MILPILLAS MINE, CUITACA, SANTA CRUZ MUNICIPALITY, SONORA, MEXICO
Dimensions: 5.5 X 4.1 X 3 cm.
In these azurite specimens, from this classic Mexican locality, several groups of crystals stand out, from tabular to prismatic. Well defined by the faces of the monoclinic prisms and truncated by pinacoidal forms. They have an exceptional brilliance and the intense color characteristic of this species. When the light “falls” on them, we can observe a marked color, thanks to a certain transparence. They are disposed forming rosettes, interpenetrating groups and also as isolated crystals. They contrast very aesthetically on a matrix covered with fibrous malachite crystals, with a delicate green color. Milpillas specimens can be considered among the best worldwide for the species, accompanied by the classics from Morocco or Namibia. The main crystal is: 1,3 x 1 x 0,4 cm. 0,51 x 0,39 x 0,16 Inc.
