Azurite with Malachite

Description

Deep-blue Azurite druse covers a layered, open matrix, with green Malachite tracing the ridges and natural cavities.

From the Tongshan Copper-Iron Mine in Guichi, Anhui Province, this specimen presents patches of sparkling, deep-blue Azurite druse across a rugged, layered matrix. Green Malachite follows the edges and lines several natural cavities, providing contrast from the front and sides.

The reverse reveals the open structure and earthy matrix beneath the colourful display face. The specimen measures 55 × 50 × 30 mm and weighs 69 g.

The crossing arrangement described above is an important part of the specimen’s silhouette. It lets the direction of individual crystals be followed through the group, with open spaces making their outlines more apparent. Intersecting crystals alone do not establish a specific twin law; here the description concerns the visible arrangement rather than a laboratory-confirmed crystallographic relationship.

The recorded Malachite adds a second copper-mineral character to the specimen. Its green areas contrast with the other growth and help define boundaries, recesses and changes in texture. This relationship is an important part of the piece’s appeal: the minerals remain together on their natural setting, making it interesting for an association collection as well as for its principal mineral.

Azurite is a blue copper carbonate mineral that develops in the oxidised parts of copper deposits. It can occur as distinct crystals, closely packed sparkling growth, rounded aggregates and more massive material. These different habits give specimens very different textures even when the deep blue colour immediately identifies the main visual theme.

Collectors often compare Azurite by the relationship between its crystal surfaces and the underlying matrix. Larger faces give distinct reflections, while fine growth produces a more continuous sparkle. Blue tones can appear darker in thicker or shaded areas and brighter along exposed edges. Its natural shape and the distribution of growth across the piece are therefore as useful to study as the colour itself.

The recorded origin is Tongshan Copper-Iron Mine, Guichi, Anhui, China. Within a collection of Azurite specimens, this locality gives the piece a geographical identity alongside its particular crystal habit and natural setting.

The specimen measures 55 × 50 × 30 mm, with a recorded weight of 69 g. Its compact presentation makes it suitable for a boxed mineral collection, where the individual crystals and their association can be appreciated at close range.

Support the stable matrix or the supplied mount when moving the specimen, avoiding pressure on projecting growth. A secure indoor display allows its natural form and surface detail to be appreciated while protecting exposed crystal edges.
