Description
This is a classic but rare species for the Alpes of Switzerland. A pseudomorph of Limonite after Pyrite from the locality Val Medel high up in the mountains in canton Grisons near the border to the canton Ticino. The specimen has a great resinous luster, sharp edges and only minimal imperfections. The striations on the crystal faces clearly point to the predecessor mineral Pyrite. The specimen comes with an old label. Material such as this is hardly offered on the market.
