Precious Opals
Precious Opals (SiO₂ nH₂O) are among the most valuable opal varieties, renowned for their extraordinary play of color, including every shade of the rainbow. They form through the deposition of amorphous silica in sedimentary or volcanic environments. Noble opals include specimens from Ethiopia, Australia, Mexico, and Brazil. Each stone is a natural work of art, celebrated for its ethereal beauty and vibrant energy.
