RM2551 Panasqueiraite, triplite, isokite, quartz and pyrite
Minas da Panasqueira, Panasqueira, Covilhã, Castelo Branco, PortugalFrom specimens like these, this very rare species was identified: panasqueiraite. Identifying it in each sample is an almost impossible task. Panasqueiraite is a monoclinic calcium-magnesium phosphate, it would be an hydroxylated analog of isokite. In Panasqueira, its type locality, it is found as massive fine-grained aggregates together with other phosphates (fluorapatite, thadeuite, wolfeite, triplite, althausite and vivianite), with topaz, quartz and sulfides (arsenopyrite, pyrrhotite, chalcopyrite and sphalerite) in veins hydrothermal. The panasqueiraíta closely resembles the thadeuíta and the wolfeíta, but with the naked eye the three species can be distinguished by their slightly different colors: thadeuite: yellow-orange; wolfeite: pink salmon; panasqueiraite: pinkish orange.
Panasqueiraite crystals are not known, but there are always exfoliation planes {010}, also for thadeuite (Caries Curto, Jordi Fabre: The Panasqueira Mines. The Mineralogical Record, January-February 2014, volume 45, number 1).
Size: 5.2 x 4.6 x 2.7 cm.
Found in ±2005.

RM2166 Libethenite
Mostardeira mine, Glória, Estremoz, Évora, PortugalGroup of very good size libethenite crystals, with a deep green color, bright and well disposed on the quartz matrix. Samples of libethenite from the Estremoz area are not often seen. They could belong from Miguel Vacas, but the label of Manuel L. Adónis clearly indicates Estremoz, where similar specimens have been found.

RM1965 Arsenopyrite with fluorapatite
Minas da Panasqueira, Panasqueira, Covilhã, Castelo Branco, PortugalA first line arsenopyrite specimen from Panasqueira. It is a large group of prismatic lanceolate crystals of brilliant arsenopyrite, very defined, interpenetrated, with striated faces, ultimately: pure aesthetics. And to give it a touch of excellence we have a group of fluorapatite crystals, brilliant, transparent and with an uniform green tone. A more than worthy representative from this classic Portuguese mine.
Size: 9.4 x 7 x 5.5 cm.
Main crystal: 24 mm.
Found in ±2005.
Classic locality
RM1929 Actinolite and Fluorapatite
Montijos quarry, Monte Redondo, Leiria, PortugalFormer specimen of actinolite adquired in marzo de 1987 at the Sant Celoni mineral show by Sr. Manchion. It shows radial aggregates of green crystals of actinolite, with whitish fluorapatite prisms included in. It comes from a Portuguese quarries abandoned for decades.

RM1928 Arsenopyrite
Minas da Panasqueira, Panasqueira, Covilhã, Castelo Branco, PortugalThis floater specimen shows a curious and aesthetic skeletal growth of arsenopyrite crystals. Oquerous, extremely brilliant, with flattened and striated forms. An exceptional piece for this Portuguese mine that never ceases to amaze us for its top quality specimens. A very different specimen from Panasqueira.
Size: 8 x 4.6 x 3.6 cm.

RM1918 Libethenite and pseudomalachite
Mina de Miguel Vacas, Miguel Vacas Mine, Conceição, Vila Viçosa, Évora District, Portugal, Conceição, Vila Viçosa, Évora, PortugalSpecimens of libethenite from Miguel Vacas mine are seen in the market, but with this size of crystal, brilliance, sharpness and color not really many of them can be find, but rather few. You do not need a magnifying glass to enjoy the pseudo-octahedral crystals of this phosphate. It is accompanied by pseudomalachite, as is usual for the locality, and on a quartz matrix. A first quality one, yes!
