I don't know about Ramona but if that is supposed to be a patent Riki I do not think it is authentic. I happen to have mine right now. I looked at your pics and compared them to my bag. Here are the two differences I noticed. In my blue patent Riki, the leather trim inside the bag where the name plate is in your first photo is NOT patent. Your picture looks like the trim inside that surrounds the plate is shiny/patent. The second thing I noticed is in the third photo. The "H" is off. If you notice in the first photo, the horizontal line in the "H" is placed not in the center but towards the top. That is how it should be. The "H" on the gold plate on the outside should be the exact same way. Instead, in your picture, the "H" is crossed dead center.
It is a really good fake but I think it is definitely a fake.
