JFD75AO0: When I bought this very unusual piece I had many illusions because of its alleged rarity and, as often happens, analyses demolished my illusions. It's a Pyrite, just Pyrite, but it's weird as hell, right?
Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (±1988)

Specimen size: 7.1 × 3.9 × 3.7 cm = 2.80” × 1.54” × 1.46”

Main crystal size: 3.1 × 2.6 cm = 1.22” × 1.02”

JFD80AO0: Less famous than Touissit or Mibladen, Taouz cerussites can be attractive too. In this case, although the very aerial crystals are small, their snow-white color contrasts with the dark matrix in which there are small Quartz crystals with inclusions of iron oxides.
Taouz, Er Rachidia Province, Drâa-Tafilalet Region  Morocco (±1990)

Specimen size: 6.4 × 3.7 × 2 cm = 2.52” × 1.46” × 0.79”

Main crystal size: 0.9 × 0.8 cm = 0.35” × 0.31”

JFD82AO0: The Bou Nahas mine produced many pyrites and barytes early in its history. Out of so much material I chose this piece, with the Baryte crystal isolated on the Quartz and with a slight bluish central thread unlike the first barytes from there, which had more yellow tones.
Bou Nahas Mine, Oumjrane mining area, Alnif Commune, Tinghir Province, Drâa-Tafilalet Region  Morocco (12/2011)

Specimen size: 6.3 × 5.1 × 4.7 cm = 2.48” × 2.01” × 1.85”

Main crystal size: 4.3 × 2.8 cm = 1.69” × 1.10”

JFD84AO0: Very interesting specimen for this mine because the very aesthetic Calcite crystals sit on large Baryte crystals coated by what look like orange iron oxides and are accompanied by small Pyrite crystals. Baryte is not a common mineral in El Hammam, I have rarely seen it there, much less in large crystals as in this case. As sometimes happens, I didn't buy it in Morocco but in Tucson 2009, from the Moroccan Ahmed Es Seouani.
El Hammam, Ait Mimoune, Khémisset Province, Rabat-Salé-Kénitra Region  Morocco (11/2008)

Specimen size: 9 × 8.2 × 7.7 cm = 3.54” × 3.23” × 3.03”

Main crystal size: 1.7 × 1.4 cm = 0.67” × 0.55”

TBR56AO0: Parallel growth of sharp Axinite (Group) crystals, translucent, with good luster and an excellent smoky color with violet tones.
We will ship the specimen in its original Perky box from the Robert J. (Bob) Noble collection, which also contains the label.
Bor Pit, Dalnegorsk B deposit, Dalnegorsk, Dalnegorsk Urban District, Primorsky Krai  Russia

Specimen size: 3.1 × 1.8 × 1.2 cm = 1.22” × 0.71” × 0.47”

TLB6AO0: Group of tabular Fluorapatite crystals with sharp crystal forms, translucent, with good luster and a uniform white color.
We will ship the specimen in its original Perky box from the Robert J. (Bob) Noble collection, which also contains the label.
Ánimas Mine, Ánimas , Chocaya, Municipio Atocha, Sud Chichas Province, Potosí Department  Bolivia

Specimen size: 2.2 × 1.7 × 1.3 cm = 0.87” × 0.67” × 0.51”

Main crystal size: 2 × 1.4 cm = 0.79” × 0.55”

TPM76AO0: Group of crystals, with one of them clearly dominant and all of them doubly terminated, totally occupied by inclusions of sand. They are formed by a prism with curved edges and a poorly defined terminal rhombohedron. An American classic which it is currently very difficult to obtain in good specimens as the area in which they were found has been declared a National Park.
Rattlesnake Butte, Jackson County, South Dakota  USA

Specimen size: 9.3 × 6.7 × 4.5 cm = 3.66” × 2.64” × 1.77”

Main crystal size: 7.6 × 3 cm = 2.99” × 1.18”

TFB87AO0: Spheroidal growths of Smithsonite, on matrix, translucent, with a satin luster and a uniform bluish green color. An American classic.
Kelly Mine, Magdalena, Magdalena District, Socorro County, New Mexico  USA

Specimen size: 8.2 × 5.4 × 4.2 cm = 3.23” × 2.13” × 1.65”

EDX48AO0: Spheroidal nodules of Pyrite crystals with the dominant faces of the octahedron, very shiny, included in a carbonaceous matrix.
State Bridge area, Rocky Mountain, Eagle County, Colorado  USA

Specimen size: 7.6 × 6.3 × 4.4 cm = 2.99” × 2.48” × 1.73”

Main crystal size: 2.9 × 2.3 cm = 1.14” × 0.91”

MTL89AO0: Druse of twinned Sphalerite crystals with very well defined faces and edges, translucent, very bright and with dominant orange tones, with yellow reflections. On matrix, with small Galena crystals and twinned Chalcopyrite crystals. An American classic from a locality from which it is currently very difficult to obtain good specimens.
Commodore Mine, Creede District, Mineral County, Colorado  USA

Specimen size: 8.4 × 6.4 × 2.8 cm = 3.31” × 2.52” × 1.10”

Main crystal size: 1.2 × 1 cm = 0.47” × 0.39”
