	Octahedral Fluorite on Quartz
FF13H0: Both the matrix of little Quartz crystals and the Fluorite octahedron have a glazed surface. The Fluorite crystal is easy to distinguish by its light green color and the good position on the matrix, but another crystal, nearly uncolored, is hidden there too. As usually happens with a lot of samples from Jan Buma’s collection, the locality is very unusual. Oregon Mine, Oatman District, Mohave County, Arizona  USA (±2002) Specimen size: 5.4 × 4.6 × 3.4 cm Main crystal size: 1.5 × 1.4 cm Fluorescent long & short UV Former Jan Buma collection.

	Fluorite with Quartz
FT16F7: Crystals of fluorite surround it right to the top. Maybe they were trying to purify themselves as they have a phantom within them. But that would not have been easy as the road was full of spines.... of Quartz, of course. Such thoughts aside, the Fluorite has an excellent color and is from a classic locality, which is famous for its exceptional Rhodochrosite. Sweet Home mine, Alma, Colorado  USA (±2001) Specimen size: 5.4 × 4 × 3.6 cm Main crystal size: 0.3 × 0.3 cm Minor fluorescence long & short UV Former Jan Buma collection. Number 011022	Front Side

There is also a “phantom” growth with a more opaque central zone. The crystals are on a matrix of Rhodochrosite, Quartz and small crystals of Chalcopyrite. The sample is with the label of the collection of Fluorites of Herb Obodda. American Tunnel Mine, Howardsville, San Juan County, Colorado  USA Specimen size: 6.6 × 4.9 × 5.1 cm Main crystal size: 3.5 × 3.2 cm Fluorescent long & short UV Former Jan Buma collection. Number 010427	Front Top

Mexico - Canada

Fluorite with Pyrrhotite and Quartz
	FA14H8: Crystals are octahedrons, and have stepped growths due to the presence of small faces of the cube, both on the edges and the faces. The matrix, on which there are also small crystals of Quartz, is formed for a group of hexagonal crystals of Pyrrhotite, well defined, neat, bright and free of alteration. Santa Eulalia, Chihuahua  Mexico (±1996) Specimen size: 6.5 × 4.9 × 4.5 cm Main crystal size: 0.8 × 0.7 cm Former Jan Buma collection. Number 960805

	Fluorite with Galena, Arsenopyrite and Calcite
FD29H0: A bright piece, the Galena, Arsenopyrite, and the Fluorite as well, the Fluorite is gemmy and slightly green colored.

Naica, Saucillo, Chihuahua  Mexico (±1980) Specimen size: 7.7 × 5.5 × 4.1 cm Main crystal size: 3.5 × 2.9 cm Former Jan Buma collection. Number 020801

Fluorite with Calcite and Jamesonite inclusions
Front Top	FE86F7: In this case I like the form of the Fluorite, it looks like a stepped tower, and also the crown of white Calcite near the top of it. I also like the fact that within it you can also see needlelike crystals of Jamesonite. A very good specimen for the locality. Mina San Martín, Sombrerete, Zatatecas  Mexico (±2004) Specimen size: 5.3 × 4.3 × 4.4 cm Main crystal size: 2 × 2 cm Calcite extremely fluorescent long & short UV Former Jan Buma collection.

Spain

	Calcite with Dolomite and Fluorite
FC16G6: Really Nature has its own caprices! I think this piece is a good example. Dolomite crystals form a "pompon" on the top of a Calcite scalenohedron. Furthermore there are some Fluorite crystals and one of them, as it must be, on the "pompon". Mina Emilio, El Fito, Loroñe, Asturias  Spain (±1998) Specimen size: 11 × 6.3 × 7 cm Former Jan Buma collection. Number 980919

Fluorite with Quartz

Geoda del Reguerín 2, la Viesca, La Collada, Asturias  Spain (12/2001) Specimen size: 9.3 × 7.2 × 4.6 cm Main crystal size: 1.6 × 1.5 cm Former Jan Buma collection. Number 021022

	Fluorite
FN87F5: A Spanish classic. From the Veneros Norte Mine at La Collada, which is now closed, comes this large crystal (a floater) that is recrystallized on the rear and that has the typical bevelled edges of this mine. A deep violet color, but in fact even more interesting as one can feel the depth of it due to the bluer zone in its center. Filón Josefa-Veneros Norte, La Collada, Asturias  Spain (±1974) Specimen size: 8.3 × 8 × 6 cm Former Jan Buma collection. Number 990401

Panasqueira

Fluorite on Siderite
	FR76G0: 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, Beira Baixa  Portugal (1998) Specimen size: 5.2 × 5.1 × 3.4 cm Main crystal size: 0.6 × 0.6 cm Fluorescent long & short UV Former Jan Buma collection. Number 901027

