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”
.
MT93AI8: Malachite after Cuprite with Mimetite
Small groups of Malachite crystals after dodecahedral Cuprite. They have very well defined faces and edges and are on matrix with a divergent spray of acicular Mimetite crystals.
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)
Specimen size: 7.6 × 4 × 2.9 cm = 2.99” × 1.57” × 1.14”

EM47Q8: Malachite and Azurite with Quartz
A novelty at Ste. Marie 2010. A group of Quartz crystals, totally or partially coated by limonite and botryoidal growths of small crystals of Malachite, plus groups of small but very well-defined Azurite crystals with a deep blue color and excellent luster. The M'Cissi area lies within Alnif Commune, Tinghir Province, Drâa-Tafilalet Region, along the northern margin of the eastern Anti-Atlas. It is a region rich in Paleozoic outcrops where Ordovician and Devonian sedimentary sequences were affected by Hercynian tectonics and later hydrothermal events. Around M'Cissi, sulfide and iron oxide mineralizations are common, as well as quartz–carbonate veins that occasionally host accessory species like Azurite and Malachite, formed under low-temperature hydrothermal conditions.

TMT66CD6: Malachite on limonite
Group of coralloidal aggregates formed by Malachite crystals of uniform grass-green color on limonitic rock matrix from the Tazalarht mining district in Morocco.
Tazalarht mining area, Taroudant Province, Souss-Massa Region  Morocco (2023)

MEB87ASN5: Malachite on Quartz
New find in Munich 2024, featured in edition 56, number 1, of the Mineralogical Record magazine. Group of Malachite crystals, of considerable size for the locality, with well-defined faces and edges, and a very uniform deep green color, which have grown on a hyaline and well-defined Quartz crystal. The specimen has been analyzed and identified as Malachite, and although a pseudomorph cannot be ruled out, this possibility seems unlikely to us, given the appearance, shape, and great luster of the crystals. The Tazalarht mining area continues to offer pleasant mineral surprises.

TV48N0: Malachite pseudo Azurite with Quartz and Chrysocolla
A novelty for Tucson 2009. The Malachite has replaced very well defined crystals of Azurite, some of them doubly terminated. The matrix is a thin layer of very bright crystals of Chrysocolla. This association is very rare at Milpillas and only a very few specimens arrived to the market.
The specimen has been published in the magazine ‘extraLAPIS’ on page 83, number 45, "Kupfer Mineralien" and in the monograph 'The Milpillas Mine' of the ‘Mineralogical Record‘ magazine on page 596 in the volume 52, number 5, September-October 2021
