T656 - Rosasite after Malachite after Azurite (R) $ 3500
Tsumeb, Namibia
cabinet - 10 x 9 x 7 cm


Rosasite after Malachite after Azurite (R) from Tsumeb, Namibia [db_pics/pics/t656a.jpg] Rosasite after Malachite after Azurite (R) from Tsumeb, Namibia [db_pics/pics/t656b.jpg] Rosasite after Malachite after Azurite (R) from Tsumeb, Namibia [db_pics/pics/t656c.jpg] Rosasite after Malachite after Azurite (R) from Tsumeb, Namibia [db_pics/pics/t656d.jpg]

Rare large cluster of Rosasite after Malachite after Azurite crystals, the largest cluster I can recall ever seeing. Note that this has been repaired in a number of places. This came out of an old collection and the repairs have not been done to modern standards, so it could be greatly improved. There are five large crystals that comprise the group. Just a rare and spectacular piece.


T657 - Malachite on Chrysocolla after Malachite $ 1200
Katanga, Congo
cabinet - 10 x 8.5 x 4 cm


Malachite on Chrysocolla after Malachite from Katanga, Congo [db_pics/pics/t657a.jpg] Malachite on Chrysocolla after Malachite from Katanga, Congo [db_pics/pics/t657b.jpg] Malachite on Chrysocolla after Malachite from Katanga, Congo [db_pics/pics/t657c.jpg]

The Katanga region of the Democratic Republic of Congo is the Malachite capital of the world, yet most found is lapidary grade with only a small percentage (usually fibrous or stalactitc specimens) being of any interest to mineral collectors. With specimens like this, Katanga can also claim to be one of the best localities for perfectly crystallized Malachite too. This specimen features perfectly formed individual crystals to 1.3 cm on a colorful and contrasting matrix of sky blue Chrysocolla. Just fabulously sharp single crystals.The Chrysocolla has partially psuedomorphed an earlier generation of Malachite crystals.


T658 - Chalcocite $ 420
Kipushi Mine, Katanga, Congo
miniature - 4.5 x 3.6 x 2 cm


Chalcocite from Kipushi Mine, Katanga, Congo [db_pics/pics/t658a.jpg] Chalcocite from Kipushi Mine, Katanga, Congo [db_pics/pics/t658b.jpg] Chalcocite from Kipushi Mine, Katanga, Congo [db_pics/pics/t658c.jpg]

Large, complete single crystal. Well crystallized on both sides and shows good iridescence. This is old material from the collection of longtime African dealer Rob Smith. If you search Mindat photos for the locality, all you will find are millimeter sized crystals.


T659 - Tarnowitzite $ 600 SOLD
Tsumeb, Namibia
cabinet - 13 x 9 x 6.5 cm


Tarnowitzite from Tsumeb, Namibia [db_pics/pics/t659a.jpg] Tarnowitzite from Tsumeb, Namibia [db_pics/pics/t659b.jpg] Tarnowitzite from Tsumeb, Namibia [db_pics/pics/t659c.jpg] Tarnowitzite from Tsumeb, Namibia [db_pics/pics/t659d.jpg] Tarnowitzite from Tsumeb, Namibia [db_pics/pics/t659e.jpg]

Large matrix specimen loaded with gemmy Tarnowitzite crystals. The matrix is coated by micro crystals giving a sugary luster, and some of the larger crystals have red areas of inclusions. In excellent condition overall as I could only find a couple missing crystals. Good on both sides.


T660 - Sugilite $ 2500
N'Chwanning III Mine, Kalahari Manganese Fields, South Africa
small cabinet - 5.3 x 4 x 2 cm


Sugilite from N'Chwanning III Mine, Kalahari Manganese Fields, South Africa [db_pics/pics/t660a.jpg] Sugilite from N'Chwanning III Mine, Kalahari Manganese Fields, South Africa [db_pics/pics/t660b.jpg]

Wow - shocking new material here. Prized Sugilite specimens were first those with small crystals, then later came the specimens with fibrous crystals. And now this style, the first I've ever seen like it. This is a solid seam of fibrous, chatoyant Sugilite, the best (though not the biggest) out of only 5 pieces available. A rare and unusual specimen, but could you imagine cat's-eye Sugilite cabachons? Weighs 55.6 grams.


T661 - Chalcotrichite in Calcite with Malachite $ 2500 SOLD
Tsumeb, Namibia
small cabinet - 7 x 6 x 5 cm

Two generations of Calcite with the later generation showing incredible orange coloration due to inclusions of Chalcotrichite. To add to the color explosion are fibrous bright green crystals of Malachite. Peeking out in areas is the first generation of Calcite, which is green due to inclusions of Dioptase This is old material from the collection of longtime African dealer Rob Smith. Sawcut on one side.

Unique thumbnail specimen of star-shaped Mimetite with attached Malachite. Fully crystallized all around with only one tiny point of contact on the backside.
