Cupid Paederos – The Opal

Opal is the national gemstone of Australia and the birthstone for the month of October. The most striking feature of opal is the ability to refract and reflect specific wavelengths of colors. In fact, the term “opalescence” was coined to describe this phenomenon. The size and spacing of spheres of silica within the stone refract specific wavelengths of light; each sphere refracting a single, pure spectral color much like the droplets of water in a rainbow. The interplay of these pure wavelengths of light gives opal a unique visual.

Most opal is more than 65 million to 145 million years old. It is found in the Cretaceous layer of rock, formed when dinosaurs roamed the earth. Opal tends to be found near the earth’s surface in areas where ancient geothermal hot springs once flowed. The minerals bubbled up from beneath the surface of the earth and slowly over centuries lined the walls of cavities in the bedrock.

Opal is derived from the Latin word Upala that relates to precious stones and was considered the “cupid paederos” or child as beautiful as love. For Roman scholars, the opal represented hope and purity, a concept later adopted by modern Asian countries who consider the opal as a symbol of hope. The opal that the Romans referred was crystal formed volcanic gemstones in the Carpathian Mountains.  It featured flashes color that was not seen anywhere else in the ancient world and really impressed the Romans. Ancient Greeks believed opal had the power to have sixth sense in foresight and also prosperity.
