We picked these rough agate pieces in Ayrshire and brought them home to  polish. They have been through the tumbler with progressive grits to polish them up. 
There is a good listing for the Scottish carnelian lover. There are 8 self collected Ayrshire agates here, each about the size of a 5p or larger. 
These carnelian agates have a gorgeous orange glow to them. They have orange, red, pink, and yellow hues. 
There are a couple of banded pieces of agate here, but more eyes than we have ever seen in similar listings. They are a little small to sell individually but too pretty not to put out into the world 
A lapidary artist might be able to do something with these little agates and chalcedony pebbles.
