How is Rainbow Tree Opal Formed?

Rainbow tree opal is formed when silica is deposited around the roots of plants. The silica is deposited in layers, creating a tree-like structure. The colors in rainbow tree opal are caused by the presence of tiny spheres of silica that are arranged in a regular pattern. When light hits these spheres, it is scattered in all directions, creating a rainbow of colors.

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.
