It is famously found in the Mineral Mountains near Milford, Utah, and is also known locally by names like bacon opal, candy opal, or satin flash opal. Formed of roughly 90% to 95% silicate opal with trace mineral impurities such as iron, copper, and magnesium. Many hyalite opals exhibit a strong bright green reaction under shortwave ultraviolet light due to trace amounts of uranium/uranyl ions.
