Pre Holiday 2017
This specimen is one of a kind, a unique Tsumeb oddity with great esthetics. An elongated, gemmy crystal of Smithsonite rises from a gossan matrix and hosts a few gem clear smokey Cerussites. The Smithsonite shows signs of being a compound crystal with parallel growth but a single termination. The Cerussites and a tiny part of the Smithsonite (only seen with magnification) are chipped but this is on the "back" not visible on display, the front and side view are pristine undamaged. Tiny Calcites with some odd habits are also scattered on the matrix. The crazy composition of this specimen is typical of why so many collectors love Tsumeb minerals.
A fine and very unusual type of of Smithsonite specimen from Tsumeb. Ex John Schneider collection, this has light pink to violet transparent crystals of Smithsonite densely covering 3 parallel fingers or stalactites of Galena. In excellent condition with wonderful esthetics, this is a really weird but choice Tsumeb specimen.
From the noted collection of Wallace Gould Levison, purchased by him in 1893 from an even older collection obtained by HG Diserow, seemingly pre 1870. Classic translucent Smithsonite from Laurium with fine blue green color, sawn and lightly polished. A photocopy of Levisons handwritten catalog entry page for this specimen is supplied with the piece. Levison was an important Victorian era US collector, inventor (first patent for a movie camera, UV mineral systems etc.) and prolific author.
Smithsonite with Calcite
Kelly Mine, Magdalena
8.8 x 6.3 x 3 CM (cabinet)
A very pretty, classic Smithsonite from the famed Kelly mine. Nice wet look luster and three dimensional surface. In fine condition, undamaged on the display side, sawn on the back and sits well for display. These have become quite prized over the past few years and this is a particularly good value for this quality. The large knob that protrudes from the concave area is 3.2 CM across and has a few small Calcites on the surface.
Sharp crystals of Smithsonite cover a matrix of Cerussite with some twinned crystals showing. The Smithsonites are all perfect and undamaged. A nice association the milky white Smithsonite crystals have nice contrast to the grey Cerussite.
Yellow-hued crystals of transparent Smithsonite up to 2.5 CM long are sticking out in all directions on this complex yet esthetic piece. In outstanding condition overall, there is one crystal with a broken termination that will be hidden on most logical display angles. All of the other crystals are quite perfect. Without analysis I am not sure if this should be called Cadmian Smithsonite as many yellow examples are labelled. Choice and attractive.
Smithsonite on Galena
4 x 3.3 x 2.9 CM (miniature)
Outstanding esthetics, in fine condition a very choice Tsumeb piece. The matrix is the classic type of Tsumeb Galena with small areas of Cerussite best seen with magnification. The Smithsonites contrast nicely with the matrix. Colorless to very pale pink hues on crystals reaching 1.7 CM with fine transparency as well. Displays with great impact despite the small size!
5.4 x 3.8 x 3.3 CM (cabinet)
A well formed Tsumeb Smithsonite with individual crystals up to 1 CM. It has become common to refer to all Smithsonite that is yellow to orange as "Cadmian". However, without an analysis to confirm this may not be correct in all cases. This specimen has not been analyzed but it does have a very good color, form and will fit well into a Smithsonite or Tsumeb suite.
