making every specimen genuinely one of a kind.
The **double-sided nature** of this piece makes it especially interesting for collectors, with both faces offering their own unique appearance and detail. It can be displayed as a collector's specimen, incorporated into jewellery, or simply appreciated as a natural piece of Australian opal.
**Key features:**
* Australian Koroit Boulder Opal
* Queensland, Australia
* Natural ironstone and opal formation
* Attractive patterns on both sides
* Formed over millions of years
* Unique collector's gemstone
* Every stone is naturally individual
A fascinating piece of Australian geological history and a wonderful addition to any **opal, gemstone or mineral collection**.
*Please examine the photographs carefully, as the natural patterns, matrix and colour variation shown are part of the character of this individual stone.*
