That editorial does look great from what I can tell! I can't wait to see the HQ's. I love to see Kate in Vogue Paris, but then again I love Vogue Paris itself so I'd probably enjoy seeing just about anyone in it!
As for the ring. I have that book and while the pics are absolutely great, many of the IDs are incorrect and some are just out right fabrications and were completely made up by the author. Unfortunately you have to take alot of what is written in the book with a grain of salt because for the most part its just a great picture book. Most of what is written in it is just speculation and if the author was unable to ID a certain piece that was a fan favorite or its inspiration then she just made it up which I found really disappointing. I've never seen Kate wear a ring like the one described in the book and the one in the pic paper.flowers posted doesn't have onyx in it or tiger claws on it. It could still be true that she has a ring like that, but its just not the same one that she wears everyday. I'm absolutely positive that in the Grazia interview she said the one that inspired her new perfume bottle was Topaz which isn't always the brownish/grayish/tan color most people assume it is, but that also might not be the same ring that she wears everyday.
Honestly though WHO KNOWS! Other than Kate. We could all sit around forever piecing together quotes and stories about Kate's rings and trying to match them to ones that we've seen in pictures, but I doubt it would get us anywhere because there is really only one person who knows what rings she has and doesn't have, which she wears everyday, what inspired them, who designed them/where they came from, what stones they're made of, and things like that. That person is Kate. I doubt she is ever going to sit down and inventory all of her rings for us so we're probably all just wasting our time even trying to figure it out. Oh well...
