Mineral Specimens with Lengenbachite
- 1 specimen selected
8.5 x 8.4 x 7.0 cm. Lengenbachite is one of the rarest of the macrocrystalline oddities from this amazing locality. Binnite is the multi-faceted, rounded variety of tennantite, as it was known from the famed Lengenbach deposit of Switzerland. This is a most unusual tennantite specimen, in that the 1.0 cm binnite crystal is coated with nubby, iridescent marcasite, giving it a sheen. Two Lengenbachite plates at the base of this strange looking crystal are a nice compliment and they species really accent each other. For freestanding Lengenbachite, these are pretty good, actually - and nicely protected in the crevasse, as well. The binnite and Lengenbachite cluster is adroitly set in a cleft atop a block of sugary, banded dolomite. The marcasite on the tennantite makes for a rarely encountered and most interesting looking Lengenbach combination specimen. Ex. University of Bern and Rolf Wein Collections.
