A small, doubly terminated Liddicoatite crystals of amazing color-play. The crystal does not need much light to reveal its intense colors that range from apple green to a juicy raspberry red and some yellow patches.

A lovely adularia floater that's overgrown with hematite, forming a very well developed and lustrous iron rose. The combination of adularia and hematite is quite characteristic for Fibbia although the tightness of this connection is unusual. With no damage and very good quality this is a most desirable little piece!

GM18 - Quartz - Sold

Size: 9 x 5.8 x 4.3 cm

It's a very nice floater specimen of completely colorless, transparent quartz. Around the base there is some silvery chlorite over quartz which adds contrast. The backside of the main quartz is intergrown with chlorite as well but still very well defined. The tip is somewhat rough with edge-wear but the overall condition is very good with no actual damage.


GM31 - Fluorite - Sold
Kleines Furkahorn, Furka pass area, Goms, Wallis, Switzerland
Size: 5.7 x 4.7 x 3.3 cm
Watch Video
 
 
 

Rich pink color dramatically radiates from this single crystal fluorite even at roomlight but is spectacularly amplified at direct backlight. A fascinating crystal in person that is completely clear at the inside with a flawless silky surface all around. At the lower right you see the imprint of another crystal. The backside is slightly etched and has an organic look. Unlike famous Swiss fluorite sources like Frunthorn or the Gotthard massif, the Furkahorn only produced few pieces of importance. The dramatic size and quality of this very specimen absolutely stand out!


RK441 - Rubellite - Sold
Paprok, Nuristan Province, Afghanistan
Size: 5.7 x 4.1 x 2.8 cm
Watch Video
 
 
 

This rubellite aggregate shows just lovely pink color, combined with some white cleavelandite in between. The tourmaline itself is unusual as most parts are just plain pink with flat terminations but a smaller patch in the middle shows a distinct yellow-green and much more complex termination. All main crystals are in perfect condition. Only some smaller side crystals, somewhat unfortunately located at the lower front, are broken, which much reduces the price on this otherwise brilliant piece.

It's hard to ever find a thumbnail gold specimen of such perfect aesthetics and quality! The gold crystals, sitting on a well proportioned marvelous white calcite matrix, are extremely lustrous and sharp. A picturesque little stunner of highest Eagle's Nest quality!

Oberndorf is the source of the worlds best strontianite crystals and this specimen is an impressive and brilliant example for the size and quality this mine produces! The heavy, snow white matrix nicely emphasizes the pale toe intensively orange strontianite crystals that come in ball-like clusters up to around 3.5 cm in diameter. The strontianite is all translucent and in very good condition. There is some damage present but which fades on a fantastic and exceedingly rare piece like this! A real Alpine classic in best natural shape!

Bright Red-Cloud-quality immediately leaps to the eye at this small but impressive specimen! The wulfenite shows absolute best quality with striking orange color and incredible luster all around!

AT70 - Tetrahedrite on Quartz - Sold
Mundo Nuevo Mine, Mundo Nuevo, Huamachuco, Sanchez Carrion, La Libertad, Peru
Size: 6.3 x 5.5 x 3.3 cm

A relatively large and sharp tetrahedrite cluster sits in the middle of a nice spray of white quartz crystal. The coronal shape reminds me of some cristmas decoration that beautifully centers on the main attraction, the metallic tetrahedrite. The crystals are largely intact, only small abrasions are to be found at closer inspection. The surface has a thin grey coating that covers the otherwise mirroring tetrahedrite. A rare specimen of very catchy, 3-dimensional composition!
