Binn valley: Cleft minerals from the Alps most diverse valley

The Swiss Binn valley is world-renowned for its unrivaled variety of minerals, ranging from high-class specimen of all typical alpine cleft minerals to rare sulfosalt and Thallium compounds. The Binn valley is a secondary valley of the Rhone valley in the Swiss Kanton Wallis, and it is characterized by a very complex folding of geological series. The northern parts of the valley are dominated by Bündner schist and comprise the locales Turben area and Feldbach, famous for beautiful rock crystals grown in transitional/Tessin habitus and the signature variant "Binntal habitus". The Lengenbach quarry, type locality for more than 30 minerals, is situated in a dolomite formation hosting Arsenic ore mineralisations. The southern parts of the valley cut through various gneiss formations including the Lärcheltini area, renowned for anatase crystals in a unique variety of shapes and colours, as well as magnetite, rutile and hematite iron roses.

The specimen from the Lärcheltini area I am lucky to offer below are all from finds made in the 1990's - nowadays this locale becomes increasingly inaccessible because climate change yields a pronounced elevation of the vegetation limit, so that the formerly bare rock surface in this area is now covered with soil and vegetation.

Impressive combination of a multi-head scepter quartz towering above a 13.5 cm long, doubly terminated rock crystal. The scepter shows distinct windows and great luster. The specimen might be repaired, even though the finder told me it was not and I had it surviving one night in aceton.

16-155 - Magnetite & Rutile - 150 €

Kollergraben, Lärcheltini area, Binn valley, Wallis, Switzerland

Size: 7 x 3.5 x 2 cm

Complex rutile twin of 5 mm height and magnetite octahedron of 4 mm edge length on mica coated matrix. Both crystals show bright metallic luster and are free of significant damage.

PL-021 - Titanite - 300 €

Hillehorn, Binn valley, Wallis, Switzerland

Size: 4 x 3.5 x 3.5 cm

360° video and full resolution images

Cluster of intergrown titanite twins with a dominant front crystal of 4 cm length. The prevailing color is green, partially altered to brown-reddish and colorless zones. There is some chlorite scattered over the piece and the crystal edges are somewhat eroded/etched, but the entire specimen is free of significant damage. Appealing 360° sculpture which stands up to comparison with Austrian titanites.

PL-018 - Morion - 150 €

Blau lake, Saflisch Valley, Binn Valley, Wallis, Switzerland

Size: 6.5 x 5 x 3.5 cm

360° video and full resolution images

Gorgeous morion crystal from one of the very few Swiss localities for this rare quartz variant. The specimen features great luster on all faces and despite its near-black color a clear, transparent interior when backlit. Due to a growth inhibition or an contact during an early growth stage, the crystal top is split into multiple terminations forming a black, lustrous crown. The specimen is flawless all around with an old contact at the side being fully recrystallized.

PL-019 - Faden Quartz - 180 €

Turbhorn area, Binn valley, Wallis, Switzerland

Size: 8 x 7.5 x 7.5 cm

360° video and full resolution images

Unusual, dense aggregate of multiple parallel quartz faden. The locality Turbhorn area is clearly identifiable from many rock crystal individuals exhibiting the typical transitional habitus. The main faden lines branch into dozends of mini faden towards the bottom. No significant damage.

Chummibort, Binn valley, Wallis, Switzerland

Size: up to 54 mm (see image captions)

360° videos and full resolution images

Lot of doubly terminated, sceptered amethyst crystals on pale smoky quartz - all from the same cleft. The amethyst crystals on all specimen are free of significant damage, the smoky quartz crystals of specimen D-G exhibit some rather marginal damage, see the 360° videos.
