Looks like a problem of a high kelvin lighting accentuating the color shift to me. First pictures are in different lighting and you can see some amethysts especially from the congo/rwanda area looking almost like tanzanite in certain lighting.
This is true. There are certain Amethysts from Africa, as mentioned the Congo, but also some Zambian and Rwanda, that act almost like tanzanite. They have a very bluish violet color shift.
