Along with the Chalcopyrite there are also very sharp and lustrous Sphalerite crystals and the whole is bordered by lenticular crystals of Siderite. The upper levels of Panasqueira continue to provide surprising novelties, with specimens different from what was previously known.

ER49P6: Chalcopyrite with Tetrahedrite and Dolomite

Twinned very well defined and bright crystals of Chalcopyrite, with tetrahedral crystals of Tetrahedrite and small white crystals of Dolomite. We specially note the locality, a Chilean mine that isn't well known for such good collection pieces.

EBJ47CD2: Chalcopyrite with Tetrahedrite, Galena and Quartz

Chalcopyrite coatings on Tetrahedrite crystals with well-defined tetrahedral and tritetrahedral forms. They are on a matrix with aerial groups of Galena crystals and white Quartz crystals. From a mine famous worldwide for the quality of its specimens, this piece stands out for the good color of the Chalcopyrite despite the passage of years, and in general, for its harmony and beauty.

9EA70W2: Chalcopyrite, Quartz

A novelty at St. Marie 2012. Drusy growth, on matrix, of short disphenoidal crystals of Chalcopyrite, They have a second phase of crystallization, of granular aspect, that coats the faces of the first crystalline growth. They are with comb-shaped growths of Quartz crystals. A very representative piece of a mine that exploits polymetallic veins.

JFD68AO0: Malachite after Chalcopyrite with Dolomite

Eugui chalcopyrites in Dolomite, partially or totally pseudomorphed by Malachite, are classics. I kept this one because the Dolomite which hosts the Chalcopyrite is better crystallized than usual in these associations from Eugui.
