Lengenbach Quarry, Fald (Imfeld; Im Feld; Feld), Binn Valley, Wallis (Valais), Switzerland
Small Cabinet, 5.6 x 4.8 x 4.3 cm
Lengenbach is a very famous, important locality for many rare species, and yet perhaps the most normal species is sphalerite and they are equally treasured amongst the far more rare species here. The best of the sphalerites are absolute jewels, like this one: totally gemmy and with a bright amber color when lit up. This crystal is 5mm, sharp, and protected in a slight cavity in marble matrix. From the Museum of Bern, with catalogue label on the back.
