A floater aggregate of lanceolated sharp azurite crystals with a more than excellent color and luster. From a mine not well represented in collections.

Size: 4.0 x 3.8 x 3.5 cm.
Found in 2007.

A very rich specimen formed by several azurite crystals that have been pseudomorphed by malachite showing original lanceolated forms, also tabular crystals with  velvety faces due to fibrous malachite. Azurite, with deep color, crystals also observed partially converted into malachite. The brilliance of both minerals is really good, with superb aesthetics. From a mine not well represented in collections and which nowadays is difficult to obtain fine mineral specimens.

A floater aggregate of lanceolated sharp azurite crystals with an excellent color and luster, with small malachite pseudomorph after azurite growths. From a mine not well represented in collections.

In this specimen we observe groups of brilliant galena crystals showing complex forms with parallel growths. Accompanied by some isolated groups of djurleite crystals, those are distinguished by having less brilliance, greyish tone and iridiscent reddish reflections. Prisms are presented as complex forms, rich in faces, with striations and twinned. Djurleite is an uncommon copper sulfide closely related to chalcocite. Published in LAPIS (2014).
