Mottramite pseudomorph after Wulfenite with Calcite -
$1200
Some of the most interesting pseudomorphs after Wulfenite
have come from Tsumeb. This piece is a gorgeous and
showy example of deep green colored Mottramite forming pseudomorphs
after tabular Wulfenite crystals. To top it off,
the entire reverse side of the specimen is coated by
sharp, little, gemmy Calcite rhombs. The specimen
is rather intricate and three-dimensional, and looks
good from several angles. Despite some damage,
this remains as a good example of this rarely seen phenomenon
in the mineral world.
Locality: Tsumeb mine, Tsumeb,
Otjikoto Region,
Namibia
Specimen Size: 9.5 x 8.3 x 5.3 cm.

Malachite pseudomorph after Azurite - $400
Large, velvety, chatoyant blades of green Malachite which have
completely replaced Azurite forming a “fan-like” orientation
of crystals. The specimen is good sized, and fairly priced
for such a good representation of this classic Tsumeb occurrence.
Locality: Tsumeb mine, Tsumeb,
Otjikoto Region, Namibia
Specimen Size: 10.6 x 8.3 x 5.5 cm.

Malachite pseudomorph after Azurite plus Azurite on Duftite
- $1500
A wonderful combination specimen featuring subdued green color
blocky pseudomorphic Malachite crystals after Azurite which
are associated with non-pseudomorphed blue Azurite crystals
on the reverse side all sitting atop a coating of dark yellowish-green
Duftite on matrix. Not your typical Malachite ps. Azurite
specimen to be sure.
Locality: Tsumeb mine, Tsumeb,
Otjikoto Region, Namibia

Largest Malachite pseudomorph: 2.3

Dolomite cast after Calcite - $100
(SOLD)
The
great variety of casts and pseudomorphs from Tsumeb never ceases
to amaze me. This is a relatively simple and not terribly
rare replacement, but because it’s a “white on white” replacement,
it was not very easy to photograph. The specimen is comprised
of very very light bluish-green color Dolomite crystals forming
casts after Calcite. The are hollow shells over the top
of the original crystals, almost like thin capes that gently
drape across each corresponding face. If you are a fan
of casts from Tsumeb, this is one for you.
Locality: Tsumeb mine, Tsumeb,

Dolomite pseudomorph after Wulfenite - $2000
This is easily one of my top few favorite specimens in the entire
update. I have not seen another large cabinet specimen
of this material in such great condition. A piece like
this is by no means a common occurrence from Tsumeb (or any
other locality), and as I’ve said before, I’m a big fan of the
various pseudomorphs and casts from this locality. This
significant and historic (former Swoboda collection !) specimen
is comprised of small, light beige color Dolomite rhombohedra
coating, partially replacing, or completely replacing red-orange
color, tabular Wulfenite crystals. As you can see from
the photos, there are still some Wulfenite crystals present
on the piece, but there are also plenty of hollow casts where
a Wulfenite crystal once existed and is now gone. The
piece is in great shape overall, plus it’s very dramatic and
showy. It is glued to the acrylic base that accompanies
the specimen, but I think it could be removed fairly easily
if one so desired. It is not the sturdiest specimen in
the world, so we might have to make special arrangements with
anyone interested in purchasing the piece, because shipping
could be tricky. Nonetheless, it remains an impressive
and very attractive display specimen of this hard to find occurrence.
Locality: Tsumeb mine, Tsumeb,
Otjikoto Region, Namibia
Specimen Size: 16.0 x 11.8 x 5.5 cm.
Largest Pseudomorph: 3.8 cm.

Quartz cast after (?) - $300
An attractive very light green color cast of Quartz crystals
after an unknown mineral (perhaps Calcite?). It appears that
the light green color is caused by a micro inclusion of Malachite.

Malachite pseudomorphs after Azurites with Cerussite and Arsentsumebite
- $450
A great association specimen from noted rare species collector,
Bill Pinch. This specimen features one, predominant, euhedral,
complete, sharp, blocky pseudomorph of Malachite after Azurite
protruding from a matrix consisting of additional Malachite
pseudomorphs after Azurite plus white/colorless, gemmy, sharp
crystals of Cerussite. The final touch to this beauty is some
small spherical aggregates of apple-green color Arsentsumebite
scattered here and there. You don’t see many pieces like this,
especially with the highly coveted Arsentsumebite association.
Locality: Tsumeb mine, Tsumeb, Otjikoto Region, Namibia
Specimen Size: 6.5 x 5.5 x 5.1 cm.
Largest Pseudomorph: 2.2 cm.

Quartz casts/epimorphs after Wulfenite with Duftite -
$250 (SOLD)
What a gorgeous cast/epimorph specimen. I am a big fan of pseudomorphs
and casts from worldwide localities, and this one is certainly
one of the more interesting and attractive specimens of said
material that I have seen from Tsumeb. It features several casts
of sugary, colorless Quartz crystals after Wulfenite. You can
see in a few of the broken casts that they are completely hollow
inside, so these are not pseudomorphs, but casts (sometimes
called epimorphs or perimorphs). To top it off, the casts are
sitting on wonderfully contrasting green Duftite on matrix.
You gotta love the diversity of Tsumeb minerals.
Locality: Tsumeb mine, Tsumeb, Otjikoto Region, Namibia
Specimen Size: 6.8 x 4.6 x 2.5 cm.
Largest Quartz Cast: 6.0 mm.

Mottramite casts after Calcite - $225
Another very attractive cast or epimorph specimen of dark forest
green color, botryoidal Mottramite after rhombic Calcite. You
can see some of the broken casts are completely hollow inside
where the Calcite has totally dissolved away.
Locality: Tsumeb mine, Tsumeb, Otjikoto Region, Namibia
