RM3007   Malachite

Kakanda deposit, Lubudi, Lualaba, Congo, Democratic Republic of

These specimens of malachite present mamelonar, botryoidal to stalactic growths, with a very intense characteristic green color and silky luster. If they are observed under magnification, they show us that the sparkly green is produced by small malachite crystals that cover the surface. The photograph does not reflect all the splendor and brilliance of the piece. They are disposed on a fibrous malachite matrix. Very aesthetic.


Size: 11 x 8.5 x 4.2 cm.

RM2718   Kolwezite and cobaltoan calcite

Mupine Mine, Kamoto, Kolwezi mining district, Lualaba, Congo, Democratic Republic of

Exceptional 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. The average of various analyzes indicates a Co: Cu ratio of 1: 2.3-2.6, consistent with some results from other specimens with 1: 2 ratios. Various black aggregates appear in the sample, sometimes partially covering kolwezite, which corresponds to heterogenite. Also with small malachite crystals.
