TXQ-PCQBeryl : Be3Al2(Si6O18), Muscovite : KAl2(AlSi3O10)(OH)2

Multiple photos available
Shigar Valley, Skardu District, Baltistan, Gilgit-Baltistan, Pakistan

Dimensions: 100 mm x 88 mm x 76 mm
Largest Crystal Size: 38 mm
Weight: 448 g

Pale blue transparent beryl crystal, with the usual hexagonal prismatic habit and a complex termination showing at least ten faces. Surrounded by a number of large hexagonal crystals of muscovite. A minor beryl cristal near the right bottom, contacted on the tip. All covering a white compact feldspar matrix. Overall size: 100mm x 88mm x 76mm; main beryl crystal: 38mm tall (visible part) and 20mm wide. Mass: 448g. No damage can be seen with my naked eye and I guess neither with a magnifying glass. The main beryl crystal is perfect and complete 360º.

TUV-9HGManganite : Mn3+O(OH)

Multiple photos available
Ilfeld, Nordhausen, Harz, Thuringia, Germany

Dimensions: 110 mm x 54 mm x 39 mm
Largest Crystal Size: 18 mm
Weight: 347 g

Very bright and lustrous, well formed, jet-black prismatic crystals of manganite. The plate has dozens of sharp columns up to 18 mm tall, striated according to the c-axis with the typical rough flat terminations, densely covering the top of an 110 mm x 54 mm x 39 mm massive manganite matrix. Weight: 347 g. I can't see any damage with my naked eye except in the periphery. An old-time European classic from the type locality that set the standard for the species (and still does). Put on sale in the XIX century by the German dealer Dr. Adam August Krantz (1808-1872), as seen in the label that comes with it. He was then one of the foremost mineral dealers in Europe, established in Bonn from 1850 until his death. Wikipedia: https://en.wikipedia.org/wiki/Adam_August_Krantz

97Y-MQJTetrahedrite : Cu6[Cu4(Fe,Zn)2]Sb4S13, Hübnerite : MnWO4, Quartz : SiO2

Multiple photos available
Mundo Nuevo Mine, Mundo Nuevo, Huamachuco, Sanchez Carrion Province, La Libertad Department, Peru

Dimensions: 92 mm x 61 mm
Largest Crystal Size: 25 mm
Weight: 137 g

A crowd of metallic tetrahedrite crystals, the biggest of which is 25 mm on edge, is perched on a large cluster of colorless quartz crystals. The major of these is 86 mm tall, and they are mostly transparent with a somewhat frosted surface making it translucent white. As a little surprise a hübnerite crystal can be spotted just at the geometrical center of the photo, partly overlapping the white main quartz. It is 17 mm long and 7.5 mm wide, and is embedded between quartz and tetrahedrite. When backlit in the right way it shows the typical deep red color. The whole specimen weighs 137 g and measures 92 mm x 61 mm.

WKU-9N7Quartz : SiO2, Epidote : {Ca2}{Al2Fe3+}(Si2O7)(SiO4)O(OH)

Mun. Las Vigas de Ramírez, Veracruz, Mexico

Dimensions: 111 mm x 91 mm
Largest Crystal Size: 53 mm
Weight: 297 g

Group of purple to colorless transparent quartz crystals on a matrix covered by contrasting small acicular green epidote. Overall size: 111mm x 91mm. Widest crystal: 14mm. Tallest crystal: 53mm. Weight: 297g. Since I stand against the use of varieties I much prefer not to name it amethyst. Simply quartz.

KPF-3YFAegirine : NaFe3+Si2O6, Orthoclase : K(AlSi3O8), Zircon : Zr(SiO4)

Mount Malosa, Zomba District, Malawi

Dimensions: 108 mm x 51 mm
Largest Crystal Size: 92 mm
Weight: 124 g

Group of black color aegirine crystals with acute edges, showing very lustrous almost mirror-like faces and a rather uncommon (in this locality) sharp pointed habit. Several crystals of colorless orthoclase accompany them on the base and a small zircon crystal can be seen on the back side. Overall size: 108mm x 51mm. Main aegirine crystal: 12mm wide, 92mm tall. Weight: 124g.

Huayllapon Mine, Pasto Bueno, Pampas District, Pallasca Province, Ancash Department, Peru

Dimensions: 108 mm x 67 mm
Largest Crystal Size: 63 mm
Weight: 351 g

Association of parallel hübnerite crystals with colorless quartz. Deep red color when backlit (indicating a predominance of manganese on iron in the hübnerite-ferberite series). Overall size: 108mm x 67mm. Main hübnerite crystal: 63mm tall, 26mm wide. Main quartz crystal: 72mm tall, 21mm wide. Weight: 351g.

V89-PJGPyrite : FeS2, Quartz : SiO2

Multiple photos available
Huanzala Mine, Huallanca, Huallanca District, Bolognesi Province, Ancash Department, Peru

Dimensions: 102 mm x 70 mm x 40 mm
Largest Crystal Size: 53 mm
Weight: 314 g

Group with several octahedral {111} pyrite crystals on a bed of colorless quartz, a typical specimen of that prolific and already classic mine. The main crystal is complete all around, measures 53 mm from tip to tip and 41 mm on edge, with narrow stepped edges that may be faces of rhombododecahedron {110}. The octahedral faces are mirror-like, as can be appreciated with the reflected quartz crystals. In very good condition except for some natural but stabilized cracks (hard to see in the photos). Overall size: 102 mm x 70 mm x 40 mm. Weight: 314 g.

LRC-AA3Sphalerite : ZnS, Dolomite : CaMg(CO3)2, Calcite : CaCO3

Multiple photos available
Trepča Stan Terg Mine, Trepča complex, Trepča valley, Kosovska Mitrovica, District of Kosovska Mitrovica, Kosovo

Dimensions: 124 mm x 87 mm x 39 mm
Largest Crystal Size: 29 mm
Weight: 471 g

Association of black highly lustrous sphalerite crystals showing very sharp edges and well defined mirror-like faces, which is not typical of the species, partially covered with smaller colorless crystals of dolomite and calcite that produce a deep and nice contrast. The specimen has been kept by a local miner in pristine condition, free of any damage, since its extraction some time between years 1994-2002. Contains several spinel-law twins on the octahedral {111} face as can easily be appreciated in the photos. Overall size: 124 mm x 87 mm x 39 mm. Major crystal size: 29 mm on edge. Weight: 471 g. Unfortunately this is a not photography friendly specimen.
