RM2718 Kolwezite and cobaltoan calcite
Mupine Mine, Kamoto, Kolwezi mining district, Lualaba, Congo, Democratic Republic ofExceptional specimen of kolwezite, which occurs as globular aggregates of olive-green crystals, partially covered by a yellowish earthy patina. They are disposed on a matrix of pink crystals of cobaltoan calcite. An exceptional sample for the species. We have analyzed it to check the content of Co.
