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.

Big Agate!
