Tom, it's close, but there is just a tiny bit of over exposure on the top of the clip, the detail is starting to wash out, Also I'm not seeing the contrast in the gold trim on the centerband. you might try stopping down a stop or stop and a half.
Or use a faster speed, I have no Idea of the parameters or you cameras capabilities, if you can, just bump the ISO up , any thing that will cut your total exposure, Nice lighting, hardly any shadow except just under the lower part of the finial ring, the tip looks perfect. Perhaps bouncing a light off the bottom of your setup, would accentuate the full round shape, and eliminate the tiny bit of shadow that's there.
This comes from a guy that spent a year and a half at New England School of Photography, but still haven't figured out my Nikon 8700 after having it for about 6 or 7 years. . I can do much better with my Nikon F-2 but film is a hard thing to come by these days.
I would settle for posting a picture like that any day.
