EJA97AQ0: New at Sainte-Marie 2023
A specimen that represents, apart from its evident aesthetics and its world novelty, a complete treatise on mineralogy, starting with a cobalt-bearing Dolomite (which has since disappeared during the process), followed by successive substitutions in which more copper was added, leaving as a final result Kolwezite-Malachite in pseudomorphic shapes after crystals of the initial cobalt-bearing Dolomite, and greenish blue Chrysocolla pseudomorphs after Baryte, with a stage of Malachite growth, also pseudomorphic after Baryte.
The discovery of this morphological and chemical complexity will soon be reported more extensively in an upcoming article in the French magazine Le Règne Minéral.
