Discover the Breathtaking Opal Gemstone Called 'Rainbow Tree'

This Beautiful Boulder Opal Called the 'Rainbow Tree' From Queensland, Australia will blow your mind. Rainbow tree opal is a type of opal that is characterized by its colorful bands that resemble tree trunks. It's so amazing to see these natural pieces of crystal, created from the Earth. Some of them thousands of years old, crystallizing and taking form.

It is formed when water containing silica minerals seeps into cracks and cavities in rocks, and then evaporates, leaving behind the silica. The silica then crystallizes into opal, and the colors are created by the way that light interacts with the different layers of the opal.

Rainbow Tree opal is formed in sedimentary rocks that have been subjected to heat and pressure. The rocks are typically sandstone or shale. The opal is formed when water and silica are dissolved in the rocks and then deposited as the rocks cool.
