| Franklin Mineral Museum: Mineral crystals species |
A Sterling Hill classic. Here we have a crude but quite recognizable stubby willemite crystal. The color of the willemite is a pale yellow to a pale tan-orange. The willemite has a semi-vitreous to vitreous luster. There are a several large sections and grains of black metallic franklinite in and through the willemite. There are some minor coarse, white, opaque calcite in the matrix. Willemite was named after King Willem of the Netherlands from the localit...y at the Moresnet (Plombières-Altenberg-Moresnet) mining district, Verviers, Liège Province, Belgium. This species was previously discovered in 1825 and was identified as "siliceous oxyde of zinc" by Lardner Vanuxem and William Hypolitus Keating. At the time, "siliceous oxyde of zinc" was a synonym of electric calamine, now known as hemimorphite. The willemite fluoresces a bright green under shortwave (254nm) ultraviolet light. The specimen requires a prop in order to secure it for optimal display. This specimen is a nice example of this variety and it would make a fine addition to any collection assembling a suite of willemite from the Franklin and Sterling Hill zinc mining district.Dimensions are 3.5x6.2x3.5cm - 1¼x2¼x1¼in. Please note the centimeter cube and inch bar for scale.From the Sterling Mine, Ogdensburg, NJ.The previous collection this specimen was in is #123, the Princeton University Collection with an attached tag that reads #133. The tags were attached at Princeton University.#123 is the museum's Collection Sale number previously offered in the museum shop.>>> We do COMBINED SHIPPING for multiple items.

Most of the minerals from the Franklin and Sterling Hill zinc mining district fluoresce under shortwave ultraviolet light. The shortwave wavelength is 254nm or otherwise known as UV C. Always read the description carefully to determine if the main mineral of interest for a particular specimen will fluoresce. There are several available brands and models of ultraviolet lights on eBay and other online sources. For further information on ultraviolet light and fluorescent mineral go to Geology.com and then look under >> Minerals >> Fluorescent Minerals.>>>> We Buy Collections <<<<DISCLAIMER: Every reasonable effort was made to accurately identify the mineral specie(s) noted in each specimen. The occasional label from previous collection(s) may misidentify some species and the current title and description here reflects the latest mineral specie(s) identification. A modest effort was made to depict a fluorescent specimen accurately as possible, but some overexposure should be expected in some photographs to compensate for a weak response of a fluorescent specimen.--- All photographs appearing on this listing or any other Franklin Mineral Museum listing are the property of the Franklin Mineral Museum.
