What is the birthstone for October?

Opal occurs in a variety of colors and makes unique and beautiful jewelry. The play-of-color associated with opals is attributed to tiny spheres of crystobalite layered in siliceous Jelly. Opal always contain water, which also aides the opalescence of the stone. Some popular opal colors include black opal and white opals with white or other light body colors, which demonstrate play-of-color and internal fire.
