SK06 - Fluorite and Quartz - 7000€
Yaogangxian Mine, Yizhang Co., Chenzhou Prefecture, Hunan Province, China
Size: 10.6 x 8 x 6.5
Watch Video
 
 
 

An unusually aesthetic paragenesis of quartz and fluorite, associated by some smaller, sharp arsenopyrite crystals on a dark muscovite matrix. Most dominant are two brilliant quartz crystals at the back which oppose a single purple fluorite cube. The quartz is clear, shows excellent luster and a very distinctive and attractive phantom. The fluorite is of similarly high quality, clear and of nice purple color. Some edges show very minimal wear and there is a contact on the muscovite but there is no actual damage to report. An outstanding piece of high quality and superb composition from Yaogangxian, one of Chinas richest mineral deposits!


MN22 - Kunzite - 900€
Laghman Province, Nuristan , Afghanistan
Size: 17.8 x 3.6 x 2.6

An impressive 17.8 cm kunzite of great translucent quality that shows no damage anywhere. Even the bottom is completely re-crystallized. The crystals pink color is especially concentrated along its c-axis, meaning that an illumination from the bottom brings out the vivid candy-pink this mineral is famous for. Attached to the side face you find a dark red tantalite-(Mn) around 1.7 cm across. The overall quality of this specimen is good yet not great but size, color and condition make up for a lot here!


MN19 - Galena - 750€
Sweetwater Mine, Missouri, USA
Size: 11.8 x 9.1 x 8.8

2.1 kg of solid galena, brilliantly crystallized on all sides, even at the bottom which makes this a perfect floater. The Sweetwater Mine in the Viburnum Trend - the belt of lead mines in Missouri - is well known for its world class galena specimens. Especially nice about this specimen is the 3-dimensional shape of intergrown cubical crystals that are heavily modified to show hundreds of faces. The luster is not top but good all the same. At close inspection you will find some nice little sphalerite distributed about the galenas surface. This whole specimen is free of damage, full of lovely details and a real stunner in person!


FA292 - Fluorite - 850€
Okorusu Mine, Otjiwarongo District, Otjozondjupa Region, Namibia
Size: 10.8 x 7.9 x 4.5
Watch Video
 
 
 

Large cuboctahedral fluorite crystals of fantastically bright green color and great luster are stacked upon each other to shape this brilliant piece. The periphery is contacted but not broken or otherwise damaged. Okorusu fluorite is nealry always crystallized as straight cubes, which makes this combination shape of cube and octahedron most unusual and rare. Still, what most dramatically impresses at this piece is the rich emerald green color that glows inside this specimen. Sure, it needs some direct backlight, but when provided this is a real stunner!


PB114 - Pyrite - 750€
Huanzala Mine, Huallanca District, Dos de Mayo Province, Peru
Size: 10.7 x 7.7 x 4.5

Shiny like a disco ball and perfectly developed on all sides, this is a superb pyrite floater of best quality. While the frontside has the larger crystals - the cubes are up to 1.5 cm on edge - the backside is more delicate, nested and shows beautiful striations. Aside of some very minor edgewear this piece is in excellent condition, very attractive and sculptural in person!


PB170 - Barite - 350€
Huánuco Department, Peru
Size: 5.7 x 5.1 x 4.2
Watch Video
 
 
 

Several panels of glassy, smoky yellow barite are prominently stacked on a pink dolomite matrix. The largest crystal is around 3.5 cm long, shows best luster and a sharp, distinct shape. All crystals are flawless and 3-dimensionally arranged to form this highly aesthetic specimen!


PB132 - Barite - 1500€
Cerro Warihuyn, Miraflores, Huamalíes Province, Huánuco Department, Peru
Size: 12.3 x 9.6 x 5.5

Thick and well defined tabular barite of honey yellow color on a dark brown matrix. The barite is 3-dimensionally arranged on the matrix with the largest crystal - 4.7 cm on edge and 0.9 cm thick - nicely standing out and presenting itself. All crystals show best luster and are perfectly gemmy. There is some edgewear scattered across this piece but most of which is old and rehealed. Sheer size, color and quality are a stunning combination on this rich and impressive specimen!


FA303 - Dioptase on Calcite - 850€
Tsumeb Mine, Otjikoto Region, Tsumeb, Namibia
Size: 15.2 x 8.3 x 3.4
Watch Video
 
 
 

Like green icing on white sugar cubes, the dioptase forms a coating of microcrystals over white calcite. The rhombohedral calcite up to 0.8 cm on edge are evenly distributed about a grey matrix, the green dioptase has settled on it like snow, covering only the left upper faces. An absolutely lovely piece of light green and white color that's sparkling with hundreds and thousands of tiny crystals!


RK353 - Enargite - 1600€
Huanzala Mine, Dos de Mayo Province, Huánuco Department, Peru
Size: 5.5 x 3.8 x 2.7

Enargite is a rare species, particularly for the Huanzala Mine which is best known for its superb pyrite specimens and great fluorite. The short prismatic crystals are of metallic grey color with some rust brown coating and minimal weathering. Between the enargite is some pyrite, sparkling golden microcrystals. The overall aesthetics of this rare specimen is just great with no visible damage anywhere!


SO102 - Fluorite - 2200€
Annaberg, Erzgebirge, Saxony, Germany
Size: 5.5 x 4.7 x 2.7
Watch Video
 
 
 

The unusual color combination of this aesthetic fluorite specimen is quite intriguing especially when lit from the back which brings out the intensive purple phantoms that rest inside these honey-yellow fluorite cubes. This is a formation of several stacked cubes of fine translucent quality. The sides are contacted but not broken. The bottom is re-healed. There is one single chip at the larger crystal but which does not distract from the great visual impact of this piece. At the faces of the fluorite you will find tiny metallic grains, presumably chalcopyrite. Remarkable crystal size, appealing composition and stunning colors are combined to this amazing and exceptional piece.


PB194 - Atacamite - 950€
Lily Mine, Pisco Umay, Ica Department, Peru
Size: 4.5 x 3.5 x 2.1

Bad news first: this crystal is repaired. But honestly, some pieces are worth repairing and this large single crystal of doubly terminated, dark green and lustrous atacamite on matrix is definitely one of those. Atacamite from the Lily Mine usually comes as acicular crystals, often non-terminated and enclosed in gypsum. This piece is exceptionally well developed. The main crystal is impressive 3 cm long, has a sharp bladed termination and sits perfectly aesthetic in the centre of a sparkling quartz covered matrix. Definitely a significant piece for this locale!significant


FA254 - Fluorite on Sphalerite - 650€
Naica, Mun. de Saucillo, Chihuahua, Mexico
Size: 8 x 5.8 x 4
Watch Video
 
 
 

This is a classic piece for Naica, with the characteristic modified, beveled cubical crystals on a contrasting black sphalerite matrix and some chalcopyrite at the backside. The crystals are nicely stacked upon each other with increasing diameter to the top. The color is pale inside the transparent crystals, yet shows a surprising change from a green tinge - visible closer to the matrix - to a light purple. Condition is well with only some very minor issues, nothing to worry about. A cluster of amazing aesthetics and high quality!
