A cute miniature of Orange Wulfenites on a snowy white matrix of both Calcite and Gypsum. The Wulfenites have the bright wet look luster that is well-known from this locality. In excellent condition, this piece is from the most productive period, over 40 years ago.
Anglesite in Sulphur
Ahumada Mine, Los Lamentos
5.6 x 3.2 x 2.2 CM (small cabinet/ large miniature)
An oddity, from Los Lamentos, the locality world famed for superb Wulfenites, this is a different association. The mine contained a large amount of Sulfate minerals along with the Lead secondary species and some Native Sulphur. This Sulphur mass has both massive and micro crystal areas and is the matrix enclosing several Anglesite crystals about 1 CM in size. Not often seen for sale, this piece dates from the 1970's.
For the Ahumada Mine (Los Lamentos) this is a huge crystal of Anglesite for that mine, and is partly altered to Cerussite on the surface. Ex Johansson collection, this is an older piece, pre 1940. In very good condition and well-terminated as seen, (crudely doubly terminated) the crystal has retained the textbook form of the Anglesite. Los Lamentos is world famed for fine Wulfenite, Vanadinite and Descloisite but other Lead secondaries have been found over the long history of the mine. Large crystals of Anglesite are usually up to 2 CM, but at 4.3 CM this is one of the largest I have ever seen. A choice and substantial Mexican classic.
Dozens of lustrous wet-look Wulfenites are clustered in recesses on a complex matrix. Several of the Wulfenites are transparent on close exam, and they contrast well with the Calcite, Dolomite and a few colorless Quartz crystals. Most of the specimen is in fine condition but close (10x magnification) finds some small areas of chipping. By eye a strong display piece with good contrast and color. Ex Immer Cook collection, this was obtained from Schortmanns Minerals more than 40 years ago.
A sparkling coating of Descloizite on tabular habit Wulfenites that make up a large part of the matrix here. Very distinctive form and well exposed crystals make this a unique and remarkable specimen. In fine condition overall, this is from the 1960 era, and clearly not like most Los Lamentos pieces. The coating is on all sides except at the small point of attachment at the "bottom", in a few zones some of the orange color of the Wulfenites can be seen.
Wulfenite with Calcite
Ahumada Mine, Los Lamentos
8.4 x 6.9 CM (cabinet)
A fine and showy classic Los Lamentos specimen of lustrous butterscotch to orange wulfenite scattered on contrasting sparkling calcite. The Wulfenites are very sharp and glassy, reach 1.5 CM plus and are in some cases selectivly coated on the edges with a rind of calcite crystals. From an older collection, this is a less common style of Wulfenite for Los Lamentos, probably from the deepest zones. The major crystals are perfect damage wise, but some edge zones have minor damage showing. Despite this, for such a delicate, older specimen this is in exceptional condition and displays well.
