Ettringite, Hausmannite and Andradite
Wessels Mine, Hotazel, Kalahari manganese field, Northern Cape, South Africa RSA
The Pastel Yellow of the Ettringite reminds me of a ice-cold Lemonade.
These gorgeous Ettringite crystals have developed on a gleaming beige to slightly red Andradite crystal matrix.
To add more of a wow factor to this rare specimen you can find Highly Metallic, opaque, triangles of Hausmannite too!
-Paula
The Geological Approach:
- Sub-metallic, opaque, dark grey to black, tetragonal Hausmannite.
- Growth patterning on the Hausmannite crystal surface.
- Vitreous, opaque, light brown, isometric Andradite.
- Andradite crystals have developed on the Hausmannite and in small vugs of the specimen.
- Pearly, sub-opaque, light yellow Ettringite crystals have developed on the Andradite surface
