This page gathers together specimens from the Jan Buma Collections that, because of their quality, rarity or interesting locality, we wish to maintain on our web site as reference specimens although they have been sold.


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.

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.

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 = 4.3” × 3.5” × 2.0”

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

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.
Jalgaon District, Maharashtra  India (±2000)

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.
Himalaya Mine, Gem Hill, Mesa Grande District, 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, Ozark-Mahoning group, Cave-in-Rock Sub-District, Hardin County, Illinois  USA (±1980)

Specimen size: 8.8 × 6 × 6.5 cm = 3.5” × 2.4” × 2.6”

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 Lake, Utah County, Utah  USA (±1996)

Specimen size: 4.4 × 3.2 × 3.6 cm = 1.7” × 1.3” × 1.4”

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

Former Jan Buma collection. Number 911202
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.
Pφhla, Schwarzenberg District, Erzgebirge, Saxony/Sachsen  Germany
