Very aesthetic specimen composed of numerous botryoidal aggregates of blue chrysocolla, scattered across a rocky matrix. Featuring green radial aggregates corresponding to malachite, along with black globules of tenorite coated by chrysocolla. The contrast on the matrix is highly striking.
Although similar pieces initially circulated with erroneous labels attributing them to the Tentadora Mine (Pisco, Ica), the locality was subsequently corrected and confirmed by R. Lavinstky and U. Kolitsch as originating from the Julcani mining district (Huancavelica).
