He's right, I do like those. Great finds and the agate in matrix is one of the prettiest in-matrix examples I have seen. The other large one would likely polish up real nice. Even the smaller ones are really nice, especially the eye agate that looks naturally polished. Thanks for sharing.
I noticed some of your pics the rock is wet to show detail. Just a tip if you're interested, you might want to treat them with mineral oil to get a lasting similar effect. I soak my agates in mineral oil for about an hour, then I put them under a warm light while still wet for about an hour, then I dry them and put them under the light for another hour. You may want to test with one to make sure you like the effect (note, I find the agates look better the day after, initially they might be too shiny).
