hi, Susan, I just joined this team and will try to give you my best advice. First, I think you have made a lot of lovely jewelry and your prices are just fine. The first thing that jumped out at me is that some of your photos are really dark! Is there some way you can make them brighter?
I have been reading the Etsy guidelines for titles and tags. They should match. When I make a title, I copy and paste it into the tag section and then add it. Your titles need to have commas between the phrases so that they will be found. I just looked at your (lovely) amber necklace for an example. Try amber necklace, amber beads, gift for teen, gift for women. 15" should go in your description because nobody will search for that, but they will want to know it when they are considering whether to buy it or not. Etsy says that phrases, rather than single words get more hits.
When I first looked at your shop, I saw so many different kinds of items that I doubted that you had made all of them. So I went to the place where you tell about yourself and found out that, yes! you did make all these things. Maybe you could put something like that in your shop announcement so people can see it right away.
Good luck! Hope this helps.
