Austrian Alps: Minerals from alpine clefts and ore deposits
18-012 - Fluorite - 400 €
Steinbruch (quarry) Mauterndorf, Twenger Au, Taurachertal, Lungau, Salzburg, Austria
Size: 5.3 x 4.3 x 4.1 cm
Rather rare material from a limited find in 2015, when an isolated fluorite vein was found in the gravel quarry of Mauterndorf. While there came a bunch of heavily etched fluorites on the market, the specimen on hand is one of the very few pieces with well preserved cubical faces and distinct color zoning. The fluorite shows green-turquoise to slight purple colors when lit with daylight or a 6500K-LED, and pink-reddish color tones under yellow illumination with a classic light bulb. Seldom opportunity to get a significant specimen of this find, no more material is expected to follow since the fluorite vein has been excavated in the meantime.

Wildenkogel, Venediger, Osttirol, Austria
Size: 7 × 3.2 × 3 cm
Skeletonized rock crystal with good luster and clarity. Some abrasion near the tip, though not very eye-catching on a highly structured piece like this. Found by the renowned Austrian collector Obkircher Gottlieb.

Rock Crystal & Calcite - sold
Kleiner Hexenkopf, Mailfrosnitz, Frosnitztal, Osttirol, Austria
Size: 22 x 16 x 10 cm
Massy group of rock crystals with turquoise schist inclusions accompanied by reddish-white, dull calcite scalenohedra on matrix. The rock crystals measure up to 3 cm in diameter. There are several contacts and ruptures from frost and tectonic activity - while that is for sure an impairment, it somehow also adds a wild, alpine character to this particular specimen.
16-066 - Quartz - 80 €
Grieswies-Schwarzkopf, Hüttwinkl Tal, Rauris, Salzburg, Austria
Size: 16 x 8 x 8 cm
Densely packed group of rock crystals, crystallized on all sides and partially developed doubly terminated. The bottom side carries some limonite and pericline. No significant damage.

Size: 4.5 x 3.2 x 1.8 cm
Floater piece from a renowned alpine fluorite cleft worked by Rudolf Hasler in 1998 and 2013 (cf. Lapis 03/2014). Nicely balanced specimen in paragenesis with mostly clear and lustrous rock crystals. The fluorite octahedra measure up to 11 mm on edge. The second fluorite generation grown in rhombic dodecahedral habit with ink-blue color accents is the unique feature of this particular find. The specimen is in excellent condition, free of significant damage.
Fluorite & Rock Crystal - sold
Schwarze Wand, Tauerntal, Mallnitz, Carinthia, Austria
Size: 5.5 x 4 x 3.5 cm
Floater piece from a renowned alpine fluorite cleft worked by Rudolf Hasler in 1998 and 2013 (cf. Lapis 03/2014). Nicely balanced specimen in paragenesis with mostly clear and lustrous rock crystals. The main fluorite octahedron measures 15 mm on edge. The octahedron at the bottom also carries the ink-blue second fluorite generation, which the Bockriegel specimen are famous for. The specimen is in excellent condition, there are some rehealed ruptures among the quartz needles but hardly any fresh fracture surface.
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!
Fluorite & Quartz - sold
Stampflkees, Zamser Grund, Zillertal, Tirol, Austria
Size: 10.8 x 7.2 x 5.1 cm
Purple fluorite octahedra partially encrusted with a yellowish quartz layer. The specimen stems from a famous find in the 1980's from the slopes below the Stampflkees. While most of the fluorites from this find were green, the purple color of the specimen on hand is rather rare and very much sought-after among collectors.
Three twinned titanite crystals up to 12 mm length on matrix. The titanites exhibit the typical colour of the Kristallwand find, i.e. cognac-like with some green and red accents. In addition to the three main crystals, there are several tiny titanites and mica crystals scattered over the display side of the specimen. No significant damage.
Rock Crystal Scepter - sold
