I need advice, again!

As some of you may have seen, I have posted a Image of the Diamond Ring that I bought my Wife 20 yrs. ago.

However, I have found that photographing a Diamond Ring is not quite as easy as I thought it would be. I tried to capture the brilliance of the Diamond in the light box that I have. I used my Tamron 70-300mm Lens with Macro, which is the only Lens that I have with any Macro compatibility.

I set the AV to a higher number to get the whole ring in focus. The Image did come out better, thanks to some of the help you all gave me before. The problem is that I just can't seem to get the whole Diamond in a real, sharp focus. Some of it is a bit "blurry." I even wanted to try and capture the sharp cutting of the center Diamond. I did not use my Flash, as was explained earlier. The stand for the ring was about all that I could find, since I am by no means a Pro at this kind of stuff.

I know that I can do a better job, but just don't know all the "tricks of the Trade." If you, out there have any advice or better knowledge please do not hesitate to let me know what you think. You have done it before, so do it again. I do read what is explained to me.

I'm no expert either, but what about trying the photo against a dark background and have the diamond at some angle rather than straight on.

Try halogen light to bring out the sparkle, and maybe place the ring in it's box, if you still have it so you can photograph it from above.

A few things worth trying that may help. I personally would put the camera in manual mode and stick it on a tripod, if you have a shutter release use it, and use the Mirror lock up function

Try taking a three to four images and place your focus point (red dot) on different areas of the ring then focus stack them using photoshop. (don't move the camera)

Try taking a few images at f/8 f/9 f/11 to see which provides better focus. DOF gets shallow very quickly with macro work.

Try sandwich lighting the ring and use a softbox from above, i personally would pick a darker background. If you use a black background use -2 EV or -1.5.

If you are limited light wise use window light, or make some reflectors with tinfoil.

The key to getting this ring to shine is light, you just have to learn by trial and error and be creative.

Stephen interesting link thanks!
