The two Sagenite agates are just beautiful specimens, the yellow sard is very compact and will make a beautiful piece of jewelry. The black one is rather coarse with the needles of sagenite right up at the surface (kinda looks like a face with the hair going straight up). It definitely has personality.
The enhydro agate is actually a cloud agate that also happens to have a water bubble trapped in it. The black cloud is a dark cloud like inclusion that just happens to look like a claw (no it is NOT a CLAW) just happens to be shaped like one.
