Photoshop ecommerce jewellery / jewelry

I have around 100 photos, they have been taken professionally and are quite good, but some of the rings are a little bit scratched and maybe it needs to visual editing to make it look shiner or brighten the picture but apart from that it should be quite simple.

If you have ever done product photography and photoshop please let me know. Maybe we can start off with 1 sample, and if I am happy, continue with the rest?
