Opal belongs to the mineral group known as silicates, specifically classified as a mineraloid due to its amorphous nature and lack of a crystalline structure. It is primarily composed of silica (SiO2) and water, which contributes to its unique play of color. Opal is often formed from the deposition of silica-rich solutions in geological environments.
