| Mineral: | Siderite on Quartz |
| Locality: | | Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro, Portugal |  |

| Dimensions: | 14.5 x 13.5 x 18 cm / main crystal: 8.1 cm |
| Description: |
Mass: 1500 g
MIM number: 1540
Probable year of extraction : 1979
Two intact, well formed cream-colored rhombohedrons with another smaller one at the junction of the two larger ones. These siderites are stuck at the base of two quartz crystals in a V-shape exhibiting black inclusions at their terminations (the largest quartz measuring 18 cm). The group is a floater: the lower portion of the quartz crystals is entirely recrystallized.

The söhngeite aggregates are made up of penetration twins, in which the individual crystals present with a characteristic perpendicular orientation. Two small, elongated, transparent crystals (probably stibioclaudetite?) are also on the gangue. This remarkable specimen was originally in the collection of Professor Hugo Strunz, who described söhngeite as a new mineral from Tsumeb (Strunz, 1965).

Mass: 3670 g
MIM number: 1487
Block of very lustrous, transparent, dark blue twinned cubic crystals, all with a milky-white face in the same direction. The crystals appear deep purple under incandescent light, probably due to fluorescence; white-cream baryte crystals stud the tops of a few fluorite crystals.
