This piece shows a botryoidal aggregate, of which we consider HCoO2 formula, according to the latest studies on the species. Intense black color, brilliance, waxy luster... A classic and very aesthetic definitive specimen. 4k20i

These specimens of brochantite from the mining area of Katanga are one of my weaknesses. The long needles of this mineral, filling cavities of the matrix, special green color, brilliance and silky luster... Pure aesthetic. I hope you enjoy it.
