This is a preview site of my auctions run at e-rocks (seller name JN Minerals), when there are active auctions you will find the links below.
Specimen that were not sold during past auctions are also listed - please make an offer if you are interested in any of them.
16-118 - Rock Crystal - auction closing Dec 16
Size: 18 × 8.8 × 7.5 cm
Massive rock crystal from a famous find in the dangerous north face of Eiskögele mountain, made by the Hofer brothers in summer 2003 (cf. the video documentary available on DVD from the finder). Despite a good number of huge crystals in this find, only very few were recovered without damaged crystal tips - the specimen on hand has a repair at the bottom but comes with a pristine tip! A typical feature of the crystals from this find is one dominant, elongated rhombohedral face, which is displayed distinctly by the present specimen. The prism faces show highly lustrous sections alternating with interesting etching pattern. The backside carries some siderite crust with minor calcite and few speckles of ingrown chlorite. Seldom opportunity to get a decent specimen from this spectacular alpine crystal find!
