Bound to be a winner! Looks like beautiful jewelry.
I am curious about several choices here.
Crop feels a bit long in the bottom. How did you decide on the crop/aspect ratio?
Sharpest focus in in the upper left third of the image and you have an interesting shift to OOF links and from silver to gold. My eye follows the loop down and then around, up the right side but it seems you want the main point to be the silver links on the left. Why this angle? Choice of DOF, Apart from eye movement around the necklace there is a bit of competition between the sharper sliver and the OOF gold.
