Inca Agates
Foothills of Andes Mountains, Peru
    AAs of July 2013, the agates from Peru showed up and like the Condor Agates, they had to be dug out by hand and hauled down the foothills of the Andes Mountain. As typical of agates coming from the Andes, most agates are fractured from tectonic activities (and some mining efforts). The colors of the agates are generally watered down red, white and bluish-gray, but some had been found with brighter pink, yellow, red, orange and purple colors. Since many agates are fractured, they're usually best displayed by curvative polishing to preserve their exposed appearances and few minor fractures must be accepted. Some nodules are filled with llamellar psuedomoprhs (after calcite) and yellow to red plume inclusions.
    I noticed something interesting about the basalt/andesite host which the agates were extracted from is that they contain coarse feldspar crystals which I don't see in any agate bearing basalt rocks often and that will be their characteristic identity mark. That's a sign of the feldspar crystals forming in a magma before it spilled the lava out.
