The Ring

Ok I can’t tell at the end if Jane puts the ring on. Around 9:08 the camera does the glitchy thing but she makes a quick movement and the it cuts and you can just see her right hand and it looks like ring is on her ring finger. Is she accepting the ring as commitment (I would say a promise ring but it doesn’t seem like the right word because of the way Rochester joked about the promise and inviting friends) or is she saying yes to the wedding?? But then why the right hand??
