Phantom Quartz Double Terminator – Schyn Gorge, Thusis, Viamala, Graubünden, Switzerland
 Double-terminated rock crystal with the characteristic chlorite phantom from the Schyn Gorge in the canton of Graubünden. The chlorite inclusions give this crystal an intense green color, which is particularly beautifully emphasized by the shiny, crystal-clear surface.
 Since working and generally searching for minerals in and around the Schyn Gorge has been banned, pieces of this type are rarely available to purchase.
