This page provides a selection of the specimens from the Jan Buma collection that have passed through the Fabre Minerals website and, due to their quality,
rarity, or significance as specimens from interesting locations, have been preserved as reference specimens in #MVM


Jan Buma, apart from being a great person, is a Dutch mineral collector who is very well known at most of the European shows since for many years he has attended them with great dedication. At these shows he bought a large number of specimens, initially all types of worldwide minerals, and then only in the three key areas of his collection: Fluorite, Rumania, Indian Zeolites and related species.

I have kept up a long friendship with Jan, which started many years ago at a Munich show. Back then I sold him one of the first specimens from the Emilio Mine, which caught his attention as it was a new locality at that time. Since then we have always kept in touch and done regular deals. So, when he sold his worldwide collection of minerals I had the opportunity and good luck of buying it. Some time later Jan decided to concentrate on an even more select range of minerals: just one, in fact - Fluorite. So he then sold his collection of Indian Zeolites and Rumanian specimens. Once again I was lucky enough to have the chance of buying his collection of Indian minerals.

THE FLUORITE COLLECTION

In 2004 Jan Buma decided to concentrate on only high quality Fluorite specimens, so he decided to sell off most of his Fluorites, keeping just a select few. Jan decided to separate the Fluorites he had for sale into two groups: ones that were easier to sell, as the specimens were relatively cheap and they were of interest because of the localities they came from; the second were the better specimens, in which the range of locations and the good quality were both noteworthy. At the end of 2010, Jan Buma, after having built yet another excellent collection of Fluorite, decided to sell his entire collection, including his best pieces.

Both the quality of the specimens, and the range of localities makes this a really interesting collection. Each specimen is very well documented, as it comes with a record on which Jan noted details of the mineral, the locality, when he bought it, who he bought if from, and how much he paid.

We hope that you enjoy these specimens from the Jan Buma Collection as much as we have enjoyed them.

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.

Fluorite on Quartz (variety amethyst)
 

FB47F7: 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.

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.

JT14F5: I find it hard to imagine how something like this formed. The center, possibly of a Quartz stalactite, has been completely covered by Fluorapophyllite-(K) crystals of various sizes. A small brown Stilbite adds to the specimen.
Nashik District (Nasik), Maharashtra  India (±2002)

Fluorapophyllite-(K) with Stilbite
 

JD86G6: Undoubtedly the most prominent aspect of the piece is its color. An intense and unusual orange color, affecting both the Fluorapophyllite-(K) and the Stilbite and contrasting with the matrix, dark in some places, white or pink in other. A very attractive ensemble.

JA66F2: Most of the crystals of Fluorapophyllite-(K) are doubly terminated, formed from a prism and very sharp pyramids. The brilliance and transparency are very intense and the crystals of pink Stilbite seem to soften the esthetics, giving balance to the specimen.
Jalgaon District, Maharashtra  India (±1996)

Specimen size: 13 × 8 × 4.5 cm = 5.12” × 3.15” × 1.77”

Fluorapophyllite-(K) with Julgoldite-Fe inclusions
 

JE89E5: Yes, this is an exceptional specimen! The inclusions of Julgoldite-Fe that dye the crystals of Fluorapophyllite-(K) 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.

Fluorapophyllite-(K) 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, Fluorapophyllite-(K), 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 = 5.71” × 3.74” × 2.36”

JB68E7: This one deserves a good description. The crystals of Fluorapophyllite-(K) 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 = 4.33” × 3.54” × 2.05”

Fluorapophyllite-(K) 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.
The specimen has been reviewed, photographed and published in the magazine ‘Mineral Up’ on page 65 in number 2011/1
Jalgaon District, Maharashtra  India (±2000)

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, Wagholi, Pune District (Poonah District), Maharashtra  India (±2001)

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 Fluorapophyllite-(K) and white Stilbite. On the rear the areas of exfoliation do not affect the esthetics of the specimen.

Scolecite with Fluorapophyllite-(K)
 

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 Fluorapophyllite-(K), suspended on a bundle of Scolecite as if by magic, is the final touch to this work of art.

Julgoldite-(Fe) with Fluorapophyllite-(K)
 

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 Fluorapophyllite-(K), which are doubly-terminated, brilliant, water clear and with sharp pyramids.

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, Bunker Hill properties, Kellogg, Coeur d'Alene District, Shoshone County, Idaho  USA (±1995)

Baryte
 

ET97E7: This has a very lively and extraordinary color. It is also special as these Barytes 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.
