Common Opal

Common Opal is a form of hydrated silica that appears as a semi-transparent or opaque mineral with a milky or pastel hue. It lacks the vibrant play-of-color seen in precious opal, and is often found in volcanic or sedimentary rocks. Its structure contains water molecules within silica spheres, giving it a unique look and feel. Common Opal is valued more for its aesthetic qualities and variety of colors rather than for gemstone use, making it popular for decorative objects and jewelry settings. It’s durable but may contain internal flaws or inclusions, contributing to its varied appearance.
