Furce Pass, Canton Uri, Switzerland
Thumbnail, 2.6 x 2.6 x 2.3 cm
A rare locality piece from historic collecting in this location and part of Ernie Schlicter's alpine suite. This is a superb, lustrous single crystal, complete all around except only a small contact to matrix in the lower back. I bought this and some other pieces in this update from the collection of Ernie Schlicter back around 2007, before the whole collection was sold, and held it till now.
This rare highly desirable locality unique distinct style Two pastel
Ziggenstock, Grimsel, Bern, Switzerland
Miniature, 4.9 x 3.0 x 3.0 cm
This is from a rare and highly desirable locality, with unique and distinct style. Two, pastel pink, gemmy, heavily modified fluorite crystals to 1.5 cm across are aesthetically perched on lustrous, sugary adularia, a variety of orthoclase. Although not as deeply colored as some of its alpine cousins, the transparency and complexity of the crystals is absolutely superb. This pocket, or this style rather from this region, is notable for its difference from the common sort of Alpine fluorite. I have seen such pieces at Munich for twice the price, in Euros yet, as they seem overly valued to me in the European market.

Massif de l
Cabinet, 10.4 x 7.2 x 4.1 cm
This specimen if from a find of fall 2008, which has really shocked the French fluorite collectors that I know, and is the kind of rare locality find that impresses outsiders as well. The color, luster, and transparency of these crystals is above average for Chamonix, more of a vibrant pink-red than the usual muted pink hues we have seen in most pockets of these rare Alpine fluorites. This specimen has crystals to 4.25 cm, perched on a slender shard of white, crystallized adularia (feldspar) matrix. It is a stunning association, and contrast. The crystals here climb up the shard, one atop the other. Note how gemmy and translucent the top crystal is. It has a termination that is complete all around, 360 degrees. The piece itself, actually, is ALSO complete all around the backside, if somewhat roughly crystallized compared to the front. The point is, though, that the crystals all wrap around and have sharp edges as well. In person, this has better luster than in the photos - it seems very hard to convey accurately. It has been since 1998 and the Pt Kurtz pocket that a single find of pink/red fluorite from the Alps has gotten so much attention and produced a new, unprecedented quality. This does not happen, thus, very often. Few good specimens were available, under several dozen.
This classic alpine style specimen large fist sized cluster gemmy
Vizze Valley (Pfitsch Valley), Bolzano Province (South Tyrol), Trentino-Alto Adige, Italy
Cabinet, 10.1 x 9.5 x 6.0 cm
This is a classic alpine style specimen: a large, fist-sized cluster of gemmy, translucent orthoclase feldspar crystals. The cluster is a floater, complete all around. It is unusually pristine and sharp, and very 3-dimensional in person. The photos show it in normal frontal lighting, though it has a better "glow" to it when backlit. Impressive, in person! From the collection of Hubert De Monmonier (1919-2007), donated by bequest to the University of Arizona Museum to add to their displays and to provide specimens for sale to establish an endowment fund for museum operations, in perpetuity.
