- Bayldonite Ps. Mimetite
- Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
- Miniature, 3.8 x 3.6 x 2.7 cm
A REMARKABLE, aesthetic and old-time Tsumeb pseudomorph featuring a splaying cluster of green bayldonite after very long, thin mimetite crystals. The pseudos reach about an inch. Classic, upper level material from Tsumeb's early years prior to WWI: These are thought to have been mined prior to the 1920s. Aesthetic examples are today very RARE AND HARD TO OBTAIN, but in any case are also attractive pseudos aside from the historical value! This is a competition-worthy miniature. Interestingly, I am told that many of these when analyzed turn out to be the much rarer species, ARSENTSUMEBITE, which would be a bonus. I have not tested this one, and most specimens carry the Bayldonite label as historically they have done, but due to the dark color here, I rate the chance highly this is, indeed, arsentsumebite.
