Carpe Minerals by Carles Manresa

MPB49CD1: Extremely unusual, especially for its orange-brown color. The analyses do not lie, so it is undoubtedly Anorthoroselite and it is also of good quality, with the crystal groupings in sheaves and with its slightly pink Calcite matrix. If you are looking for something different, this piece is it.
Agoudal Mines, Tansifite, Agdz, Bou Azzer mining district, Zagora Province, Drâa-Tafilalet Region  Morocco (2023)

Specimen size: 7.4 × 4.7 × 5.6 cm = 2.91” × 1.85” × 2.20”

Main crystal size: 0.9 × 0.6 cm = 0.35” × 0.24”

TPQ74CD3: Radiating groups of Erythrite crystals forming a very aesthetic complete rosette, with intense and deep color in clear contrast with the light-colored matrix partially covered by Quartz crystals.
A very unique specimen, difficult to achieve for its perfection, the quantity and quality of its crystals, which in this species are usually somewhat erratic.
Bou Azzer Mines, Bou Azzer mining district, Ouarzazate Province, Drâa-Tafilalet Region  Morocco

Specimen size: 4.9 × 2.9 × 3.2 cm = 1.93” × 1.14” × 1.26”

Main crystal size: 2.6 × 1.7 cm = 1.02” × 0.67”

CTX87CD5: Aggregate of cuboctahedral Skutterudite crystals with perfectly defined faces and edges, on matrix and extraordinarily lustrous, a property that has not been lost over the time since its collection.
This specimen comes from the collection of duplicates of Carles Curto (number 2011.18) whose digital catalogue file, handwritten label, and a previous label from Fabre Minerals, we will send to the buyer.
Bouismas Mine, Agdz, Bou Azzer mining district, Zagora Province, Drâa-Tafilalet Region  Morocco (04/2011)

Specimen size: 9 × 5.7 × 4.1 cm = 3.54” × 2.24” × 1.61”

Main crystal size: 1 × 1 cm = 0.39” × 0.39”

EBB47CD3: Aerial growths of Allargentum
that appear intergrown with Silver with a high mercury content, with some of the faces being well defined, and with small remnants of Calcite which has been acid-etched to reveal the sulfides and native elements.
These are important crystals for the species Allargentum, which is a much rarer species than Dyscrasite. In fact, until the appearance of these Bouismas allargentums, quality specimens were hardly known and, in general, had poorly defined crystals.
The piece has been analyzed and we will send a copy of the analysis to the buyer.
Bouismas Mine, Agdz, Bou Azzer mining district, Zagora Province, Drâa-Tafilalet Region  Morocco

Main crystal size: 2.7 × 1 cm = 1.06” × 0.39”

MBF37CD2: Profiled tabular crystals of Baryte, very intense in color and with inclusions of Realgar, showing geometric color zoning on the edges. They are on a matrix covered with rhombohedral flattened Calcite crystals. This piece, in a way, is the recovery of something that caught attention between 2013 and 2015 for its unexpectedness in that mine, and now with the addition of the Realgar inclusions.
This specimen has been photographed and published as a novelty at the 2023 Munich Show in the magazine ‘Lapis‘ number 12/2023, page 38
Bouismas Mine, Agdz, Bou Azzer mining district, Zagora Province, Drâa-Tafilalet Region  Morocco (02/2013)

The piece has a more intense reddish color on its upper half and more pink in the lower half, both with very bright luster and with concentric growths as can be seen on the back of the specimen that corresponds to the matrix.
The specimen comes from the collection of Paco Fernández and Carmen Valls whose handwritten label (number 5-020) we will send to the buyer.

Main crystal size: 2.3 × 1 cm = 0.91” × 0.39”

A beautiful association of this specimen of considerable size and very representative of what is found in the polymetallic Bou Nahas deposit.
Bou Nahas Mine, Oumjrane mining area, Alnif Commune, Tinghir Province, Drâa-Tafilalet Region  Morocco (2023)

Specimen size: 16.7 × 14.4 × 3.9 cm = 6.57” × 5.67” × 1.54”

This type of formation in the goethites of Sidi Rahal is rarely seen, and it has been seen in old or very old pieces like this one.
Sidi Rahal, El Kelaâ des Sraghna Province, Marrakech-Safi Region  Morocco

Specimen size: 7.7 × 6.2 × 5.8 cm = 3.03” × 2.44” × 2.28”

Main crystal size: 0.6 × 0.2 cm = 0.24” × 0.08”

HFB96CD2: Druse of Quartz crystals with acicular Goethite crystals, partially coated by a second generation of transparent Quartz, very shiny, and forming growths between stalagmitic and globular, completely hyaline.
This type of formation in the goethites of Sidi Rahal is rarely seen, and it has been seen in old or very old pieces like this one.
Sidi Rahal, El Kelaâ des Sraghna Province, Marrakech-Safi Region  Morocco

Specimen size: 7.4 × 4.9 × 4.6 cm = 2.91” × 1.93” × 1.81”

Main crystal size: 0.6 × 0.2 cm = 0.24” × 0.08”

MTX56CD1: In Sidi Rahal, these Quartz crystal growths (amethyst variety) that replace the walls of cubic Fluorite crystals, have slightly amethyst color tones, which is why this specimen is so unusual. Its intense color, equivalent to that of the amethysts from Brazil, gives this specimen a very high level of quality.
The Magazines ‘Lapis‘ and Le Règne Minéral‘ know this, and that is why they both reviewed it as a novelty for Munich 2023. Lapis on page 40 of their edition 12/ 2023 and Le Règne Minéral in its number 174/2023, page 25

Main crystal size: 13 × 11 cm = 5.12” × 4.33”

MRF28CD4: An interesting set of secondary lead minerals from the legendary Touissit. The matrix displays ancient molds of relict cubic Galena crystals and, thanks to an area of cementation, various secondary minerals derived from the initial lead sulfide, resulting in a partial coating of cream-colored Dolomite crystals on which whitish twinned crystals of Cerussite are intergrown with remnants of dark Galena and finally, a beautiful group of lustrous Wulfenite crystals with an intense yellowish color adorning the center of the piece, where they cover an elongated Cerussite crystal, larger and with a different habit and colour than the other crystals of Cerussite on the piece.
The specimen has been analyzed and we will send a copy of the analysis to the buyer.

Main crystal size: 5 × 3.7 cm = 1.97” × 1.46”

EAG96CD1: Unusual, both due to the fact that the crystal is isolated and well defined in its Feldspar matrix as well as for being so aerial, so free, so that its morphology is perfectly displayed.
Very few grandidierites have been found in matrix and even fewer so aerial.

Specimen size: 3.5 × 2 × 1.6 cm = 1.38” × 0.79” × 0.63”

MXF99CD1: Much deserves to be said about this piece, but the Mineralogical Record magazine's website has already done so, in its section "What’s New on the Internet Reports”, vol. 68, December 2023, page 9, and also, and very extensively, the magazines Lapis on page 37 of its 12/2023 edition, and Le Règne Minéral, no. 174/2023, page 26.
These dichroic fluorites from Nigeria have been seen at different shows throughout the year, but until now no specimens of significant quality had appeared. Are we going to see many more specimens of this quality? Is this piece, so perfect, going to be an exception? Impossible to know that now, but surely the year 2024 will show us whether this piece is a unique case or not. The only thing that is certain is that it is a very pretty Fluorite, whatever happens later with specimens from this locality.

In this case they exhibit good definition of the crystals, which is not very common in specimens from this find.
