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

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 cm
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!

Over 4 cm in diameter, brilliantly lustrous all around and with a sharp pyramidal termination. This black tourmaline dominantly sits on a bed of smaller side-crystals and quartz of well balanced proportion. There are only minimal abrasions visible here but no actual damage. A beautiful jet-black crystal of great aesthetics!

LA15 - Opal - 460€
Khorixas, Namibia
Size: 4.4 x 2.9 x 2.3 cm
Watch Video

Found in spring 2014 this specimen is a fine example for its unique kind. The striking turquoise Paraiba-color is caused by copper and catches the eye instantly. Analysis identified this mineral as the extremely rare tridymite crystobalite opal. The opal is grown over colorless quartz as you can well see on the broken backside. The front also shows some damage but best color and the sheer rareness of this mineral more than make up for this little deficiency. Absolutely outstanding!

PB02 - Huebnerite with Quartz - 7800€

Size: 14.7 x 8.7 x 5.4 cm

Hübnerite from Peru are without question the worlds best! This stunningly beautiful specimen is agreat example for the fantastic quality the Muno Nuevo Mine produced in the recent past. Large metallic black crystals with up to 1.8 cm broad wedge shaped terminations are distributed across a rich bed of sparkling white prismatic quartz. The contrast could not be better and perfectly emphasized the single hübnerite crystals. The condition is near-perfect, some broken hübnerite are completely re-healed. An overall impressive and just marvelous specimen of world-class hübnerite on quartz!

FA249 - Malachite - 600€
Mashamba West Mine, Kolwezi District, Katanga, Democratic Republic of Congo
Size: 5.6 x 5.5 x 5.1 cm

Congo is by far the worlds best region for primary malachite. This specimen shows a rosette of interleaved lustrous forest green malachite, all very sharp and dramatic. The backside is broken or contacted but the main view is quite spectacular for the mineral and shows no considerable damage. A massive and rare primary malachite specimen of uncommon crystallization!

BL14 - Azurite - 950€
Tsumeb Mine, Otjikoto Region, Tsumeb, Namibia
Size: 5.4 x 2.6 x 2.4 cm
Watch Video

Highly unusual but staggeringly appealing, this is a perfect azurite aggreagate of high quality. At the lower parts and expecially at the side the crystal is somehow erroded but which makes for a completely unusual appearance as I have not seen alike. Some brown crumbling matrix adds more contrast to the dark, lustrous and gemmy blue azurite. There is no damage here, even the bottom is all natural. An outstanding specimen, perfect on all sides.

BK62 - descloizite with Calcite - 650€
Preguiça Mine, Sobral da Adiça, Moura, Beja District, Portugal
Size: 9 x 6.9 x 3.5 cm
Watch Video

Tiny metallic grey dipyramidal crystals of descloizite cover a colorful, red, green and yellow sceletal matrix which is elegant and stunningly beautiful alike. The fragile piece is held together by glassy white calcite of sparkling quality. A flawless, most unusual, contrasting combination piece of the rather rare descloizite with brilliant calcite.

FA238 - Cerussite - 2200€
Tsumeb Mine, Otjikoto Region, Tsumeb, Namibia
Size: 4.5 x 3.9 x 3.3 cm
Watch Video

A solid, colorless single cerussite crystal of best luster and clarity. Its shape is a characteristic sixling-twin habit. The crystal is complete all around with only minor abrasions. A smaller side-crystal is damaged but which is not apparent at all. Cerussite is definitely one of the minerals Tsumeb is most renowned for. This specimen is a fantastic example for the high quality standard set at this most famous locale. Absolutely amazing!

CM16 - Dioptase on Calcite - 1550€
Guchab-Rodgerberg area, Grootfontein District, Otjozondjupa Region, Namibia
Size: 8.8 x 7.6 x 5.5 cm
Watch Video

We all know the great dioptase specimens from Tsumeb which entered the market in the 1970s. But this specimen is much older as the enclosed label from the collector Russel Jones indicates who optained the piece in 1939, when Tsumeb was still unknown. This specimen is a beautiful small cabinet piece by any standard, no matter where it is from. It has sharp crystals to 1.2 cm smothering a matrix coated with calcite. The crystals show blueish green color and sparkling luster, nicely contrasted against the white calcite and quartz coated matrix. Some damage is undeniable but not distractive on an old classic like this!

FA125 - Vanadinite - 1100€
Mibladen, Midelt, Khenifra Province, Morocco
Size: 18.1 x 16.7 x 4.8 cm
Watch Video

This is a large plate of Vanadinite on matrix with crystals reaching well over 2 cm in diameter, over 1 cm thick. The hexagons show brigth luster and an appealing autumn-brown color with a cherry red core. The backside is completely covered in smaller vanadinite crystals but which are light brown and opaque. Some damage is present here but nothing major, even the rim is largely unharmed. A very much impressive piece with large crystals from the worlds most famous source for high class Vanadinite!

Especially the mainy pyrite on this specimen shows just excellent crystallisation and brilliant golden luster, with bevelled edges. The surface is nicely striated and shows no damage. A second pyrite has an imprint at its side but is also undamaged though the luster is not as good. Both crystals are embedded in a landscape of white quartz. Have a 360° look in our video!
