Opals are processed exclusively into gemstones. The word opal was borrowed from Latin opalus or the Greek ὀπάλλιος opallios for ‘precious stone’ and presumably goes back to upala in Sanskrit. According to Allan W. Eckert in his work The World of Opals, it was used to denote various rocks, while the early Hungarians called opálbánya opal mines. Opals were already considered especially valuable gemstones in antiquity, sometimes even valued higher than diamonds. Pliny the Elder wrote about it: ‘... it has a fire of its own, finer than that in the carbunculus, it possesses the purplish spark of amethyst and the sea-green of emerald and an altogether incredible mixture of light.’ Shipping as insured registered mail.
