I have compiled some details for informative reference in the pages here.
I have a selection of pictures from the biggest whole agate I have ever found at Binn hill, a variety of pictures of agate boxes I have been part of making, and also a reference to one of the most useful books in Agate collecting I have found.
If you have any questions on any of these things, please contact me here, or via my contact details at the top of this page.
