Unusual specimen of transparent botryoidal chalcedony var. hyalite on matrix, with unique fluorescence in intense green color. In artificial light (incandescent) hyalite became yellow/green 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. Good 3D form and luster! From exhausted locality!
