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 area, 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”

Main crystal size: 2.9 × 1.9 cm = 1.14” × 0.75”
