Galena with Sphalerite , Calcite
stock #17.1-240
Pitcher, Ottawa County
Oklahoma, United States
9.3 x 5.2 x 4.4 CM (cabinet)
price: $350
Dec 2018

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.
Diaspore - classic US
stock #8.1-415
Chester Emery Mine, Chester, Hampshire County
Massachusetts, United States
4.4 x 3.3 x 2.4 CM (miniature)
price: $175
Dec 2018

Nearly pure, this is almost all Diaspore crystals with a small area of Amesite matrix, a classic Chester Emery Mine specimen with good lilac color. Typical tightly bundled crystals that have showing over 2 CM across. A single red Rutile needle is also present, Choice condition the Diaspore of this mine were for a time the best known in the world and were very sought after. Later finds eclipsed these but the Chester habit is still unique and it is the type locale for Amesite. A nice specimen that is better than just a locality piece, classic and choice.
Tremolite (Chantoyant crystals)
stock #18-AX-18-247
Pierrpont, St. Lawrence County
New York, United States
5.9 x 4.1 x 3 CM (cabinet)
price: $290
Dec 2018

Sharp, glassy, with catseye effect luster and very well formed, a pure mass of Tremolite crystals. From the now classic Pierrepont locality in St Lawrence county New York, this has fine deep olive green color and is in excellent condition. Collected more 40 years ago by S. Alverson, the chantoyance or catseye effect is striking in person.
Pyrargyrite with Polybasite, Siderite, Pyrite
stock #18.1-409
Porco, Agua de Cstilla, Quijarro Province
Potosi, Bolivia
3.4 x 2.2 x 1.1 CM (small miniature/ large thumbnail (toenail))
price: $400
Dec 2018

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
