A fine vintage specimen of crystallized Pharmacosiderite, a rather rare specie and a Cornish classic. The label on this specimen dates to pre 1870 when the Mines were absorbed and names changed. The crystals are as always best seen with magnification (or great eyesight!) they are very sharp and distinct, rich green, lustrous, glassy cubic and transparent to translucent. A very elegant small piece with a Frieburg collection label that adds a nice provenance.
A classic old Copper secondaries specimen with several old labels including a Wards label from 1913-22 vintage. Melanochalcite forms a thin zone around Cuprite in Nodules like this near Bisbee. This is an old varietal name for Tenorite which was first described in 1902. Other Copper secondaries are present as are several old handwritten labels in Italian. A colorful antique specimen.
Superb pseudomorph in a complete crystal, double terminated and far sharper than any other I have seen. Classic specimen with a Wards label dating this to over 100 years ago, (after 1913 shortly after George English began to work there). The label bears his handwriting. The Talc is the Steatite variety and more hard than other Talc so the condition of the replacement is nearly perfect. A fine piece for a Pseudomorph suite, and a great old classic on its own.
Elbaite - curved, rehealed crystal
Barra do Salinas Mining District, Coronel Murta
3.8 x 3. 2.8 CM (miniature)
An older, fat and substantial Elbaite crystal with a slight curve where it has rehealed. Multi color, 48 grams and with a white fibrous zone at the bend point. There is scattered bits of Clevelandite on a few faces. Good luster and quite sharp complex termination. Better in person too.
A clean textbook quality example of a gemmy Carthage corner Fluorite. The larger cube has typical frosted, stepped faces and translucent purple surfaces but the corner is glass smooth, perfectly colorless and gem clear, a window into the interior of the crystal. A modern classic habit from the Elmwood mine, this is much more impressive in person and an esthetic mineralogical curiosity.
Adamite- fan form crystals
Mina Ojuela, Mapimi
4.6 x 3.9 x 3 CM (miniature)
Delicate sprays of Adamite in the classic fan form that are nicely perched on mix of Gossan and other Adamites. Attractive small miniature in fine condition, with fans up to 1.8 CM. Good luster and distinctive form this can only be from Mina Ojuela. From 2013 finds, good fans have become hard to find.
Gold- Sheet crystal habit
Round Mountain, Open Pit Gold mine, Nye County
3.1 x 2.1 x .2 CM (thumbnail)
A pure sheet of Gold with some flattened crystal faces and structures evident. Thin but substantial, this has a bright luster and looks great on both sides. Mined in 2006, this weighs just 1.3 grams but due to the flat form it looks very impressive for the weight. The variety of fine Gold specimens that has come out of Round mountain is incredible. Choice.
Gold in Quartz
Henderson Mine, Chibougamou
3.8 x 3.7 x 2 CM (small miniature)
Gold in crystals, sheets and massive zones densely filling a veined Quartz matrix. From the Henderson mine in Chibougamou, this is an especially rich specimen from the locale that is famed for the worlds best Cubanites. Very few specimens of Gold have been preserved from this locality, Ex Glenn Petrie, and Les Hitchings collections. The Gold is visible on every surface of the matrix, and under magnification the richness and complex delicate structures are very elegant. Total weight of 34 grams I would guess the bulk of that weight is Gold.
