Chrysocolla on Malachite – Turquoise Domes above Finely Textured Green
Locality: L’Étoile du Congo Mine, Lubumbashi, Haut-Katanga, Democratic Republic of the Congo
Dimensions: 8 × 4.9 × 2.8 cm
A vivid turquoise landscape of flowing contours and prominent rounded domes, this chrysocolla-on-malachite specimen combines striking colour with a beautifully exposed mineral structure. Chrysocolla coats a thick, finely textured layer of malachite, whose dark green interior is revealed along several edges.
These side views are particularly engaging: the exposed malachite displays fine fibrous textures arranged in fans and radiating patterns. Above it, the blue chrysocolla follows the rounded contours of its substrate, creating a continuous, delicately textured surface. Several almost hemispherical domes rise above lower, gently merging areas, while numerous tiny dark specks add delicate contrasting detail.
The exposed green cross-sections and pale, locally brownish matrix frame the turquoise surface beautifully. Its predominantly matte finish gives the chrysocolla a velvety appearance, allowing the specimen to offer both an expressive display face and revealing views of its underlying structure.
Chrysocolla, a hydrous copper silicate, and malachite, a basic copper carbonate, form within the secondary mineralisation of weathered copper deposits. Their relative sequence is clearly visible here: chrysocolla coats previously formed malachite. The Roan-hosted copper-cobalt deposit of L’Étoile has a documented history of chrysocolla and malachite occurrences extending back to early mining records. The mine also holds particular mineralogical significance as the type locality of cornetite.
A distinctive collector’s specimen bringing together vivid colour, rounded growth forms and the intricate beauty of fibrous malachite.
In crystal healing traditions, chrysocolla is associated with inner peace, emotional balance and mindful communication. Malachite symbolises protection, transformation and emotional growth—together representing serenity and the strength to embrace renewal.
