Opal

Opals are formed from silica-rich solutions that seep into cracks and cavities in rocks. Opals can also form in fossils, creating opalized fossils. These fossils may include shells, bones, and wood that have been replaced by opal. The most distinctive feature of opal is its play-of-color, which is the result of microscopic silica spheres diffracting light. This phenomenon produces a vibrant array of colors that can change as the gemstone is moved. Opal is traditionally associated with love, passion, and hope. In ancient times, it was believed to bring good luck and protect against diseases.
