Opal Earrings with French Back
Beautiful, flashy and bright Australian opals set in sterling silver. These lightweight and colorful earrings are the perfect day into night time earring, lightweight, sparkling and comfortable. These are Australian opal doublets which are comprised of an opal layer backed with an ironstone layer for strength and thickness.
Australian Opals are formed when water runs down through the earth and mixes with silicon dioxide. As the water seeps into cracks and crevices (that are caused by natural faults or decomposing fossils), the water eventually evaporates, leaving the silica. The silica particles catch the light and diffract it, giving the stones the luminescent quality opals are known for.
