Both mounted and unmounted, the stones look stunning! However, I agree, the ring thingy is bothersome to me. And, I know I'm a pain, but watching the ring videos, I want the circling to stop so I can take it all in. Reminds me of this:
Also, as others said, i can't help but wait for the camera to pan down to view the piece from other angles, especially the sides.
In a nutshell, it's all about envisioning the piece on my hand, and I want to see the piece in the same way I'd see it on my hand ... same distance from my eyes, same slow movements to watch the scintillation, same view from above and from the side. If this is one part of the presentation puzzle, that's fine. However, it requires a LOT of painstaking work from you not to be the entire presentation! FWIW, D, I love your "signature" look photos and I'm ALWAYS in for a great hand shot.
