I am not a pro at pics but I have purchased quite a bit of jewelry on etsy. As a buyer, my eye was drawn to the turquoise one you have featured mostly because the lighting on that one was the best. I also like to see items in gallery view and when I do that with your shop all I see are mugs, I would switch up your primary photos. The listings Sara provided are awesome examples of all that....white backgrounds, consistent lighting and variety in gallery view.
