By the end of our time in Yachats I had a pretty good handful of potential agates. Nick got me a rock tumbler for an early birthday present so I could polish them up. It seems that people generally polish rocks in four stages: gross shaping, minor shaping, pre-polish, and polish. I decided to skip the gross shaping step to keep my rocks in more irregular beachy shapes. The trade-off is that some of them would retain pits and depressions that won't polish up that well. I took photos before and after, because science. I think they came out pretty well. Each square in the pictures below is 1" x 1". Number 63 is my favorite.
