As usually happens with a lot of samples from Jan Buma’s collection, the locality is very unusual. Danville, Boyle County, Kentucky  USA Specimen size: 8 × 6.8 × 5.9 cm = 3.1” × 2.7” × 2.3” Main crystal size: 1.2 × 1 cm = 0.5” × 0.4” Intense fluorescence long & short UV Former Jan Buma collection. Number 041201

	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 = 2.1” × 1.6” × 1.4” Main crystal size: 0.3 × 0.3 cm = 0.1” × 0.1” Minor fluorescence long & short UV Former Jan Buma collection.

Number 931030

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".

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.

FSU

	Ferberite with Fluorite and Pyrite
FD13G0: These Ferberite crystals form a very curious growth in contrast with the matrix of bright Pyrite cubes covering a wide part of the back of the sample. On the Ferberite little Fluorite crystals can be seen. Kara-Oba, Betpakdala, Karaganda Oblast  Kazakhstan (±1993) Specimen size: 5.6 × 5 × 1.7 cm = 2.2” × 2.0” × 0.7” Former Jan Buma collection. Number 930913 Fluorite fluorescent long & short UV

Octahedral Fluorite with Pyrite and Sphalerite
	FB86F9: The crystal is forming a complex growth in two different phases. In the first one the major octahedron formed and then on the octahedron vertices, smaller Fluorite crystals with dodecahedrons grew. Sphalerite and cubes of Pyrite form a perfect base to the sample. The Fluorite has good color and transparency and the referenced locality has become a classic. Kara-Oba, Betpakdala, Karaganda Oblast  Kazakhstan (±1995) Specimen size: 3.9 × 3.5 × 2.7 cm = 1.5” × 1.4” × 1.1” Main crystal size: 2.9 × 2.6 cm = 1.1” × 1.0” Former Jan Buma collection. Number 950303

	Fluorite on Quartz

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. Aouli, Mibladen, Midelt  Morocco Specimen size: 11 × 8.3 × 5.3 cm = 4.3” × 3.3” × 2.1” Main crystal size: 1.5 × 1.5 cm = 0.6” × 0.6” Intense fluorescence long & short UV Former Jan Buma collection. Number 010102

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 = 2.2” × 1.8” × 1.0” Main crystal size: 1.9 × 1.5 cm = 0.7” × 0.6” Minor fluorescence long & short UV Former Jan Buma collection.

Number 040509

	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 = 3.1” × 2.7” × 2.6” Main crystal size: 0.8 × 0.7 cm = 0.3” × 0.3” 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, Oyón, Departamento Lima  Peru (±2002) Specimen size: 6.3 × 4.8 × 2.4 cm = 2.5” × 1.9” × 0.9” Main crystal size: 1.3 × 1 cm = 0.5” × 0.4” 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 = 1.3” × 1.2” × 1.3” Fluorescent long & short UV Former Jan Buma collection. Number 010625

Hübnerite with Fluorite

	Fluorite
FE58F7: Many Fluorites have neat colors but this one really is impressive. The color is very intense and the crystals are very transparent, so you can see the matrix through them. The cubes are quite large and well placed on the matrix. A great one. Xianghualing Mine, Linwu, Chenzhou, Hunan  China (±2003) Specimen size: 9 × 8.5 × 7.5 cm = 3.5” × 3.3” × 3.0” Main crystal size: 3.3 × 2.9 cm = 1.3” × 1.1” Former Jan Buma collection. Number 030621

Fluorite with Calcite
	FA57F7: A contrast of color and forms. I think that the way the Calcite has crystallized is original, with white, lenticular crystals that have grown like mushrooms. Between them there are cubes of intensely lilac Fluorite with modified edges. Shangbao Mine, Leiyang, Hunan  China (±2002) Specimen size: 10.5 × 7 × 5 cm = 4.1” × 2.8” × 2.0” Main crystal size: 1.2 × 0.9 cm = 0.5” × 0.4” Calcite fluorescent long & short UV Former Jan Buma collection.

