From the type locality, this is an extremely rare gem floater crystal of axinite-(Mg) (magnesioaxinite). The crystal is color-zoned from clear to pale salmon, has a superb vitreous luster, and has a sharp form. It fluoresces red to violet under LW UV. Figured in the Merelani issue of the Mineralogical Record. 3.3 x 2.2 x 0.5 cm.

Large, beautiful pseudomorph of malachite after azurite from Onganja. The malachite is well crystallized in velvety sprays, as can be seen in the close-up. The large crystal at the top is 6.0 cm long. 6.9 x 6.9 x 5.6 cm.

Africa103 - Cobaltoan Calcite with Heterogenite - Musonoi Mine, Kolwezi, Katanga, Democratic Republic of the Congo

Superb, brightly colored specimen from the best locality (in my opinion) for cobaltoan calcite. The dark heterogenite and white calcite provide an excellent color contrast. 5.1 x 4.4 x 2.8 cm.

Africa104 - Phenakite and Siderite - Klein Spitzkopje, Spitzkopje Area, Karibib District, Erongo Region, Namibia

Very rich specimen of intergrown, doubly-terminated, colorless crystals of phenakite to 7 mm. Also present are lenticular crystals of somewhat corroded siderite crystals. The right side of the reverse is covered with small cubic crystals of a brownish mineral which is highly fluorescent yellow under both SW and LW UV; this may be florencite-(Ce) but it has not been tested. Ex. Pough and Feinglos collections with labels. 7.7 x 4.8 x 2.0 cm.

Africa105 - Carrollite on Calcite - Kamoya South II Mine, Kambove, Katanga, Democratic Republic of Congo

Nice 1.2 cm, complex, lustrous crystal of this rare sulfide mineral. The additional smaller crystals are mostly quite nice as well, although there is some scattered contacts and minor damage as shown in the photos. 7.7 x 6.7 x 5.0 cm.

Africa106 - Smithsonite and Willemite - Berg Aukas, Grootfontein District, Otjozondjupa Region, Namibia

Good specimen of pale yellow smithsonite and salmon-colored willemite from Berg Aukas. The smithsonite has the "wheat sheaf" crystal form common from this locality, some of which are doubly-terminated, and measures to 2.6 cm. The willemite is fluorescent. Better in person - it was difficult to photograph due to the low contrast of the smithsonite crystals. 6.2 x 5.1 x 2.2 cm.

Africa111 - Cuprite on Chrysocolla - Dikuluwe Mine, Kolwezi, Western Area, Katanga Copper Crescent, Katanga, Democratic Republic of Congo

Red, lustrous, translucent doubly-terminated cuprite crystals to 1.1 cm are on blue-green chrysocolla. Most crystals, including the largest, are in excellent shape. The Dikuluwe Mine is west of the better known Mashamba West Mine and specimens from here are less common. 8.4 x 8.0 x 3.6 cm.

Africa112 - Cuprite on Chrysocolla with Malachite - Mashamba West Mine, Kolwezi District, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre)

The light blue chrysocolla of this specimen provides an excellent contrast to highly lustrous, red cuprite crystals which measure to 1.2 cm. There is also some bright green sprays of primary malachite present; the sprays measure to about 6 mm. I believe the brown crystals present are baryte. 4.5 x 3.3 x 2.9 cm.
