Rosasite pseudomorph after
Malachite pseudomorph after Azurite - $600 Reduced
to $540 Tsumeb, Otjikoto Region, Namibia 10.8 x 8.4 x 8.4 cm (4.3 x 3.3 x 3.3 inches) Specimen status: Available Click here to order This is an exceptionally large
example from a locality famous for malachite after azurite
pseudomorphs. The terminations are incomplete, but this is minor
considering the size of this specimen: the longest single crystal is an
impressive 9.8 cm. Several display angles possible without a stand.
Price would have another zero (at least) if the terminations were
complete.

translucent to opaque
vanadinite crystals on a crystalline goethite matrix. The vanadinites
reach 6 mm in length and have a nifty resinous luster. The gray matrix
is composed of gossan plus sparkly,
submillimeter, rectangular goethite crystals. A few small vanadinite
chips are noted. Could probably be trimmed to emphasize the best
vanadinites at the top of the first photo.

Kernite - $18 Reduced
to $16 Boron, Kramer District, Kern County, California 12.6 x 2.9 x 1.8 cm (5.0 x 1.1 x 0.7 inches) Specimen status: Available Click here to order A mostly-transparent, colorless kernite
crystal shard. (Complete kernite crystals are rare.) The Boron area
mines are all but closed to collecting, so kernite specimens
(especially
of this size) are only rarely available outside of
southern California. Very typical for the species and locality.

Rhodochrosite and Quartz - $175 Reduced
to $99 Sweet Home Mine, Alma District, Park County, Colorado 13.5 x 10.8 x 6.0 cm (5.3 x 4.3 x 2.4 inches) Specimen status: Available Click here to order About a dozen pink to red rhodochrosite crystals on and in a matrix of quartz crust and needles. The rhodochrosites are opaque to translucent, reach 1.3 cm across, with mostly natural crystal faces. More crystals might be revealed by careful removal of more quartz. Minor fluorite also present. Sawn edges and back (as commonly necessary for specimen extraction when the matrix is tough), but this do not detract. |

Mimetite, Wulfenite, and Calcite - $18 Reduced

tiny and fuzzy but sparkly yellow mimetite crystals. (The vug's depth
makes it hard to photograph.) Also present are a few translucent to
opaque, colorless calcite rhombs (these reach 1 cm) and opaque,
somewhat ragged wulfenite blades.

calcite crystals on a hollow basalt matrix. Reminiscent to me of a
baked potato. The calcites are translucent to transparent, with a
glassy luster. Both reach 4.7 cm along the edge. Despite the tool marks
around the exterior, an aesthetic specimen. Displays nicely; the two
edge cleaves do not detract.
