Dwarves' Earth Treasures Museum: Thundereggs of Argentina
.
I first encountered encountered some Argentinan thundereggs
during the 2006 Tuscon shows so I don't really know that much about them.
The condor agates were so popular that some sellers would try to pass the
colored thundereggs from San Rafael as "Condor Agates" even they don't
share the same rock host. Those coming from Ayaleft contains blackish brown
to white agates often with "waterlines".

Those were passed as "Condor Agate",
but they are really thundereggs, not amygaloid nodules typical
of Condor Agates
