Many Brazilian agates have a dark rind of variable thickness and further in have a boring grey matrix. If you cut tangentially instead of just across the rind you can increase the amount of dark matrix relative to the interior grey and with imagination can produce scenes. Here are three examples. What looks like yellow scratches are color variations in the dark matrix. What is required is that you remove proportionally more of the interior grey thus accentuating the angle of exposure of the brown rind. Am I trying to hard?

Not trying too hard at all. Otherwise all you get is the same old fortification patterns.
Cutting rinds and heels is one of my favorite things to do, and you have illustrated why with your photos here.

Thanks for posting these Tom. I've encountered the same with Piranha Agates from Brazil. One in particular had "eyes" completely going around the perimeter - underneath the outer rind.
