The name opal was probably derived from Sanskrit “upala”, meaning “valuable stone” or from the Greek word “opallus” which means to see a change in color. Later, the Latin word “opalus” evolved, meaning precious stone. In the days of Roman antiquity there existed a so-called “opalus”, or a “stone from several elements”. Pliny the Elder, the famous Roman author, called opal a gemstone which combines the best possible characteristics of the most beautiful of gemstones; the fine sparkle of almandine, the shining purple of amethyst, the golden yellow of topaz, and the deep blue of sapphire, “so that all colors shine and sparkle together in a beautiful combination”. According to an old Australian Aboriginal legend, the Creator came down from the heavens on a rainbow and delivered a message of peace for all mankind. Stones that were near the place where His feet touched the ground suddenly came to life and began to sparkle. This was believed to be the birth of opal.
