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.
Smoky Quartz (Alpine)
Cavradi, Tavetsch, Grissons
6.5 x 5.9 x 6.8 CM (cabinet)
Good Alpine Swiss Quartz has a look that is unlike any other. This has a main crystal 6 CM in size that has a warm brownish hue and is gem clear. The main crystal faces are glasslike and lustrous in close to perfect condition- only a very tiny nick as seen in the photos. The matrix is all quartz and has a few partial and complete crystals that offset the main prism nicely.
A very distinctive thumbnail with excellent crystal form that is typical of fine alpine Prehnite. Ex. Wendy Melanson's great thumbnail collection, her locale lists Cavradi Gorge Tavetsch, however it is likely that this came from Tavetsch but maybe not in Cavradi itself, but it right for that area. No matter what this is an elegant piece showing well crystallized colorless "pinwheel" forms in an attractive 3 dimensional arrangement. No damage, great luster.
Fluorite (pink and clear) on Quartz
Val Cristallina (Cristallina Valley)
4.6 x 3.4 x 1.5 CM (miniature)
A rare old piece (pre-war) from a classic alpine cleft locale, this is rather different from more recent finds. The matrix is a series of parallel quartz crystals covered with a druse of sparkling clear Flourite octahedra that are included by greenish chlorite. There are six bigger pale pink Fluorites scattered on the face, the largest 1.4 CM. Undamaged by naked eye, even at 20x magnification there is almost no damage to find. A relatively affordable and rather different Alpine Fluorite specimen.
Smoky Quartz (alpine gemmy)
Tujetsch, Vorderhien Valley
4.4X1.6 CM (miniature)
Gem clear, sharp and clean is what everyone looks for in a Swiss quartz. This is a fine small example with the lovely red brown color that makes these so distinctive. While this could be sold as a perfect example, 10x magnification and strong lighting can find some very tiny chips, so this is just "near perfect". Still an excellent small alpine crystal reasonably priced.
