TG76L1: Octahedral Fluorite with Quartz and Mica

Group of translucent octahedral Fluorite crystals, on a smoky Quartz crystal. The sample is from a locality where nowadays is quite difficult to obtain specimens.
Kara-Oba mining district, Betpak-Dala (Bet-Pak-Dala) Desert, Karaganda Region Kazakhstan (±1993)
Specimen size: 6.7 × 4.4 × 3.3 cm = 2.64” × 1.73” × 1.30”

FC56AM0: Octahedral Fluorite with Quartz and Pyrite after Pyrrhotite

Octahedral Fluorite crystals, one of them dominant, with very well defined faces and edges, transparent and with a uniform light green color. On matrix with Quartz crystals and a group of very sharp pseudomorphs of Pyrite after Pyrrhotite crystals with a clearly hexagonal outline.
The specimen comes from the Jan Buma collection (number 980612) whose file card we will send to the buyer.
Dalnegorsk, Dalnegorsk Urban District, Primorsky Krai Russia

Main crystal size: 1.4 × 1.3 cm = 0.55” × 0.51”

MP88AJ9: Octahedral Fluorite with Quartz, Calcite and Dolomite

A very well balanced sample which spotlights their transparency and the luster and diaphaneity of the octahedral Fluorite crystals beveled by the dodecahedron and the cube, and the right matrix with Quartz, Calcite and Dolomite.

Specimen size: 6.4 × 3.2 × 5.3 cm = 2.52” × 1.26” × 2.09”

FB66G6: Octahedral Fluorite with Quartz, Ferberite and Muscovite

The crystal of Fluorite were determined to grow just in the middle, and they did. Between the Quartz and the matrix is possible to distinguish, tenaciously growing, the faces of the Fluorite octahedron and cube with marked bluish zones. The matrix is a tapestry of different crystals which give life to the piece.
The specimen has been published in the book 'China', by Berthold Ottens, on page 455.
Yaogangxian Mine, Yizhang, Chenzhou Prefecture, Hunan Province China (±2002)
Specimen size: 11 × 5.5 × 6.5 cm = 4.33” × 2.17” × 2.56”

Main crystal size: 2.9 × 2.5 cm = 1.14” × 0.98”

TZ57AB6: Octahedral Fluorite with Quartz, Pyrite and Chlorite

Aggregate of very sharp octahedral Fluorite crystals, a very rare shape for Panasqueira. They are almost colorless, transparent, and have deep violet cubic phantoms. They are on a crystalline Quartz matrix partially coated by Chlorite, with small Muscovite aggregates and Pyrite crystals. The upper levels of Panasqueira are currently offering surprising and pleasant novelties, with samples that are very different from what has been known from this mine.
Minas da Panasqueira, level 0, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro Region Portugal (01/2015)
Specimen size: 5.6 × 3 × 3.2 cm = 2.20” × 1.18” × 1.26”

FB96K9: Octahedral Fluorite with Schorl and Albite

Octahedral crystal with rounded edges, intense green color, on a Albite matrix with small Schorl crystals.
Dassu, Braldu Valley, Shigar District, Gilgit-Baltistan (Northern Areas) Pakistan
Specimen size: 4.2 × 3.4 × 3.2 cm = 1.65” × 1.34” × 1.26”

FH66T3: Octahedral Fluorite with smoky Quartz

Group of octahedral crystals of Fluorite, with very well defined faces and edges and clear lilac color, very unusual for the samples from the area. They are on matrix, with smoky Quartz and Albite.
The specimen has been published in the magazine ‘extraLAPIS’ on page 41, number 44, "Uri".
Fellital (Felli Valley), Reuss Valley, Uri Switzerland
Specimen size: 9 × 8.6 × 3.9 cm = 3.54” × 3.39” × 1.54”

EB51G4: Octahedral Fluorite with smoky Quartz and Albite

In this Fluorite the color and definition of faces and edges are excellent. Fluorite crystal is enhanced by a group of doubly-terminated smoky Quartz crystals with microcrystals of Albite, all in a matrix, also of Albite.
Göscheneralp, Göschenen Valley, Göschenen, Reuss Valley, Uri Switzerland (1986)
Specimen size: 4.7 × 4.1 × 3 cm = 1.85” × 1.61” × 1.18”

Main crystal size: 1.8 × 1.3 cm = 0.71” × 0.51”

FQ46G6: Quartz after Octahedral Fluorite

In a first view, as a Quartz, it looks rare. And it is rare, because it has the form of octahedral Fluorite, previously existing and substituted by the Quartz. More curious is to observe that the surface is cryptocrystalline Quartz (Chalcedony) but the core of the octahedron, where Fluorite primarily was, is hollow and consists of little geodes covered by Quartz crystals.
Wheal Mary Ann, Menheniot, Liskeard, Cornwall England / United Kingdom
Specimen size: 7.5 × 6.4 × 3.3 cm = 2.95” × 2.52” × 1.30”

TD11F2: Rounded Fluorite

The rounded formations are notable for the variation on color, between lilac and light gray-green. They sit on a long matrix and contrast with the white Quartz and darker host rock.
Buxières-les-Mines, Moulins, Allier, Auvergne-Rhône-Alpes France (2004)
Specimen size: 7.5 × 4.5 × 3.5 cm = 2.95” × 1.77” × 1.38”

JF89X9: Smoky Quartz with octahedral Fluorite and Pyrite

Aggregate of very sharp octahedral Fluorite crystals with abundant inclusions. They are on a group of smoky Quartz crystals, with small cubic Pyrite crystals. It is currently very difficult to obtain good samples from this locality.
Kara-Oba mining district, Betpak-Dala (Bet-Pak-Dala) Desert, Karaganda Region Kazakhstan (±1993)
Specimen size: 13.2 × 8.3 × 8.5 cm = 5.20” × 3.27” × 3.35”

N13BH5: Tetrahexahedral Fluorite with Baryte

Crystals, being small, show an astonishing sharpness of tetrahexahedron, a rare single form on Fluorite because generally it is combined with some other forms. Crystals are uncolored, bright and completely clear and are scattered over an esthetic matrix of white crystals of Baryte.
Jaimina Mine, Obdulia vein, Caravia mining area, Trechorio, Carrales, Caravia, Comarca del Oriente, Principality of Asturias (Asturias) Spain (1996)
Specimen size: 8.4 × 6.4 × 5.3 cm = 3.31” × 2.52” × 2.09”

Main crystal size: 0.6 × 0.4 cm = 0.24” × 0.16”

NC96F0: Tetrahexahedral Fluorite with Baryte

The crystals are tetrahexahedral although this is not very obvious given the subsequent growth of the faces of the basic cube. Near the edges of the crystals there is a fine violet color zone. The crystals, for all their considerable size, are transparent enough to allow one to see the Baryte inclusions.
Jaimina Mine, Obdulia vein, Caravia mining area, Trechorio, Carrales, Caravia, Comarca del Oriente, Principality of Asturias (Asturias) Spain (1996)
Specimen size: 13.5 × 11 × 7.5 cm = 5.31” × 4.33” × 2.95”

FD60H2: Twinned Fluorite

Group of twinned crystals of Fluorite, with the typical deep green color of the old samples from the locality. The specimen was on Martín Oliete collection. Martín purchased it in 1976 from Bailey Minerals.
Heights Quarry, Westgate, Weardale, North Pennines Orefield, County Durham England / United Kingdom (±1976)
Specimen size: 4.2 × 3.2 × 3 cm = 1.65” × 1.26” × 1.18”
