Braunite : Mn2+Mn3+6[O8|SiO4] | |
|
|
Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa 1.7 x 1.6 x 1.1 cm. A super thumbnail of competition quality for the species, featuring 2 large crystals that are doubly-terminated and 1 cm across, perched diagonally in a cluster with smaller crystals. This specimen perhaps best shows the odd modified form of these new braunites. |

Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa 5.5 x 4.6 x 2.3 cm. A very rich specimen with these sharp new braunites (to 4 mm), of incredible lustre and brightness, surrounding sharp bixbyite crystals to 6mm. |

Braunite : Mn2+Mn3+6[O8|SiO4] | |
|
|
Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa 5.0 x 3.6 x 1.8 cm. A brilliantly lustrous, sparkling-metallic plate composed of solid braunite on which are perched a half dozen shockingly sharp and lustrous larger crystals of braunite. The complex form of these crystals is novel, and they had to be analyzed to find out their identity (per Charlie Key, pers. comm.). |

Braunite : Mn2+Mn3+6[O8|SiO4] | |
|
|
Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa 4.0 x 3.2 x 1.7 cm. A sharp, isolated 8mm crystal, that is complete all around and doubly-terminated, is the highlight of this specimen. The crystal is sharp and super lustrous, quite unlike previous finds here. The crystal sits on matrix of sparkling microcrystallized braunite. |

Wessels Mine (Wessel's Mine), Hotazel, Kalahari manganese fields, Northern Cape Province, South Africa 6.3 x 5.3 x 4.1 cm. This large matrix specimen hosts brilliantly lustrous, sparkling-metallic braunite crystals - about 4 nice large ones atop and many minute crystals elsewhere. The large crystals are to 9mm in size and are shockingly sharp and lustrous for the species. The complex form of these crystals is novel, and they had to be analyzed to ... |