Number 030504

	Quartz after Octahedral Fluorite
FQ46G6: 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 Main crystal size: 1.5 × 1.5 cm Former Jan Buma collection. Number 940105

	Fluorite with Zinnwaldite and Quartz
FF86H5: Fluorites from Zinnwald are very rare. The locality is one of the great classics in the history of mineralogy. On the sample the cubes of Fluorite form a crowd on the upper part of the matrix that has Quartz crystals and laminar crystals of Zinnwaldite of pseudohexagonal habit and perfectly sharp. We call attention to Zinnwald as a type locality for Zinnwaldite. The specimen's photo has been reviewed and published in the magazine ‘Rocks & Minerals’ on page 159 in the volume 82, number 2.

Morocco

Fluorite on Dolomite
	FA58F7: A very elegant example and different from the ones we normally see from Aouli. On a bed of small crystals of Dolomite there is a group of very well defined crystals of yellow Fluorite, which have contrasting zones of violet. An exceptional specimen for the locality, as Herb Obodda must have known - it was in his collection with label number 459, we will send to a buyer a copy of our analysis of the specimen.

Africa

	Fluorite
FG63F5: The thing that attracted me to this floater is the strange (and unusual for this locality) color zoning that is between orange and violet, as well as the uneven thickness of the crystals, which makes them look tabular. Okaruso Mine, Otjiwarongo District  Namibia (±1997) Specimen size: 5.5 × 4.5 × 2.5 cm Main crystal size: 1.9 × 1.5 cm Minor fluorescence long & short UV Former Jan Buma collection. Number 970904

Fluorite with Orthoclase and Quartz
	FB61H8: The locality is not so common. Crystals are octahedral and have well defined faces and edges and a curious and irregular distribution of their color, practically uncolored in some zones, and they have spots of an intense violet color in some other. On the matrix there are twinned crystals of Orthoclase and small crystals of smoky Quartz. Formación Papachacra, Departamento Belén, Catamarca  Argentina (±2004) Specimen size: 7.9 × 6.8 × 6.5 cm Main crystal size: 0.8 × 0.7 cm Fluorescent long & short UV Former Jan Buma collection. Number 040904

	Rhodochrosite with Fluorite
FF67K0: Very uncommon association of Rhodochrosite and Fluorite crystals. The Rhodochrosite forms multiple crystals while the Fluorite crystals are rounded and poorly defined with rough surfaces due to complex crystallization. Mina Uchucchacua, Oyon, Departamento de Lima  Peru (±2002) Specimen size: 6.3 × 4.8 × 2.4 cm Main crystal size: 1.3 × 1 cm Former Jan Buma collection. Number 020638

Octahedral Fluorite with Pyrite
	FC76F5: Apart from the fact that it is octahedral, the pink color is great throughout all of it except for the green heart. A small amount of matrix and Pyrite adds to it. Mina Huanzala, Huallanca, Dos de Mayo, Huánuco  Peru Specimen size: 3.3 × 3 × 3.2 cm Fluorescent long & short UV Former Jan Buma collection. Number 010625

	Hübnerite with Fluorite
FZ46I7: Parallel growth of very bright prismatic crystals on a matrix of white crystals of Quartz. On some of the Hübnerite crystals there are small crystals of Fluorite, blue, transparent and very rich in faces. The sample is with two labels, one from Hamel Mining and Minerals, Los Angeles, and the other from the Scott J. Williams collection. Mina Huallapón, Pasto Bueno, Pallasca, Ancash  Peru Specimen size: 7 × 5 × 3.3 cm Main crystal size: 3.5 × 1 cm Fluorite extremely fluorescent long & short UV Former Jan Buma collection. Number 050113

Fluorite with Brazilianite and Albite
	FD76K9: Another of the unusual parageneses to which we are accustomed from the collection of Jan Buma. Beveled cubic crystals on Brazilianite and elongated crystals of white Albite. Linopolis, Divino das Laranjeiras, Minas Gerais  Brazil Specimen size: 7.7 × 5.8 × 3.6 cm Main crystal size: 0.9 × 0.8 cm Fluorescence short UV & low fluorescence long UV Former Jan Buma collection.

China

	Fluorite with Quartz
FK64M0: Fluorite octahedral crystals, one of them dominant, with an intense and vivid color, with small darker crystals with Quartz. On matrix. Xianghuapu Mine, Linwu, Chenzhou, Hunan  China (±2003) Specimen size: 6.6 × 5.3 × 4.7 cm Main crystal size: 3.3 × 3 cm Former Jan Buma collection. Number 031015	Front