Number 010675

	Fluorite with Quartz
FH76H5: The transparency of the cubic crystal shows a marked zonation of color, distributed following the cleavage planes, corresponding to octahedron faces, and not in the direction of the edges as is usual. In the center of the crystal the higher intensity of color has a mossy appearance. Matrix is a fine and elegant bed of prismatic crystals of Quartz. Yaogangxian Mine, Yizhang, Chenzhou, Hunan  China (±2002) Specimen size: 10 × 7.3 × 2 cm = 3.9” × 2.9” × 0.8” Main crystal size: 1.6 × 1.6 cm = 0.6” × 0.6” Former Jan Buma collection. Number 020611

Sphalerite with Quartz, Fluorite and Chalcopyrite
	FE16G6: A wall of Quartz crystals with some curious and recrystallized tips giving shelter to rounded Sphalerite. Jan Buma, on his record card, gives the mineral as Stannite. We had doubts, so we analyzed them and the result was they really are Sphalerite. We also emphasize the cubic crystals of Fluorite on the piece - nearly uncolored but with little brush-strokes of intense blue. Yaogangxian Mine, Yizhang, Chenzhou, Hunan  China (±2003) Specimen size: 8.4 × 6.5 × 7 cm = 3.3” × 2.6” × 2.8” Main crystal size: (Sphalerite) 1.9 × 1.6 cm = 0.0” × 0.6” Fluorite fluorescent long & short UV Former Jan Buma collection.

	Fluorite with Quartz, Pyrite and Mica
FT50F6: The crystal is complex, as it combines the basic octahedral with cubic steps creating an Aztec pyramid. Especially notable for the color zoning, light blue in its center and strongly violet on the edges of the cubic faces. The position of the crystal on the matrix of Quartz, Pyrite and Mica make this one really esthetic. Yaogangxian Mine, Yizhang, Chenzhou, Hunan  China (1999) Specimen size: 7.3 × 6.3 × 6.3 cm = 2.9” × 2.5” × 2.5” Former Jan Buma collection. Number 990633	Front Side Top

Octahedral Fluorite with Quartz, Ferberite and Muscovite
	FB66G6: 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, Hunan  China (±2002) Specimen size: 11 × 5.5 × 6.5 cm = 4.3” × 2.2” × 2.6” Main crystal size: 2.9 × 2.5 cm = 1.1” × 1.0” Former Jan Buma collection.

Jalgaon, Maharashtra  India (±1996) Specimen size: 13 × 8 × 4.5 cm = 5.1” × 3.1” × 1.8” Main crystal size: 2.9 × 1 cm = 1.1” × 0.4” Former Jan Buma collection. Number 960907	Front Rear

Apophyllite-(KF) with Julgoldite-Fe inclusions
	JE89E5: Yes, this is an exceptional specimen! The inclusions of Julgoldite-Fe that dye the crystals of Apophyllite-(KF) towards the bottom of the specimen, by the contrast they create, make the transparent ones in the upper half very appealing. While the photo cannot show it, the play of color and reflections is spectacular. Jalgaon, Maharashtra  India (±1988) Specimen size: 9.8 × 7 × 4.7 cm = 3.9” × 2.8” × 1.9” Former Jan Buma Collection. Number 991034

	Apophyllite-(KF) with Stilbite-Ca and Okenite
JY11N1: Pseudocubic green crystals formed by the prism, a dipyramid and the pinacoid. They are on matrix, with Stilbite-Ca, and partially coated by fibrous crystals of Okenite. Lonavala, Maharashtra  India (±2001) Specimen size: 11 × 9 × 3.8 cm = 4.3” × 3.5” × 1.5” Main crystal size: 1.8 × 1.5 cm = 0.7” × 0.6” Former Jan Buma collection. Number 010317 Okenite fluorescent long & short UV

