6.8" Large Malachite with Azurite Specimen (6.7 Lbs) - Morocco

This large specimen displays small vibrant green, fibrous malachite crystal aggregations that are associated with breathtaking blue azurite crystals. There are azurite and malachite crystals on both the exterior, and lining small cavities throughout the specimen. The matrix is full of galena, some one which are visible on the exterior of the rock.

Azurite and Malachite are known to form in union with each other, for their chemical makeup is very similar. In fact, the presence of more or less water in the location of formation, is enough to determine whether an abundance of malachite over azurite, or vise-versa, will accumulate.

These minerals tend to be found near copper deposits, which accounts for the colors the minerals display. This association of azurite and malachite on copper rich, iron oxide matrix was found near M'Cissi, Alnif, Tinghir Province, Souss-Massa-Draâ Region, Morocco.

Galena is a lead based mineral that is in fact the primary ore of lead, and has been used for its lead content for thousands of years. Galena typically displays a gray metallic luster and forms cubes or octahedral crystals. The chemical composition of galena is PbS.
