I see where the diamond is. The link to the video and some photos I pulled from it. What do you think?

I did not find the video helpful to seeing the level of detail, although it is possible that I did see a glint from metal a bit below the left collarbone at one point. I watched the video at full screen, and did not see it.
In the stills, even without zooming, I can detect it in your images 2,3 & 4, but not in 1.
The file I posted, I would agree, is not high quality. Some have posited that it is a compression artifact. I hope so, they are less expensive than diamonds, and I can afford to get a compression artifact for my wife! :great:
I played with the image a good deal with the tools I have available. I do clearly see something there, and I don't think it is only a JPG artifact. The color is a bluish hue as opposed to the rest of the area, and I can see a chain line going from it. If you change the image to grayscale or turn it into a negative image, it is a bit easier to see.
All that being said, to me the case does not hinge on stories from friends, ducks, necklaces or any of my gut feelings.
I think the computer evidence is the lynchpin. I know it has been called into question, but I am still of the opinion that it is valid.
There is other stuff too, like the harried cleaning spree and so forth. I am leaning BDI, but still open to hear valid evidence.
