Malachite on Dioptase on Matrix, Mindouli District, Brazzaville, Congo

From finds in 2018, this specimen is made up of a deposit of Malachite on a cluster of Dioptase which is on a host matrix with some small botryoids of Plancheite too. The Malachite under the microscope is made up of very nice gemmy green Malachite crystals in a bladed form. The Dioptase have good colour and lustre and although they are not all complete it is a nice specimen overall. The largest Dioptase crystal reaches 16mm and is not complete.

Size: 4.2 x 3.4 x 1.7cm

Locality: Mindouli District, Brazzaville, Congo.
