Pictures of Jane's engagement ring?

I'm curious about the engagement ring Paul gave Jane in 1967. Does anyone have a picture to post of Jane wearing the ring? I have only seen pictures where one barely can see that she wearing a ring, but I haven't seen any pictures where the ring is clearly visible. I guess there should be pictures out there of Jane with the ring, the press must have caught her wearing it, probably at least in India and on other occations during 1968. Anyone?

I haven't seen any close ups of it - just those ones where you can see she is wearing a ring and that is about it!
