all corner either masons mitre or butt joints with 6mm half bull nose. honed and polished to same finish as face of tile.
for examples of 22.5° double mitre joints to form a 45° joint see my jotm entry for dec 2011
on the pewter trav job the edges on half tiled areas also half bull nosed.
I am not a fan of the eased 45° mitre joint on a external corner and would always use a masons mitre, also with a bull nosed butt joint the whole curved land is solid stone as opposed to the joint running through. the exception to this would be a 45° mitred joint filled with polyester filler tinted to match the stone and bull nosed to form a invisible join, I would still prefer a masons mitre finished the same way though.

understand Rob, you look top tiler, i am not talking only about natural stone only... (porcelain tiles also). agree easier with natural stone , you can do mitre , bull nose etc.
