Cerussite and Dundasite
Modra Stola, Ziate Hory, Olomouc Region
6.9 x 6.4 x 4.1 CM (cabinet)
A rich specimen of accicular Cerussite that is covered with tiny needles and micro balls of greenish to white Dundasite. The whole piece has a pleasing minty green hue due mostly to the Dundasite. Dundasite is a rather rare mineral and usually seen as an associate of Cerussite. This locality is an ancient abandoned mine dating to the fifteenth century which produced some good lead secondary minerals from the oxidized zone to modern (1980 vintage) collectors. Close exam of the Cerussite shows that the individual needles are sixling twins with a star-like cross section. Choice and very fine for the locale.
Dundasite with Allophane
Juanite Mine, Magdalena
5.8 x 4.2 x 4.4 CM (small cabinet/ large miniature)
Worldwide mix summer
A vuggy matrix hosts balls of crystalized Dundasite (white acicular needles in spheres) and bright blue and green Allophane. From the Juanita mine, in the famed Magdalena district of New Mexico, this is a moderately rich specimen that has several zones with tiny Dundasite balls. We do not see this material very often, this older piece was in the Hladysz collection.
