2" Spectacular, Veszelyite Cluster on Hemimorphite - Congo

This is a 2" wide cluster of relatively large, vibrant blue-green veszelyite crystals that formed over hemimorphite. It was collected from the hemimorphite zone of the Palabanda Quarry in the Republic of the Congo (Brazzaville). It has been mounted to an acrylic display base.

Veszelyite is a rare secondary copper and zinc mineral that's found in the oxidation zones of base metal deposits. Crystals of veszelyite are typically emerald-green, blue or a mixture of the two. They can be found as small, lustrous clusters that are peppered across other minerals or as crusts, however in rare cases they can be found as dense crystal aggregations.

Veszelyite specimens from a recent (2019/2020) find in the Bouenza Department of the Republic of the Congo (Brazzaville) are a perfect example of this rare instance of dense aggregations of veszelyite. Within the hemimorphite zone of the Palabanda Quarry, irregularly dispersed formations of this rare mineral were unearthed. They occurred in small brecciated/weathered cavities where most of the veszelyite formed as crusts, while some spots revealed well formed crystals over hemimorphite. The area that contained these crystals was mined over five months, the final two of which appeared to indicate that the pocket was completely exhausted.
