2. Hardness: It has a Mohs hardness of about 5.5 to 6.5, making it somewhat softer than quartz.
3. Density: Its density ranges from 1.98 to 2.25 g/cm³.
4. Optical Properties: Opal can exhibit a play of color, known as opalescence, which is caused by the diffraction of light within its silica spheres.
