HYALITE OPAL FROM NAMIBIA – EXCEPTIONAL UV FLUORESCENCE
This beautiful hyalite opal specimen from the Erongo region in Namibia impresses with its extraordinary botryoidal structure and its fascinating, intense neon-green fluorescence under UV light.
Even in normal daylight, the specimen displays an interesting natural mineral structure. On the dark brown rock matrix are numerous small, glass-like lustrous hyalite sections as well as a particularly striking, larger botryoidal formation.
Under 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.
This creates a beautiful, high-contrast luminous pattern that makes this specimen a special collector's item.

WHAT MAKES HYALITE SPECIAL?
Hyalite is a particularly clear to translucent variety of opal and is also known as glass opal due to its glass-like appearance.
Unlike many other opals, hyalite typically does not display a classic play-of-color. Its particular appeal often lies in its transparency, its extraordinary botryoidal growth forms, and its potential fluorescence.
Some hyalites contain small amounts of uranium in their natural mineral structure. These can cause intense green fluorescence under UV light.
Fluorescence is a natural optical phenomenon and makes certain hyalite specimens particularly interesting for collectors of fluorescent minerals.
A FASCINATING UV MINERAL SPECIMEN
In this specimen, the fluorescence is particularly well-defined.
The large botryoidal hyalite formation glows intensely neon green. Additionally, numerous smaller mineral parts on the matrix also show striking fluorescence.
Due to the varied distribution of the hyalite aggregates, a fascinating, individual luminous pattern emerges under UV illumination.
The combination of the dark matrix, the extraordinary growth form, and the intense UV reaction gives this specimen its special character.
The product photos show the specimen both under normal lighting and under UV light.
A NATURAL UNIQUE PIECE
You will receive exactly the pictured hyalite specimen from Namibia
The 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.
Natural inclusions, rock residues, and irregularities are part of the original character of this mineral specimen.
Note: The neon-green fluorescence is visible under UV illumination and cannot be seen at this intensity in normal daylight. The effect may vary depending on the UV lamp used.
