You have a great shop! Lots of great items and they need to be known!! Like others have said, I would lighten photos a bit like in this one:
http://www.etsy.com/listing/84070809/cranberry-red-hoops-christmas-earrings?ref=pr_shopTry updating your tags and diversifying them a bit too. Like this one: Cranberry Red Hoops Christmas Earrings Sterling Silver
Try "Christmas Earrings, Cranberry red, hoop earrings, sterling silver earrings"
That way it is more relevant friendly.
Also in your description and tags (and I would even add it to my title), add tags like stocking stuffer, for her, for mom, for sister, bridesmaid gifts, bridesmaid jewelry, bridal jewelry
Adding these tags will broaden your customer base and be sure to tag some as "wedding" that way that large market will be able to find you.
Hope that helps! Good luck!
