It's a simple and well-known pickpocket's trick. As he withdrew his hand after shaking Gabriel's hand, he slid the ring off of Gabriel's finger. As long as you keep the motion smooth enough, it's almost undetectable.

FWIW, I'm also wondering whether, if the ring has intrinsic magic of its own, it recognised one who has the right to it and aided him in the undetectable theft.
