Harvested decades ago from the now-closed claims of eastern Wyoming, this mounted youngite cluster blends brecciated jasper and chalcedony in delicate blush-tan tones. Under short-wave UV light the agate matrix ignites in vivid green, revealing the signature fluorescence that makes youngite prized among collectors. Measuring 10" W × 8" D × 7.5" H on a custom steel base, the piece shows natural vugs, botryoidal textures, and breccia seams—evidence of its volcanic genesis. With all mine sites long shuttered, premium youngite like this has become increasingly scarce, elevating the specimen from mineral curiosity to true investment décor.
