Andradite : Ca3Fe3+2[SiO4]3, Hematite : Fe2O3 | |
|
N'Chwaning II Mine, N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa This specimen is just so beautiful and uncommon - sparkly maroon crystals of andradite on euhedral crystals of hematite. Even if you collect N''Chwaning stuff, I doubt you have one of these. 3.2 x 3 x 2.8 cm |
