Mineral specimens search results for [ Malachite (after Cuprite) ]

Aggregate of Malachite replacing dodecahedral Cuprite crystals. The former Cuprite crystals are very well defined, with smooth faces, a uniform green color and are on matrix.
A French classic that is with an old German label from an unknown collector that we’ll send to the buyer.

Specimen size: 2.2 × 1.7 × 2.2 cm = 0.87” × 0.67” × 0.87”

EM14AN2: Malachite after Cuprite

Malachite pseudomorphs after a complete floater group of dodecahedral Cuprite crystals, one of them clearly dominant.

Specimen size: 2 × 1.6 × 1.4 cm = 0.79” × 0.63” × 0.55”

Main crystal size: 1.2 × 1.2 cm = 0.47” × 0.47”

NT26AN2: Malachite after Cuprite

Malachite pseudomorph after a complete floater crystal of Cuprite, very sharp, octahedral, and beveled by dodecahedron forms. A quality French classic. This piece comes from the Ignacio Gaspar collection (number CUP-7), whose label we will send to the buyer.
Chessy-les-Mines, Les Bois d'Oingt, Villefranche-sur-Saône, Rhône, Auvergne-Rhône-Alpes France

EC14AD6: Malachite after Cuprite

Aggregate of Malachite pseudomorphous after dodecahedral Cuprite crystals, with smooth and very well defined faces, free of further alteration. A French classic and an excellent miniature.
Chessy-les-Mines, Les Bois d'Oingt, Villefranche-sur-Saône, Rhône, Auvergne-Rhône-Alpes France
Specimen size: 1.7 × 1.7 × 1.3 cm = 0.67” × 0.67” × 0.51”

Main crystal size: 0.9 × 0.9 cm = 0.35” × 0.35”

EA27AF6: Malachite after Cuprite

Complete floater group of very sharp pseudocrystals after cuprite, which are octahedrons beveled by the dodecahedron. The sample is from recent and surprising finds on the old dumps area at Chessy.

Specimen size: 1.8 × 1.5 × 1.4 cm = 0.71” × 0.59” × 0.55”

TP99AK7: Malachite after Cuprite

Floater intergrowth of octahedral crystals of Malachite pseudomorphic after Cuprite, very well shaped and larger than usual. A French classic of high quality.

EF66AN1: Malachite after Cuprite with Azurite

Floater group of Malachite pseudomorphs after Cuprite crystals with one of the crystals clearly dominant and with a sharp octahedral habit. Partially covered by groups of small Azurite crystals, an association that is not so frequent in Chessy, type locality for that species.
Chessy-les-Mines, Les Bois d'Oingt, Villefranche-sur-Saône, Rhône, Auvergne-Rhône-Alpes France

EJ47AE5: Malachite after Cuprite with Azurite

Classic aggregate of Malachite crystals pseudomorphous after Cuprite. They have an octahedral shape beveled by the dodecahedron and are on a matrix of tabular Azurite crystals.
Chessy-les-Mines, Les Bois d'Oingt, Villefranche-sur-Saône, Rhône, Auvergne-Rhône-Alpes France (2010)
Specimen size: 2.6 × 1.9 × 1.5 cm = 1.02” × 0.75” × 0.59”

TR73AJ3: Malachite after Cuprite with Calcite

Groups of Malachite crystals (after octahedral Cuprite), coated by a late phase of Malachite microcrystals. They are on a Calcite matrix. Pseudomorphs of Malachite after Cuprite are very uncommon at Tsumeb, and even more so with such large crystals.
Tsumeb Mine, Tsumeb, Otjikoto Region Namibia
Specimen size: 6.1 × 5.7 × 3.7 cm = 2.40” × 2.24” × 1.46”

The sample, very unusual, is from the Desmond Sacco collection whose label we will send to the buyer.
Tsumeb Mine, Tsumeb, Otjikoto Region Namibia (±1980)