Apophyllite-(KF) with Stilbite and Heulandite
	JZ9N1: Pseudocubic green bright crystals of Apophyllite-(CaK) formed by the prism, a dipyramid and the pinacoid. They are on matrix, with bow-tie growths of Stilbite-Ca and very bright crystals of Heulandite. Pashan Hills, Poona, Maharashtra  India (±2001) Specimen size: 9.4 × 7.1 × 3.4 cm = 3.7” × 2.8” × 1.3” Main crystal size: 2.1 × 1.9 cm = 0.8” × 0.7” Former Jan Buma collection. Number 010304

	Apophyllite-(KF) with Scolecite
JC87E8: An explosion of form and brilliance. For all my experience in color analysis, I cannot quite understand how such gentle colors can result in the superb contrast this specimen has. All the minerals, Apophyllite-(KF), Scolecite and Stilbite, seem to combine with great elegance. The excellent state of the specimen, which looks very fragile and delicate, show how well it has been cared for by those who collected it and have looked after it since. Rahuri, Maharashtra  India (±2002) Specimen size: 14.5 × 9.5 × 6 cm = 5.7” × 3.7” × 2.4” Main crystal size: 2 × 0.9 cm = 0.8” × 0.4” Former Jan Buma collection. Number 021034

Apophyllite-(KF) with Scolecite
	JB68E7: This one deserves a good description. The crystals of Apophyllite-(KF) are very long (prismatic) and seem to fly on the matrix. They are a deep green color. Between them there is something that looks like a coral Aragonite – in reality it is Scolecite. So between these the over effect is pleasing and it would look great in a cabinet display. Rahuri, Maharashtra  India (±2002) Specimen size: 11 × 9 × 5.2 cm = 4.3” × 3.5” × 2.0” Main crystal size: 5.5 × 1.6 cm = 2.2” × 0.6” Former Jan Buma collection. Number 021033

	Apophyllite-(KF) with Stilbite
JV90E5: Elegance and beauty combine in this sample that Jan Buma got in Jalgaon. Luminous, clean, with crystals that appear to be very well defined, given the contrast between the green and the white. Jalgaon, Maharashtra  India (±2000) Specimen size: 7.2 × 5 × 3.7 cm = 2.8” × 2.0” × 1.5” Main crystal size: 1.3 × 0.5 cm = 0.5” × 0.2” Former Jan Buma collection. Number 200410 Stilbite low fluorescence short UV

Cavansite with Stilbite
	JB87E8: Unlike other Cavansites this one has thick tabular crystals that are well separated from each other and are very luminous. They are perfect and well positioned on the Stilbite matrix. Much better than many of the other Cavansites we have seen. Wagholi Quarry, Poona, Maharashtra  India (±2001) Specimen size: 8 × 6.8 × 4 cm = 3.1” × 2.7” × 1.6” Main crystal size: 1.2 × 0.5 cm = 0.5” × 0.2” Former Jan Buma collection. Number 010308

	Calcite on Prehnite
JA76E7: There is good contrast between the yellow Calcite and the green spherical Prehnite. The crystals of calcite are well positioned on the Prehnite matrix and the overall effect is delicate and soothing. A very fine specimen. Malad quarry, Bombay, Maharashtra  India (±2003) Specimen size: 11.5 × 7 × 6 cm = 4.5” × 2.8” × 2.4” Main crystal size: 2 × 1.4 cm = 0.8” × 0.6” Former Jan Buma collection. Number 030612 Calcite intense fluorescence short and long UV

Calcite with Okenite inclusions
	JA96F0: This crystal, a simple scalenohedron, is transparent so one can see something unusual within it: a ‘fuzzball’ of Okenite inclusions! The faces of the crystal are partially covered by green Apophyllite-(KF) and white Stilbite. On the rear the areas of exfoliation do not affect the esthetics of the specimen. Poona, Maharashtra  India (±2002) Specimen size: 11.5 × 8.5 × 9.5 cm = 4.5” × 3.3” × 3.7” Former Jan Buma collection. Number 020851

