Fluorapatite on Muscovite
stock #16.1-311
Panasquieira Mines, Panasquiera Covilha
Castelo Branco District, Portugal
5.4 x 3.2 x 2.6 CM (cabinet)
price: $400
Spring 2017

Sharp purple Apatites are scattered on a finger of fine grained muscovite in an esthetic grouping. Crystals reach 1.7 CM and most show good color zoning. A choice small cabinet specimen that displays well from the classic mines of Panasquiera. One small contact can be found on a lower edge otherwise this is in perfect undamaged condition.
Gersdorffite with Annabergite
stock #16.1-298
Alt Ahmane, Bou Azer, Tazenakht, Ouarzazate Province
Souss Massa Draa Region, Morocco
4.2 x 3.5 x 2.7 CM (miniature)
price: $760
Spring 2017

Gersdorffite in good or sizable crystals has been super rare until this one small discovery. This is a very fine piece and is the best example we have had from the world class 2014 Bou Azzer find. Sharp lustrous octahedra in a cluster with contrasting green Annabergite shows this Nickel specie well. A brittle mineral, this has some cracks and chipping on some crystals but overall is in exceptional condition. Sharp crystals to 2.3 CM is quite impressive for this specie.
Diamond - Three crystals, different colors and habits
stock #15.1-655
Kimberly, Francis Bard District
Northern Cape Province, South Africa
.3 x .3 x .2 CM largest (thumbnail)
price: $300
Spring 2017

A group of three Diamond crystals, each with a slightly different color hue and very different crystal habits. From an old collection, these total 1.55 Carats. The largest crystal is a penetration twin cube the middle size is a cube with half of its faces having hopped indents and half with growth hillocks and the thirst seems like a cyclic discoidal twin. Under magnification many small modifications and extra faces are seen. Sharp and a nice suite of Carbon!
Tarnowitzite with Cerussite and Galena
stock #15.1-1040-(SM2831)
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oriental Region, Morocco
8.7 x 5.5 x 6.3 CM (cabinet)
price: $550
Spring 2014

A superb Tarnowitzite cabinet specimen from Touissit that has no damage and great esthetics. The matrix is nearly all Tarnowitzite, with minor clear Cerussite and Galena. All the smaller crystals are perfectly transparent, the larger ones are typical milky and very sharp. Touissit has been closed for decades but for a short while it produced some of the worlds finest Plumbo- Aragonites rivaling the best from Tsumeb.This is an especia;lly choice specimen that displays well from all sides. Ex Charles Noll collection with several additional old labels included.
Pyrrhotite replaced by Pyrite and or Chalcopyrite
stock #6.2-566
Yaogangxian Mine, Yizhang County
Hunan Province, China
5.5 x 4.2 x 3.3 CM (cabinet)
price: $120
Spring 2017

An oddity from the great Yaoganxian mine, sharp rosettes of Pyrhotite (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 speciems 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 #17.1-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 V. 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.
