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!

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.
A good, clean, classic Tsumeb Smithsonite that has fine esthetics. The crystals are fully translucent and have a slight zoning as well. These also have the iridescence inside the prisms that is distinctive for fine Tsumeb Smithsonite. In excellent condition damage-wise, this is a very good value for such a well formed cabinet specimen.
A very fine Tsumeb specimen with excellent zoned Smithsonite crystals on a contrasting matrix. This flat matrix displays well on both sides, it can be difficult to decide which is the better face to present. The "rear" has a huge stepped, etched Smithsonite crystal that is 2.4 CM across, the front shows several smaller, textbook perfect color-zoned crystals. Very esthetic and in fine condition.

Post Tucson 2015
Small but perfect and pretty miniature of crystallized Smithsonite in "rice grain" habit crystals covering the botroidal surfaces. A dusting of tiny Selenite crystals adds some contrast. Remarkably there is not the slightest hint of damage or bruising on this piece. Very nice color, structure and lustre.
