A nice cabinet sized sample of purple grape agate from Indonesia. I have seen some reports describing these as amethyst-- I am not sure if there is enough structure beyond the cryptocrystaline orbs to qualify these as "amethyst" and not chalcedony, but at the end of the day these are still pretty interesting specimens.
