Specimen size: 6.5 × 8 cm = 2.56” × 3.15”

NE58G8: Fluorite on Quartz

Color and luster are, maybe, less intense than usual but compensated by the esthetical aspect of the piece, aerial on a fine matrix of Quartz, and the shape of the faces, that are clear on their beveled edges.

Specimen size: 6.7 × 5.7 × 3.7 cm = 2.64” × 2.24” × 1.46”

FD16F5: Fluorite on Quartz

When one thinks of a Fluorite one does not tend to imagine one like this: on a bed of milky gray Quartz there is a curious group of spherical Fluorite that is decorated by small crystals of Gyrolite and Fluorapophyllita-(K).
Mahodari, Nashik District (Nasik), Maharashtra India (±1999)

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

FC17G6: Fluorite on Quartz

It looks like a mushroom growth but it’s not. It’s spherical orange Fluorite on a gray matrix of Quartz giving a nice color contrast. The Quartz covering the matrix shows the dark color of the rock giving to the sample a velvet aspect.
Mahodari, Nashik District (Nasik), Maharashtra India (2004)
Specimen size: 10 × 7 × 3.8 cm = 3.94” × 2.76” × 1.50”

FB36G6: Fluorite on Quartz

Between the Quartz crystals appears a sphere of Fluorite and, furthermore, from the same sphere starts some sceptered Quartz, different in its color and shape to the Quartz on the matrix. The lower part of the piece is hollowed, as if it growth was covering an older material.

TV68E0: Fluorite on Quartz

A large specimen with a very large spherical Fluorite (in fact one of the largest we have seen.) It also has a pleasant cream color along with good development of the sphere, which stand proud of the matrix. There is also a bit of brown Calcite at the base of the specimen.
The specimen's photo has been reviewed and published in the magazine ‘Rocks & Minerals’ on page 299 in the volume 83, number 4.
Mahodari, Nashik District (Nasik), Maharashtra India (2003)
Specimen size: 11 × 8.5 × 4 cm = 4.33” × 3.35” × 1.57”

NK61G8: Fluorite on Quartz

Isolated, very sharp crystals, enhancing the color zones that show different growth phases. Fluorite crystals, very bright and transparent, are on a matrix of little Quartz crystals.
Jaimina Mine, Obdulia vein, Caravia mining area, Trechorio, Carrales, Caravia, Comarca Oriente, Principality of Asturias (Asturias) Spain (2002)
Specimen size: 5.4 × 4 × 2.3 cm = 2.13” × 1.57” × 0.91”

Main crystal size: 1 × 0.9 cm = 0.39” × 0.35”

FA58G0: Fluorite on Quartz

Crystals of extraordinary color are composed of the cube and dodecahedron but neither form predominates. The contrast with Quartz matrix, partially dissolved by acid, is superb.
The specimen has been published in the book 'China', by Berthold Ottens, on page 47.
De'an Mine, Wushan, De'an, Jiujiang Prefecture, Jiangxi Province China (±2002)
Specimen size: 10.3 × 8 × 5 cm = 4.06” × 3.15” × 1.97”

EB69F0: Fluorite on Quartz (Opal)

An uncommon crystal form with a balance between the cube and the octahedron. The crystal has been made visible by dissolving some of the Quartz matrix (partially transformed into opal) with acid, which has been used carefully so that, unlike in so many other cases, this one looks quite natural.
Wushan, De'an, Jiangxi China (2003)
Specimen size: 11.5 × 9.5 × 6 cm = 4.53” × 3.74” × 2.36”

Main crystal size: 4.8 × 5 cm = 1.89” × 1.97”

FB47F7: Fluorite on Quartz (variety amethyst)

Gentle colors. The crystals of Quartz have growth phantoms that are more violet, and also inclusions of Chalcopyrite. Among the Quartz there are some crystals of yellow Fluorite, which give a neat and gentle contrast. While the Jan Buma label says that this comes from El Hammam, we think it must be from Aouli even though it is different from the latest material we have seen from that locality.
Aouli, Mibladen mining district, Mibladen, Midelt, Midelt Province, Drâa-Tafilalet Region Morocco (±2002)
Specimen size: 10 × 8 × 6 cm = 3.94” × 3.15” × 2.36”

