Opal's Twin Delight: Australian Opal Doublet Dazzling Duo
Opals are gemstones that originate from a combination of silicon dioxide and water. Over time, water seeps into the depths of the Earth, where it merges with silica derived from sandstone. This water then infiltrates cracks and crevices within rocks. Upon evaporating, it leaves behind silica deposits. This process recurs, leading to the formation of opals. Australian Doublet Opals are so named because of their origin from Australia.
