HYALITE OPAL FROM NAMIBIA – EXCEPTIONAL UV FLUORESCENCE
This beautiful hyalite opal specimen from the Erongo region of Namibia impresses with its extraordinary structure and its fascinating, intense neon-green fluorescence under UV light.
Even in normal daylight, the specimen displays an interesting natural mineral structure.
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 glowing pattern, making this specimen a special collector's item.

WHAT MAKES HYALITE SPECIAL?
Hyalite is a particularly clear to translucent variety of opal, and due to its glass-like appearance, it is also referred to as glass opal.
Unlike many other opals, hyalite does not normally exhibit a classic play-of-color. Its particular appeal often lies in its transparency, its extraordinary botryoidal growth forms, and its potential for fluorescence.
Some hyalites contain small amounts of uranium in their natural mineral structure. These can cause an 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 an intense neon green. In addition, numerous smaller mineral areas on the matrix also show striking fluorescence.
The varied distribution of the hyalite aggregates creates a fascinating, individual glowing pattern 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 under both normal lighting and UV light.
A NATURAL ONE-OF-A-KIND PIECE
You will receive exactly the hyalite specimen from Namibia shown
The 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.
Natural inclusions, rock remnants, 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 with this intensity in normal daylight. The effect may vary depending on the UV lamp used.
