On the dark brown rock matrix are numerous small, glass-like lustrous hyalite sections as well as a particularly striking, larger botryoidal formation.\u003cbr\u003e\u003cbr\u003eUnder UV light, the specimen reveals its full beauty: the large hyalite section glows in an intense neon green, while numerous other fluorescent areas are distributed across the entire matrix.\u003cbr\u003e\u003cbr\u003eThis creates a beautiful, high-contrast luminous pattern that makes this specimen a special collector's item.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eORIGIN \u0026amp; MINERALOGY\u003cbr\u003e\u003cbr\u003e• Mineral: Hyalite (Hyalite Opal)\u003cbr\u003e• Mineral group: Opal\u003cbr\u003e• Chemical composition: SiO₂ · nH₂O\u003cbr\u003e• Origin: Erongo Region, Namibia\u003cbr\u003e• Size: approx. 40 × 28 × 11 mm\u003cbr\u003e• Weight: 11.6 g\u003cbr\u003e• Color: Colorless to whitish on dark brown matrix\u003cbr\u003e• Fluorescence: Intense neon green under UV light\u003cbr\u003e• Habit: Botryoidal, glass-like lustrous mineral aggregates\u003cbr\u003e• Associated rock: Natural dark brown matrix, exact composition not determined\u003cbr\u003e• Processing: Natural mineral specimen\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eWHAT MAKES HYALITE SPECIAL?\u003cbr\u003e\u003cbr\u003eHyalite is a particularly clear to translucent variety of opal and is also referred to as glass opal due to its glass-like appearance.\u003cbr\u003e\u003cbr\u003eUnlike many other opals, hyalite generally does not show a classic play-of-color. Its particular appeal often lies in its transparency, its extraordinary botryoidal growth forms, and its potential 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\u003eThe fluorescence 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 intense neon green. Additionally, numerous smaller mineral sections on the matrix also show striking fluorescence.\u003cbr\u003e\u003cbr\u003eDue to the varying distribution of the hyalite aggregates, a fascinating, individual luminous pattern is created under UV lighting.\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 both in normal lighting and under UV light.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eA NATURAL UNIQUE PIECE\u003cbr\u003e\u003cbr\u003eYou will receive exactly the pictured hyalite specimen from Namibia \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 lovers of fluorescent minerals.\u003cbr\u003e\u003cbr\u003eNatural inclusions, rock residues, and irregularities are part of the original character of this mineral specimen.\u003cbr\u003e\u003cbr\u003eNote: The neon-green fluorescence becomes visible through UV lighting and cannot be seen at this intensity in normal daylight.
