Its particular appeal often lies in its transparency, its extraordinary botryoidal growth forms, and its potential for fluorescence.\u003cbr\u003e\u003cbr\u003eSome hyalites contain small amounts of uranium in their natural mineral structure. These can cause an intense green fluorescence under UV light.\u003cbr\u003e\u003cbr\u003eFluorescence is a natural optical phenomenon and makes certain hyalite specimens particularly interesting for collectors of fluorescent minerals.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eA FASCINATING UV MINERAL SPECIMEN\u003cbr\u003e\u003cbr\u003eIn this specimen, the fluorescence is particularly well-defined.\u003cbr\u003e\u003cbr\u003eThe large botryoidal hyalite formation glows an intense neon green. In addition, numerous smaller mineral areas on the matrix also show striking fluorescence.\u003cbr\u003e\u003cbr\u003eThe varied distribution of the hyalite aggregates creates a fascinating, individual glowing pattern under UV illumination.\u003cbr\u003e\u003cbr\u003eThe combination of the dark matrix, the extraordinary growth form, and the intense UV reaction gives this specimen its special character.\u003cbr\u003e\u003cbr\u003eThe product photos show the specimen under both normal lighting and UV light.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eA NATURAL ONE-OF-A-KIND PIECE\u003cbr\u003e\u003cbr\u003eYou will receive exactly the hyalite specimen from Namibia shown\u003cbr\u003e\u003cbr\u003eThe extraordinary botryoidal structure and the intense neon-green fluorescence pattern make this specimen a special, unique piece for mineral collectors and enthusiasts of fluorescent minerals.\u003cbr\u003e\u003cbr\u003eNatural inclusions, rock remnants, and irregularities are part of the original character of this mineral specimen.\u003cbr\u003e\u003cbr\u003eNote: The neon-green fluorescence is visible under UV illumination and cannot be seen with this intensity in normal daylight.
