Hi! I kind of feel showing too much jewelry might be like too much of a good thing. However you're promoting, web, print, you'll be able to support the logo with photographic images and headlines. I personally think the logo should be the cornerstone of this visual image, but not try to show everything at the same time.
It would be great to see some samples of your actual jewelry - do you have a link or anything that I might be able to view?
Thanks!
