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 on Mimetite
Ahumada Mine, Los Lamentos
9.8 x 7 x 4 CM (cabinet)
A very fine, attractive Bipyrimidal Wulfenite from Los Lamentos. This famed mine is best known for the tabular habit Wulfenites, but rarely this pointed habit was found, often on a dark green druze of tiny Mimetite crystals. Similar but noticably different from bipyrimidal Wulfs from Mina Ojuella. This specimen is esthetic, large, very colorful and in fine condition. A choice older Mexican classic Wulfenite.
Wulfenite with Calcite
stock #Alec 2-016
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.