	Scolecite with Apophyllite-(KF)
JJ88F1: We have often seen in other specimens how Jan's good taste and sensitivity led him to select simple and small examples of the best of each mineral. This is one of the best examples of his style. The radial bundles of Scolecite compete with each other to show off their beauty. The central crystal of Apophyllite-(KF), suspended on a bundle of Scolecite as if by magic, is the final touch to this work of art. Poona, Maharashtra  India (±2000) Specimen size: 20 × 11 × 11 cm = 7.9” × 4.3” × 4.3” Former Jan Buma collection. Number 200406	Front Rear

Gyrolite
	JV58F1: Nodules of snow white Gyrolite surrounding the trunk of Prehnite, which is clear. So white on white, but for all that it has intensity and life. Nasik, Maharashtra  India (±1991) Specimen size: 6.3 × 3.5 × 3 cm = 2.5” × 1.4” × 1.2” Gyrolite fluorescent long & short UV Former Jan Buma collection. Number 910903

	Julgoldite-(Fe) with Apophyllite-(KF)
JV58F2: The rare mineral Julgodite-(Fe) covers the basalt matrix. The small crystals, which are quite dark, are noticeable as they contrast well with the crystals of Apophyllite-(KF), which are doubly-terminated, brilliant, water clear and with sharp pyramids. Jalgaon, Maharashtra  India (±2000) Specimen size: 20 × 13 × 5 cm = 7.9” × 5.1” × 2.0” Main crystal size: 1.4 × 0.5 cm = 0.6” × 0.2” Former Jan Buma collection. Number 201016

Elbaite with Lepidolite
	JB6E8: A well formed sample that is three centimeters tall. The Elbaite crystal is well defined and the crystals of Lepidolite give it an elegant touch. Pala, San Diego County, California  USA (±1979) Specimen size: 3.2 × 1.9 × 1.7 cm = 1.3” × 0.7” × 0.7” Former Jan Buma collection. Number 79077

	Calcite doubly terminated
JH14E5: This one appeals to me because it is unusual. The Calcite crystals, which are very well defined, doubly terminated, and clear, appear to be randomly spread across the dark matrix. Minerva I Mine, Cave in Rock, Illinois  USA (±1980) Specimen size: 8.8 × 6 × 6.5 cm = 3.5” × 2.4” × 2.6” Main crystal size: 2.9 × 0.9 cm = 1.1” × 0.4” Former Jan Buma collection. Number 79098 Fluorescent long UV

Limonite after Pyrite
Front Rear	JD36E3: All the pseudo minerals I have seen seem rather mat to me, and when one is dealing with limonite they tend to have an earthy look. So this one stands out for the surprising brilliance and its achitecture, which is very fine. Pelican Point, Utah city, Utah  USA (±1996) Specimen size: 4.4 × 3.2 × 3.6 cm = 1.7” × 1.3” × 1.4” Main crystal size: 2.1 × 2 cm = 0.8” × 0.8” Former Jan Buma collection. Number 960905

	Pyromorphite
JX63F1: A small, complete specimen that has all the features typical of its bigger brothers. So it is a good example for those people who love miniatures, above all else for its intense color. Bunker Hill Mine, Kellog, Idaho  USA (±1995) Specimen size: 1.7 × 1.3 × 1.5 cm = 0.7” × 0.5” × 0.6” Main crystal size: 0.5 × 0.5 cm = 0.2” × 0.2” Former Jan Buma collection. Number 950302

Silver with Calcite
	JA26E8: For its size the sample is really precious. Like a fossilized crystal of fern, the Silver surrounds the Calcite matrix, both of which sit on a fragment of rock that acts as its matrix. Batopilas, Chihuahua  Mexico (±1993) Specimen size: 3.6 × 2.5 × 2 cm = 1.4” × 1.0” × 0.8” Former Jan Buma collection. Number 930502

