Jan Buma, apart from being a great guy, 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 of all types of worldwide minerals and then in the three key areas of his collection: Fluorite, Rumania, Indian Zeolite 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. 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 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 Zeolite and Rumanian specimens. Once again I was lucky enough to have the chance of buying the Indian Zeolite and related species collection.

To each specimen Jan added a sheet with lots of information on it that we can send to the buyer. The specimens are very commercial, appealing, and well priced, which is the really pleasing thing since Jan had a good eye when buying minerals and was buying a lot of material at a time when the prices were far lower than they are today.

THE FLUORITE COLLECTION

In 2004 Jan Buma decided to concentrate on only high quality Fluorite specimens, so he decided to sell off his Fluorites, keeping back just a select few. Jan decided to separate the Fluorites he had for sale into two groups: one that was 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 of note. We had the luck of being able to buy the second group.
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, locality, when he bought it, who he bought if from, and how much he paid. We believe that the material from this collection should be of interest to both Fluorite collectors and to those who collect a wide range of quality minerals, especially given the good quality and reasonable prices of Jan's collection.

Given the large number of specimens in the Buma's collections I could not manage them all at the same time, so I put them into stock with the aim of selling them slowly through the Internet and shows that we attend.

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

Fluorite (spinel twin) with Muscovite and Quartz

FD73H8: Color, crystallization, size… A very uncommon specimen. On the crystals, the forms of octahedron dominate but they are quite more complex than they seem, and we call attention, specially, to the existence of the spinel twin, very rare for Fluorite. The crystals are deep pink and they are on a matrix of crystallized Muscovite in which there also are some Quartz crystals. Different and unusual.

JG14J7: On the sample there are two generations of Apophyllite-(KF). The first one is formed by small and clear crystals, the second one is formed by doubly terminated and very short prismatic crystals that combine the faces of the prism with those of the dipyramid and the pinacoid so having a cubic aspect. Those crystals are practically clear but they have very evident oriented green zonation.

Apophyllite-(KF) with Stilbite

JB11F2: Very clear and brilliant crystals, most of them are doubly-terminated, and they have grown on a stalagmite of slightly blue Quartz. There are also small crystals of laminar Stilbite which are translucent and pink, and which add a special touch to the specimen.
