I love love love
Violet. It's unassuming and gorgeous and way underused (which is a good thing because I want to use it).
Violette is too frilly. It goes well with
Jewel, although I'd use something a bit less ostentatious to go with
Violet.
Jewel's a bit glitzy. Even
Jade and
Violet would be good, or
Ruby and
Violet.
