OK24 - Adularia with Chlorite on Quartz - Sold
Keilbachtal, Ahrntal, Bozen, South Tyrol, Italy
Size: 4.7 x 3.9 x 3 cm
Watch Video
 
 
 

Almost like a mushroom head, the adularia is clustered atop a transparent, prismatic quartz crystal. The adularia is covered in a thick layer of green chlorite leaving only the shape to let us know what's underneath. Still, at some spots the white color of the adularia breaches the dark green crust. While the quartz is broken at the bottom and backside - which is not visible from the front - the adularia is almost perfect with only a couple of small spots of damage at the backside. A great and highly unusual specimen of outstanding aesthetics!


WA22 - Pyrite ps. Pyrrhotite - Sold
Stari Trg Mine, Trepca complex, Trepca valley, Kosovska Mitrovica, Kosovo
Size: 12.9 x 12 x 10 cm
Watch Video
 
 
 

A classic piece from this old mineral deposit that strikes with a unusually rich paragenesis. The front view immediately focuses on a hexagonal shape of pyrite. In fact this obviously is a large pyrrhotite crystal that has been pseudomorph transformed to or maybe just overgrown by hundreds of golden pyrite crystals. Further to the back there is a crown-like formation of white calcite and pink rhodochrosite adding nice color and shape. The base of this impressive piece is of massive galena, partly overgrown with fine quartz needles and even, at closer inspection, some gypsum. Large and heavy yet vibrant and full of pretty details!

This is a cluster of interlocked sharp metallic tetrahedrite in association with pyrite. The largest tetrahedrite is 2.9 cm on edge. The cluster sits on some golden shining pyrite. The backside is largely broken but the main view is in excellent condition. A characteristic paragenesis from the Mundo Nuevo Mine with dominant tetrahedrite crystals of considerable size!

Very nice and well balanced association of white quartz and bright golden chalcopyrite. This whole sweeping landscape is in very best condition and utterly appealing all over!

The piece is out of a new find and it is 100% lovely. It is incredibly aesthetic with a cluster of rich pink fluorapatite on a perfectly contrasting white albite matrix. The apatite is highly lustrous, sharp and shows unusual crystal habit. The piece is complete all around, with contacts at the bottom but no damage. Small edgewear is present but not apparent. Definitely a marvelous piece, very elegant and with no downsides. A real jewel!


UP4 - Titanite - Sold
Kristallwand, Frosnitztal, East Tyrol, Austria
Size: 4.1 x 3.9 x 2 cm
Watch Video
 
 
 

An excellent, sharp and gemmy single titanite crystal of brown color is prominently situated on a sparkling piece of white and grey matrix. The crystal is flawless and of very best quality! Brown titanite from the Alps is by far more rare than the green variety and especially when it comes to this kind of outstanding quality, the air is getting VERY thin! Perfect aesthetics meets best crystal quality!


IX32 - Quartz Gwindel - Sold
Val Giuv, Tujetsch, Vorderrhein Valley, Graubünden, Switzerland
Size: 2.6 x 1.1 x 0.6 cm

An excellent closed gwindel, surprisingly long and with a very distinct twist. The slender shape of this thumbnail specimen makes it very much unusual and exceedingly rare. There is just one minimal ding at the side but otherwise no damage. The crystal is clear with a lustrous surface that ist smooth at the front and slightly chloritized at the back as you can very well see in our video. An absolutely remarkable piece of unique shape!Seidenmatte Oberfläche


ZH5 - Fluorite - Sold

The octahedral fluorite aggregate on this matrix specimen is a staggering 4.6 cm in total, shows intensively pink color and is beautifully developed. The white feldspar matrix provides stark contrast in perfect proportion. I can't remember seeing any specimen from Zinggenstock of such exceptional dimension, especially in such flawless condition! Absolutely spectacular in person!


KI4 - Liddicoatite with Albite - Sold
Antsira Mine, Sahatany Valley, Vakinankaratra Region, Antananarivo Province, Madagascar
Size: 4.1 x 3 x 1.4 cm

Wonderfully aesthetic and of best tourmaline quality, this is a beautiful and very well balanced specimen of liddicoatite with contrasting white albite. The single crystal is sharp and well defined with a flat, superbly lustrous termination. The whole piece is in best condition with some contact but no real damage - a small chip at the back is not fresh but re-healed. Give it some backlight and the intense pink color of the top zone is unbeatable! Lower down, the color changes to olive green and brick red at the bottom, all very much transparent and striking. A brilliant miniature of excellent aesthetics!

This thumbnail hematite specimen is absolutely brilliant on both sides and completely free of damage! The lovely developed rosette of stacked hematite plates forms a sparkling miracle of utter beauty! The bottom is contacted but not broken!
Atop the front face you can find some small quartz crystals which add a little more live to this specimen. Absolutely gorgeous in person!


WZ38 - Smoky Quartz - Sold
Val Giuv, Tujetsch, Vorderrhein Valley, Graubünden, Switzerland
Size: 9.9 x 5 x 4.5 cm
Watch Video
 
 
 

The center of attention is a prominent single smoky quartz crystal of finest quality! Warm color throughout the whole gemmy clear crystal, sharp edges and no flaws at all. It is distinctly right-handed (as is the smaller side crystal) and shows a beginning termination at the bottom, where it then merges into a flat matrix of adularia, small smoky quartz and even epidote and some byssolite. Very attractive and highly aesthetic as the main crystal is incredibly dominant here and fully lives up to his role. Have a look on our video for a better 3-dimensional look!


UP8 - Quartz Phantom - Sold
Val Gronda da Cavrein, Vorderrheintal, Graubünden, Switzerland
Size: 11.5 x 7.6 x 4.5 cm

This is not quite the usual specimen from Cavrein valley but a distinctive phantom quartz on matrix! The main crystal is 5.1 cm long, colorless and transparent. At the center it displays a very sharp brownish phantom as a shadow of the former crystal that has later grown further to the current size. The main crystal is accompanied by smaller quartz which show the same kind of phantom inside. They are all grown on a natural grey rock matrix with a crust of microscopic feldspar. The tip of the main crystal is a bit rough but which is contact induced, not damaged. Very nice and unusual specimen in best condition!
