Pyrrhotite replaced by Pyrite and or Chalcopyrite
stock #6.2-566
Yaogangxian Mine, Yizhang County, Chenzhou Pref.
Hunan Province, China
5.5 x 4.2 x 3.3 CM (cabinet)
price: $120
Spring 2017

An oddity from the great Yaogangxian Mine, sharp rosettes of Pyrrhotite (rare at this locale) that are coated by secondary Sulphides and associated with Chalcopyrite and Pyrite. The Pyrrhotite has been partly or entirely replaced by what is likely pyrite but could also be Chalcopyrite. Both species are on the specimen's matrix. Delicate and well-formed this was part of a small find we obtained at the mine in 2003. I have not seen these since then. Uncommon and a nice example for any good Yaogangxian suite.

Wulfenite with Mimetite
stock #AX-21-052
Rowley Mine, (Reliance Mine), Theba, Painted Rock District
Arizona, United States
4.6 x 3.4 x 2.4 CM (miniature)
price: $700
Spring 2017

An excellent, fine, delicate and colorful specimen of windowpane Wulfenite on matrix. A few tiny bits of Mimetite are found on close inspection. In incredible condition for such a delicate mineral, with good magnification I can find only one tiny chipped crystal that is out of sight anyway, essentially perfect. This was found in the last mining attempts at Rowley, that project is now finished and there may never be any more of these. A clean, classic and very esthetic specimen.

Cuprite - large well-crystallized mass
stock #16.1-355
Red Dome Mine, Chillagoe, Tablelands Region
Queensland, Australia
7.8 x 6.2 x 3.8 CM (cabinet)
price: $460
Spring 2017

A sizable pure mass of Cuprite, nearly all crystallized with individual crystals reaching 1.5 CM. A few small vugs have some hairy Cuprite var. Chalcotrichite, in excellent condition overall, this is a rich specimen from a classic locality. Better in person.

Manganite
stock #15.1-452
Ilfeld, Nordhausen, Harz Mts
Thuringia, Germany
5.7 x 4.1 x 2 CM (cabinet)
price: $320
Spring 2017

A fine, old German Manganite with very lustrous metallic crystals. Looks good on all sides but the "front" is a bit better. Typical crystal habits reaching to 3.3 CM. Some contacts and breakage keeps the price very low for one of these classics yet this still displays quite well.

Fluorite - new find
stock #16.1-768
Hameda, Jorf, Er Rachidia Province
Meknes-Tafilalet Region, Morocco
7.9 x 5.8 x 3.9 CM (cabinet)
price: $300
Spring 2017

Glassy bright yellow Fluorite with sharp transparent cubes in an esthetic cluster. From a new find in the Hameda area that has produced much better than previous specimens. Choice display specimen with distinctive habit and color. All of the main crystals are perfect, undamaged which is rare in a Moroccan Fluorite.

Rhodochrosite - scalenohedral gem crystal
stock #16.1-199
Uchucchacua Mine, Oyon Province
Lima Department, Peru
2.5 x 1.2 x .8 CM (thumbnail)
price: $475
Spring 2017

A choice single scalenohedral Rhodo crystal with a small bit of matrix adhering to the back and bottom. Super bright color and sharp, glassy prism faces. The lower termination has some contacts on the back side but otherwise this is in super fine condition and the front side displays very clean as seen. An excellent Peruvian thumbnail that looks a bit like a South African. Choice.

Vesuvianite - doubly terminated - ex Neal Yedlin etc.
stock #16.1-764
Sierra de la Cruz, Municipio de Sierra Mojada
Coahuila, Mexico
4.5 x 3.1 x 3.3 CM (miniature)
price: $90
Spring 2017

A complete "floater" of doubly terminated Vesuvianite that is textbook perfect, from what was long called Lago de Jaco in Coahuila, Mex. but is now considered to be Sierra de la Cruz. This has a fine and long pedigree, it has labels from Neal Yedlin, Ron Bentley, Bud Webster etc. No damage, a few crude Grossular are sprinkled on the prism faces. Likely vintage 1960s, no more have been found for decades.

Fluorite - complex etched cube
stock #0622-JM-2450
Madoc, Centre Hastings, Hastings County
Ontario, Canada
5.8 x 4.9 x 3.7 CM (cabinet)
price: $330
Spring 2017

A complete cube, fully transparent of a pale green Fluorite that has stepped, etched and recrystallized geometric hills on all faces. From old finds at Madoc, this was in the John Marshall collection. One back corner has a tiny bit of matrix adhering and some contacting too, the front and sides are in perfect, undamaged condition. Displays well, few Fluorite collections have this nice a specimen of this classic locale.
