well, the TRADITIONAL list of precious stones actually does include opal, but it also includes Pearl and Amethyst. (So why dont we have them as precious stones in their trivia to?)

(though amethyst was re-classified as a Semi-Precious 'after large deposits were found in Brazil and Uruguay in the first half of the ninteenth century. but from my knowledge pearl is also considered precious, or were.')''
