A:

The Name is

 Katriel

Ever since my origin, I've been crowned by God

 Of Hebrew origin, the name means "crowned by God"

A male Israeli diplomat contradicts my feminine bond

 The name can be feminine, but also masculine, as evidenced by Israeli diplomat Katriel Katz

Spelled 3 different ways, my longest way is now bad
Because of a fraud to a profession that marvelous Marple had

 Variants include Katriela and Katrielle. I think this clue refers to Katrielle Layton from the Professor Layton games, since Katrielle is the daughter of a detective (The same profession as Agatha Christie's Miss Marple character)
