I would also recommend two other sites-
First and foremost would be Roger Pabian's agate page, which has
excellent photos of agates from around the world. I would also
recommend Pat McMahan's page,
particularly for plume agate and sagenite photos.
I also have started a (very) small collection of info specifically
on Arizona agate collecting sites at
And will gladly give any and all their propers if they wish to
contribute. I want to promote lesser known but none the less
beautiful agates obtainable in our state.
