Fluorite, Dörfel Quarry, Annaberg, Saxony, Germany
A very interesting fluorite specimen here: Yellow and quite transparent fluorite cubes up to 2.9 cm in size with partly up to 6 different phantom layers inside - which are visible especially in the main crystal atop of the piece.
These phantom layers are well-defined with strong coloration - alternating between deep blue and yellow. Awesome "phantom-fluorite" specimen from the famous Doerfel Quarry nearby Annaberg, Ore Mts., Saxony, Germany. Found in the year 2017.
