Group of very sharp fluorapatite crystals showing defined prism faces and hexagonal dipyramids. Good transparence, color between green to greyish, depending on light. Very aesthetically disposed on a matrix of muscovite hexagonal rosettes, with white dolomite. Also with some cyclic twinned marcasite crystals, very brilliant and defined. Take a look under magnication lens. An excellent specimen from this Portuguese classic mine.

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.

Mina de Miguel Vacas, Miguel Vacas Mine, Conceição, Vila Viçosa, Évora District, Portugal, Conceição, Vila Viçosa, Évora, Portugal

A good sized specimen partially covered by several libethenite crystals, very bright and accompanied by pseudomalachite. Under loupe we can observe pseudo-octahedral crystals, with transparency and intense green color. From a classic Portuguese mine exploted since Roman times.

RM1918   Libethenite and pseudomalachite

Mina de Miguel Vacas, Miguel Vacas Mine, Conceição, Vila Viçosa, Évora District, Portugal, Conceição, Vila Viçosa, Évora, Portugal

Specimens 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.
