The colors do look brighter but could be from the flash. My initial thought was newer - last pic of the "butterfly" almost looks like the looping you sometimes see on those contemporary "egg" type pieces of glass that sometimes end up with marble collections.
A Faceted pontil on the "butterfly" pattern is surprising, (most I've seen have rougher than normal pontils, and 1-1/4" would be the largest by far). I haven't seen them all, and of course now I'm really wanting to see other examples