NXM37AO7: Fluorite on Quartz (variety red quartz)

This specimen has unusual characteristics for La Viesca Fluorite, and comes from the collection of Miguel David Martínez (number 865), whose label we will send to the buyer.
La Viesca Mine, La Collada mining area, Huergo, Siero, Comarca Oviedo, Principality of Asturias (Asturias) Spain
Specimen size: 5.8 × 3.5 × 2.7 cm = 2.28” × 1.38” × 1.06”

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

TXM27AN3: Fluorite on Quartz (variety smoky)

Fluorite crystals of unusual habit and color for alpine specimens, dominated by cube forms, beveled by the rhombic dodecahedron. Transparent, with a violet color, on a matrix of smoky Quartz crystals. The specimen is from the Alain Martaud collection.
Aiguille Verte, Mont Blanc Massif, Chamonix, Haute-Savoie, Auvergne-Rhône-Alpes France (2015)
Specimen size: 4.3 × 3.9 × 3.4 cm = 1.69” × 1.54” × 1.34”

MRR68CD3: Fluorite on Quartz and Calcite

Deep blue cubic Fluorite crystals, translucent, with smooth faces, and beveled by the rhombododecahedron that presents a rough and a much more intense, almost blackish coloration, which is distinctive of the specimens from the Josefa-Veneros vein in La Collada. On a matrix formed by scalenohedral crystals of white Calcite and small Quartz crystals. A classic specimen from this locality that is acquiring a certain mythical halo with the passage of time.
Josefa-Veneros vein, 75 level, Coroña de Arriba-La Collada, La Collada mining area, Siero, Comarca Oviedo, Principality of Asturias (Asturias) Spain
Specimen size: 4.5 × 3.3 × 2.3 cm = 1.77” × 1.30” × 0.91”

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

B62RH2: Fluorite on Quartz with Calcite

On a base of Quartz crystals stand some groups of echeloned crystals of Fluorite made of small cubes with beveled edges and deep blue color. All over the matrix there are other small single cubes also with beveled edges. A classic sample from the mythic Josefa-Veneros Norte vein, at La Collada.
Josefa-Veneros vein, 75 level, Coroña de Arriba-La Collada, La Collada mining area, Siero, Comarca Oviedo, Principality of Asturias (Asturias) Spain (1975)
Specimen size: 13.2 × 7.5 × 5.2 cm = 5.20” × 2.95” × 2.05”

NP6AF3: Fluorite on Quartz with Chlorite

Group of very flattened Fluorite crystals with the very well defined forms of the cube and dodecahedron. The Fluorite, with a lilac-blue color, has grown partially following the forms of the Quartz crystal where it is covering it. The Quartz crystal is partially coated by chlorite near the base. 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.
The Fluorite has been analyzed and we’ll send a copy of the analysis to the buyer.

EB66K0: Fluorite on Quartz with Opal

Huge complex ball of Fluorite on Quartz with a plus: some minor fluorescent Opal covering the Quartz on the right side of the specimen, and a thick coating of fluorescent Opal is included inside the Fluorite ball contrasting with it, due to its intense pearly white color. Different!.
The specimen's photo has been reviewed and published in the magazine ‘Rocks & Minerals’ on page 301 in the volume 83, number 4.

FA6G6: Fluorite on Schorl

The crystallization of this Schorl features acicular forms and, just with the green Fluorite crystals, the mélange of the two minerals is a nice contrast. The crystals of Fluorite have a complex form.
Davib East Farm 61 (Davib Ost Farm), Karibib District, Erongo Region Namibia (12/2001)
Specimen size: 8 × 3.7 × 2.9 cm = 3.15” × 1.46” × 1.14”

Main crystal size: (Fluorite) 0.6 × 0.6 cm = 0.00” × 0.24”

FR76G0: Fluorite on Siderite

A rarity! Although Fluorite is known from Panasqueira, it rarely forms such well defined and deep colored crystals as in this specimen. The matrix is, furthermore, specially esthetic being rich in little crystals of Siderite.
Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro Portugal (1998)
Specimen size: 5.2 × 5.1 × 3.4 cm = 2.05” × 2.01” × 1.34”

NF97AF3: Fluorite on Topaz and Arsenopyrite with Quartz
