Description
This is a fine and absolutely clean Quartz crystal from the Gotthard Basis Tunnel of the NEAT construction site of Switzerland. The single crystal is excellent developed, razor sharp and partially coated with tiny Apophyllite crystals. Such stuff is exceeding hard to come by, due to the fact, that only a small number of this material came to the official market. A super-rare specimen from the collection of Joachim Hennrich.
