6.7" Druzy Smithsonite Crystal Aggregation - Tsumeb Mine, Namibia

This is a beautiful, 6.7" wide formation of smithsonite with multiple generations of crystal growth. It was collected from the Tsumeb Mine in Namibia, a locale known for its various smithsonite crystal forms and colors. The underlying generations formed with a rounded/druzy habit and exhibit a silky luster, with larger crystals scattered across the specimen. One edge of the specimen features sharp crystals with lustrous faces.

It comes with an acrylic display stand.

Smithsonite is known to form in earthy botryoidal masses, sometimes forming grape-like structures. It can be found as a secondary mineral in oxidation zones of zinc ore deposits, in some sedimentary deposits and as an oxidation product of sphalerite. The general chemical formula of smithsonite is ZnCO3, however Fe (iron), Mg (magnesium), Ca (calcium), Cd (cadmium), Cu (copper), and Co (cobalt) can take the place of Zn (zinc). This potential for elemental variation results in smithsonite having the ability to exhibit a wide variety of colors including blue, green, yellow, orange, pink, purple, brown, gray, white and colorless.
