An exceptional Swiss alpine specimen of perfect curved rhombs in an esthetic stack. From a less well known locality at the Gauli Glacier in the Bernese alps. This zone is not well known for minerals but as the large glacier has been retreating some things have come to light. Recently (August of 2018) a heatwave uncovered a WW2 vintage US aircraft that is the second such wreck uncovered on Gauli. This Siderite is elegantly formed with a few small quartz and Rutile crystals as minor accessories. In exceptional condition and very eyecatching, this is a super Siderite from anyplace but especially choice and rare in such perfection from the Alps.
A super esthetic stack of perfect Adularia crystals in epitaxial arrangement hosting gem clear Titanites. Some selective coating of Chlorite on crystal faces of the Adulariaadds some contrast as well. This is a 360 degree piece it looks fine on all sides and has a strong esthetic arrangement. The main Titanite is 8mm perfect, gem clear flat prism with bright luster. A few tiny Quartz crystals are mixed into the matrix as well, overall a super fine arrangement of Alpine species.
Epidote -vintage, classic Swiss
5.4 x .3 x .3 CM (small cabinet/ large miniature)
A fine, vintage classic Epidote prism in perfect condition with outstanding provenance. Ex Clarence Bement, American Museum of Natural History, Jeff Glover and the Larry Conklin collections with other labels as well. The slender prism is transparent, sharp, lustrous and well terminated. This sort of Epidote is rare from Switzerland and this one (donated to AMNH in 1910) was collected well over 100 years ago. The Bement collection was at one time considered the finest ever assembled in the Americas, it later formed the heart of the AMNH collection. Bement pieces are rarely available and this Swiss Alpine specimen is a choice one. One last note there are discrepancies among the old labels regarding the location, several list Zermat as the source, but research by later collectors indicates this is a Grisons (Grischun) piece.
A very rare color and habit of Swiss Fluorite in a choice toenail. Bright red center cubo-octahedrons in a cluster of very gemmy crystals. In excellent condition and with a strong esthetic, these are nearly impossible to find on todays market. The strong red color is seen in the core of each crystal most strongly visible in the square faces. The rest of the fluorite is a light pink to colorless that allows the red core to be very visible. Choice and very attractive.
Fluorite - Pink, Alpine
6.2 x 5.2 x 2.2 CM (cabinet)
Worldwide mix summer
A cute, small classic style pink Flourite specimen with tiny but perfect octahedrons scattered on a matrix of Adularia crystals. If these were a bit bigger this would be a very expensive specimen, any good Swiss alpine Fluorite is one of the great goals in the mineral collecting world. These small crystals are choice but obviously small and so very affordable for one of these.
Prehnite crystals -Vintage Swiss
Muotta Naira, Piz Lai BlauNalps Valley, Tujetsch, Vorderrhein
11.3 x 6.4 x 2.6 CM (cabinet)
A matrix plate with clear light green Prehnite crystals to 1.4 CM scattered with smaller Prehnites and some tiny Epidote and Byssolite. Classic specimen, ex Charles Noll collection and a much older label from an unknown collection. In fine condition overall, the main crystals are pristine. Some crystals are also on the underside but the view shown is the logical display face.
Fluorite, Pink single crystal
Planggenstock, Goscheneralp, Goschenen Valley
2.1 x 1.8 x 1.4 CM (thumbnail)
new june 17
Alpine pink Fluorite with a slight zoning, frosted faces and classic habit. Mounted on a turned wooden spindle this is a nice thumbnail that wont break the bank. Not perfect, there is contacting and cleaving on the underside so this is really about the top half of the octahedron, which is the logical display side. As a result the price is far less than usual for a nice Swiss Fluorite. Excellent value
An old Swiss classic Alpine specimen. Complexly structured matrix hosts several minerals in layers with gemmy green Titanites on the top. Beds of Bysollite needles have well crystallized Adularia protruding and micro sprays of Apatite throughout. This displays the complex nature of mineralization in Alpine clefts very well. The Titanites crystals are up to 1 CM though most are smaller. Ex Charles M. Noll and Jim Dufoe collections.