	Quartz (Amethyst)
JA13E5: This elegant specimen appealed to me because of its nice color hints. With thin matrix on which the, sometimes doubly terminated, crystals of amethyst grow. Las Vigas, Veracruz  Mexico (±1979) Specimen size: 2.9 × 2.7 × 1.4 cm = 1.1” × 1.1” × 0.6” Main crystal size: 1.8 × 1.1 cm = 0.7” × 0.4” Former Jan Buma collection. Number 79042

Azurite with Malachite
	ER96E5: Superb group of deep blue Azurite with hints of green where it has been converted into Malachite. The crystal is complete at the base (it is recrystallized) and the upper terminations are perfect, with no dings. Touissit, Oujda  Morocco (±1982) Specimen size: 3.7 × 1.8 × 1.1 cm = 1.5” × 0.7” × 0.4” Former Jan Buma collection. Number 82012

	Erythrite
EH96E3: Small but great. Really good color and presentation of a group of crystals that have no damage to their tips. So almost a miracle! Bou Azzer area, Ouarzazate  Morocco (±1991) Specimen size: 2.2 × 1.2 × 1.1 cm = 0.9” × 0.5” × 0.4” Main crystal size: 0.6 cm = 0.2” Former Jan Buma collection. Number 920104

Sulfur with Calcite
	JK13E8: Balanced group of crystals of Sulfur on Calcite matrix. As is so often the case with this collection it was carefully selected to provide great pleasure. Machów Mine, Tarnobzeg, Podkarpackie  Poland (±1991) Specimen size: 5.6 × 3.5 × 2.8 cm = 2.2” × 1.4” × 1.1” Main crystal size: 2.3 × 1.8 cm = 0.9” × 0.7” Former Jan Buma collection. Number 911202

	Barite
ET97E7: This has a very lively and extraordinary color. It is also special as these Barites rarely appear on the market, and when they do come from old collections (which is the case with this one – it has both Jan Buma and Geologisch Centrum de Ootmarsum, Holland labels.) Very spectacular, given its intense color. Pöhla Mine, Crottendorf, Saxony  Germany Specimen size: 6 × 3 × 4 cm = 2.4” × 1.2” × 1.6” Main crystal size: 4.8 × 2.9 cm = 1.9” × 1.1” Former Jan Buma collection. Number 921216	Front Rear

Rose Quartz
	JD46E5: Both sides are complete, and also it is soft, delicate, sweet, …. How can one describe this one? You need to hold it! Alto da Pitorra, Laranjeiras, Galiléia, Vale do Rio Doce, Minas Gerais  Brazil (±1993) Specimen size: 2.9 × 3.1 × 1.3 cm = 1.1” × 1.2” × 0.5” Main crystal size: 0.8 × 0.4 cm = 0.3” × 0.2” Former Jan Buma collection. Number 930111

	Octahedral Pyrite
JL12E3: Great brilliance and lots of color. I like the shape and I also like the fact that, while it is metallic, it does not look heavy. Quiruvilca, Distrito Quiruvilca, Departamento La Libertad  Peru (±1983) Specimen size: 6.5 × 5.9 × 3.9 cm = 2.6” × 2.3” × 1.5” Main crystal size: 3.5 × 3.2 cm = 1.4” × 1.3” Former Jan Buma collection. Number 830905

Smoky Quartz doubly terminated
	JA11E5: Intense in color, this Quartz crystal stands out from the rest of the specimen as it is doubly terminated. Moralia, Cavendish, Victoria  Australia (±1998) Specimen size: 3.8 × 3.2 × 3.2 cm = 1.5” × 1.3” × 1.3” Main crystal size: 3.4 × 2.5 cm = 1.3” × 1.0” Former Jan Buma collection. Number 980206
