The opal is a mineral from the mineral class of the “oxides and hydroxides.” As an amorphous solid, opal (similar to glass) has no crystal structure and typically appears as massive vein fillings or nodular formations.

Opals are exclusively processed into gemstones.

The word opal was borrowed from the Latin opalus or the Greek ὀπάλλιος opallios for ‘precious stone’ and likely derives from upala in Sanskrit. According to Allan W. Eckert in his work The World of Opals, these terms referred to various rocks, while the early Magyars called opal mines opálbánya.

Opals were already regarded in antiquity as particularly valuable gemstones, sometimes valued even higher than diamonds. Pliny the Elder wrote about it: “[…] it has a fire of its own, finer than that of the carbunculus, it possesses the purplish spark of the amethyst and the sea-green of the emerald and an utterly incredible play of light.”
