A group of honey colored calcite crystals from the Berry Materials quarry. These are probably some of my favorite American calcites, both for their unusual, generally rounded form (vs. the rhombs and scalenohedrons that you find everywhere else) and their luster.
This one is included by numerous tiny ~ 1mm marcasite crystals.
A rhodizite-londonite specimen, with a yellow crystal on matrix.
A pseudomorph of goethite after magnetite, from a fumarole somewhere in Arequipa Department, in the southwestern corner of Peru.
These were found by a meteorite hunter who mistook the extinct fumarole for a metorite crater... (it's a long story... you never know who you'll meet when you leave your door open late at night in Tucson...)
It is structurally reminiscent of the Argentinian hematite ps. magnetite specimens from Puyun Volcano, though bears a textural resemblance to the goethite ps. marcasite pseudomorphs from Egypt.
Something new and interesting (though still rather ugly), for the collector of Peruvian material who already has it all.
