Classic old Pitcher Field (Tri State District) Galena. An esthetic cluster of grey patina cubes with modified corners on a drusy Sphalerite covering the Chert matrix. In excellent condition, the Galena arrangement is very three dimensional and the cube at the top on the tower is 2 CM in diameter. The backside of the matrix is covered with larger Sphalerites some of which are red and lustrous. The Tri state area was an incredibly productive zone into the early 1960 period when it shut down. At the time these specimens were plentiful (although better pieces were always much less common). Today these are all long gone and good esthetic material is quite rare. Far better in person, this is not at all average.
A lustrous cluster of mostly Pyargyrite crystals that at first glance appear a silvery black color. Strong light shows some brilliant red zones of ruby silver, and with magnification are some classic twinned Polybasite crystals as well. Minimal matrix, the associated Sulphides are only seen with magnification. Some edge chipping is noted, not easy to see by naked eye (this is a brittle mineral ) but the main crystals are in fine condition, some with textbook forms. The Pyrargyrites have some unusual habits on this piece, it is an attractive small miniature with very bright flash., could trim to a very strong thumbnail if desired
Linopolis, Divino das Laranjeiras, Doce Valley
7.8 x 5.3 x 3.7 CM (cabinet)
A sculptural tower of Brazilianite crystals most of which are doubly terminated. An early 1970 vintage specimen with no matrix at all just several generations of Brazilianite in several habits nicely composed as a zigzag arrangement. In excellent condition, all the main crystals are undamaged, with 20X magnification, only a tiny chips are found in spots that are not seen on display, perfect by naked eye. The smaller crystals are transparent, gemmy and very lustrous, the larger ones have inclusions that are seen just inside the faces and give a more matte look but still have glassy faces outside. Not typical, the esthetics are fine and far better in person.
Copper -spinel twinned
Emke Mine, Onganja, Seiis
3.9 x 1.2 x .4 CM (miniature)
A spire of interlocked spinel twin Copper crystals with side branches and sharp terminations. From the now classic, closed Emke mine at Oganja, this is the style and habit that are distinctive for this locale. No damage, nice patina and especially nice under magnification. Larger examples from this locale are highly desired and now very expensive. This is a choice smaller piece that is perfect and affordable. .
An "air clear" colorless Topaz crystal with perfect form from the famed Mogok gem region of Myanmar. The termination has additional face modifications and the condition is perfect, undamaged and with no internal cleaves. The Topaz of the Sakangyi can sometimes have an exceptional level of optical clarity, but most have some clouds or cleaves. Competition grade miniature that is especially impressive in person. So clear and glasslike it is difficult to photograph.
An attractive combination specimen from the remarkable finds at the Christmas mine. This is the type locale for Ruizite and one of the best locales for Kinoite. There are several vugs that are hold very tiny Ruizite in reddish balls. and much larger bright blue Kinoite mostly of covered by clear Apophyllite crystals. By eye it also looks like there is a few areas of Apacheite (powder blue) but this is not confirmed.
3.1 x 2.7 x 2.4 CM (small miniature/ large thumbnail (toenail))
A choice early Azurite from Tsumeb formerly in the Johannson collection obtained in trade with Harvard before 1933. Thick rectangular blades in a mass on minimal matrix. Excellent luster and a somewhat unusual form, this has some chipping and some rehealed areas that can hidden by angle of display. The edge modifications and faces on this Azurite are very unusual for Tsumeb and in fact for any locality.
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.
