Opal cabochons are polished, rounded gemstones cut en cabochon to display opal's characteristic play-of-color without facets. Opal is a hydrated amorphous form of silica, famed for its shifting, iridescent color flashes across the surface caused by microscopic silica sphere arrangements. The size indicated fits common jewelry applications such as rings or pendants. Opals are formed from silica-rich waters percolating through rocks, depositing layers over long periods. The cabochon cut enhances the gem’s optical phenomena and suits the often delicate structure of opal, prized for its beauty and uniqueness in jewelry collections worldwide.
