A flat matrix is completely covered by small aragonite crystals which are rendered lemon yellow by abundant haiweeite inclusions. A previous dealer label identifies the major mineral as gypsum (common at the locality) but on this specimen the material produces vigorous effervescence with dilute hydrochloric acid (hence it cannot be gypsum). The same label identifies the yellow inclusions as nováčekite (a micaceous mineral) whereas examination of the specimen under magnification reveals this material to be acicular and therefore more likely to be haiweeite (but other yellow uranium species may also be present). The specimen is mildly radioactive and glows neon green under both longwave UV (blacklight) and shortwave UV. Overall condition is very nice.
