Unusual specimen of transparent botryoidal chalcedony var. hyalite on matrix, with unique daylight (daylight, LED and neon light) fluorescence in intense green color. This piece have the strongest daylight fluorescence possible from the find! In artificial light (incandescent) hyalite became amost colorless, and in UV light it is crazy neon-green. Fluorescence is caused by small uranium content. Cutting quality material. This type of hyalites are known from this only locality in the world. Great 3D form and luster! Spectacular!
