The origin of the term opal comes from the Sanskrit word upala meaning "precious stone", which is the origin of the Greek opallion and the Latin opalus.

According to Pliny the Elder :
"Formed from what is worthy of the most precious gems, they have offered infinite difficulties to the description; for in them is found the subtle fire of the carbuncle, the purple glow of the amethyst, the sea green of the emerald; and all these hues shine, marvellously melted.
