Phantom Fluorite – Bergmännisch Glück Mine, Frohnau, Erzgebirge, Saxony, Germany.
Beautiful sharp-colorzoned fluorite crystals up to 1.2 cm in size as an unique crystal cluster from the famous Bergmännisch Glueck Mine, Frohnau, Ore Mts., Saxony, Germany. Fotos were taken when backlit the piece. Slight power of light is a enough for illuminating this beauty.
Inside of the amber-yellow fluorite crystals there are sharp signed blue to purple colorzones visible. Very expressive coloration from a small find before the pieces with the blue phantoms were found. A few chalcopyrite crystals are also visible. The matieral is highly sought after among the locals and the fluorite collectors. Much better in person!
