Opal is a brilliant gemstone that develops in silica-rich water. Amplification, purification, and hope are all represented by the opal. The Sanskrit term upala, which means precious stone, is whence the word opal was originated. Some individuals also thought the word "opal" came from the Latin word "opalus," while others thought it originated from the Greek word "opallios." Opal was known as opallios in Roman times.
