The ring mystery

While proposing to Mrs Vigilant, Mr Brainy decided to play a trick on her.
He shows her two boxes A and B with a statement on the box:

Statement A: The statement on Box B is true and the diamond ring is in Box A

Statement B: The statement on Box A is false and the diamond ring is in Box A.

Without knowing if any of the statements on the boxes are true or false, Mrs Vigilant still managed to find the diamond ring.

So, where is the diamond ring, show me your whole proceedure of how you solve it. Pls reply and enjoy! :)

The diamond ring is in Box B.

Statement B says (Box A statement is false), so the diamond ring is not in Box A.

Only if both the condition in a statement is true, then it becomes true, which in this case:

Statement A: True, False = False
Statement B: True, True = True
