T717 - Copper 'Skull' $ 1200
Keeweenaw Peninsula, Michigan, USA
cabinet - 12 x 8 x 8 cm


Copper 'Skull' from Keeweenaw Peninsula, Michigan, USA [db_pics/pics/t717a.jpg] Copper 'Skull' from Keeweenaw Peninsula, Michigan, USA [db_pics/pics/t717b.jpg] Copper 'Skull' from Keeweenaw Peninsula, Michigan, USA [db_pics/pics/t717c.jpg] Copper 'Skull' from Keeweenaw Peninsula, Michigan, USA [db_pics/pics/t717d.jpg]

Large, exceptional Copper 'Skull', a cast of Copper formed when Copper coats a rounded nodule in a conglomerate with the nodule later eroding away leaving the "skull'. This one is both good sized and exceptionally well formed (complete) and preserved. Many get smashed or dented or are only partial hemispheres. I'd say this one has about 80% coverage of what was the former nodule.

Large open vug of blue Shattuckite over Dioptase. The Dioptase formerly covered larger Calcite crystals, which are now gone, only the tips of one or two crystals can be seen on the backside now, however their form is clearly evident from the inside of the vug. The specimen is almost entirely Dioptase and Shattuckite. An unusual feature of this specimen is the light, pearly luster on the surface of the Shattuckite, which is more typically a darker, matte luster. Rare and unusual.

N'Chwanning Mine, Kuruman, South Africa
thumbnail - 2 x 1.5 x 1.4 cm

T843 - Tanzanite $ 6000
Merelani Hills, Arusha, Tanzania
miniature - 4 x 3 x 1 cm


Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/t843a.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/t843b.jpg]

Good sized pink Tanzanite crystal. Pinks are uncommon and this one is unique with a dark blue phantom line dividing the pink zone on top and a more purple/pink zone below. There is a chip on a back edge, but the termination is good and it can be display from the front undamaged. Pinks are hard to come by, but for some reason perfect undamaged pinks are even more rare, even the best known fine pink Tanzanite has a chip or two. A beautiful and uncommon Tanzanite. Weighs 21.1 grams.


T846 - Tanzanite $ 3000
Merelani Hills, Arusha, Tanzania
miniature - 4 x 2.2 x 0.7 cm


Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/t846a.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/t846b.jpg] Tanzanite from Merelani Hills, Arusha, Tanzania [db_pics/pics/t846c.jpg]

Stunning bi-color Tanzanite crystal of yellow over vivid purple/blue. This crystal has superb luster and unusually uniform shape, retaining an even 7mm thickness all the way from the base to the termination. There are two chips, including one on the back termination, but the sheer pizzaz and dramatic coloration greatly overcomes it, it's that pretty and unique. Weighs 13 grams.


T870 - Azurite $ 3500
Tsumeb, Namibia
small cabinet - 9 x 5.5 x 4.5 cm


Azurite from Tsumeb, Namibia [db_pics/pics/t870a.jpg] Azurite from Tsumeb, Namibia [db_pics/pics/t870b.jpg] Azurite from Tsumeb, Namibia [db_pics/pics/t870c.jpg] Azurite from Tsumeb, Namibia [db_pics/pics/t870d.jpg] Azurite from Tsumeb, Namibia [db_pics/pics/t870e.jpg] Azurite from Tsumeb, Namibia [db_pics/pics/t870f.jpg]

Cluster of large, partially etched Azurite crystals from Tsumeb. Fully crystallized all around, even part of the bottom is recrystallized! There is a small indentation showing Malachite on the lower front face (possibly damage, possibly natural), and the lower backside of the back crystal has some indentations/contact from another former Azurite crystal. Otherwise good all around. These good large Tsumeb Azurites are very hard to come by now.
