A very specialized US gem certainly - a special cabochon cut from an intergrowth of classic Willemite (the light yellowish-green) and Leucophoenite, a mineral first categorized at Franklin. In addition to the rather attractive color combination, the Willemite is highly fluorescent under longwave UV - an added bonus. There are not many of these and this one is quite large as these go.
