This rare mineral specimen from Erongo, Namibia, is distinguished by its bright yellow hyalite opal crystals, which fluoresce neon yellow under UV light. The hyalite crystals grow on a white-beige orthoclase, accompanied by black schorl tourmaline and muscovite.
With compact dimensions of 49 x 32 x 30 mm and a weight of 50 g, this specimen is an exceptional collector's item with intense UV luminosity. The combination of various minerals and the rare fluorescent hyalite variety make it particularly valuable.
