Knowing Mutsu's personality and given the "cleft-lipped" smile she has on her face, she just picked up the ring after the admiral dropped it and put it on to tease her sister.

It looks like she picked it up to try it on and then hid it as Nagato walked back in the room. I don't think she was trying to tease Nagato.

Nah, there's not a hint of embarrassment on Mutsu's face which is why I think she's trolling. She has the same expression she had when teasing Nagato in episode 8 of the anime. If Mutsu were blushing after getting caught or had a more "typical" reaction, I'd agree with you.
I would also think the trolling route. I'm assuming that's supposed to be an engagement ring. Mutsu put it on her right hand (you're supposed to put it on your left).
