Thanks a lot for your kind comments , Thomas!!

These agates become from a new source in "Chubut" Province , Patagonia , Argentina. They were found during our last trip on March 2007 .Fortunately , they could be collected freely in an "Estancia" of a reletive to Claudia (my wife).
Land owners are now very "sensitive" on letting people enter their property.
If climate gets better , we will return there soon and stay for about one week

Can´t wait
