Look deeply into the face of an opal and see a kaleidoscope of fiery colors, a veritable galaxy contained within a gemstone that symbolizes hope, love, purity and truth.
The gem name Opal is a derivative of the Sanskrit Upala, defined as ‘precious stone’. Latin Opalus and Greek Opallios means ‘to see color change’.
The beauty of the opal is formed by rain. It is said the water from rain seeps into the rock the rock via crevasses and once it evaporates, the silica that is left behind dries and hardens forming a precious opal, as an opal, is a hydrated amorphous form of silica, classified as a mineraloid; the light is diffracted due t the internal structure, giving it its distinctive appearance. 90% of the worlds opals, come from Australia.
There is much more attached to the opal, over the centuries, different cultures attaching and crediting supernatural origins and powers. The Greeks were believers that the stone offered protection from diseases and it bestowed upon its owner, the gift of prophesy.
Ancient Romans held the opal in high regard. Pliny the Elder, commander of the early Roman Empire said of this gemstone “Having a refulgent fire of the carbuncle (ruby or garnet), the glorious purple of amethyst, the sea green of emerald, and all those colours glittering together mixed in an incredible way.”
