3.7" Rich MossyGreen MOTTRAMITE Bubbly Botryoidal Fuzzy Crystals Mexico for sale
Availability: In Stock
Here is a superb specimen of velvety mottramite on brown gossan matrix from the new, late 2011 find at the Ojuela Mine in Mapimi. The mineral is formed in a botryoidal habit (it's actually microcrystalline), and the color is a dark, forest green. Because of its richness and the fully developed botryoidal forms, the quality is very high. Specimens from this find were positively identified as near-end member mottramite by the folks at the University of Arizona, who used X-ray diffraction and unit cell refinement. Specimens of mottramite of this quality haven't been available since the heyday years at Tsumeb.
