I'm not an expert but this is what I noticed:
You need to improve your photos. They are dark which makes it difficult to see the lovely details in your jewelry. Recently read that jewelry should be against a white background. I like the props, but don't think they should be the first photo.
If you want to sell in the US, suggest you also add metric measurements to your descriptions. Also, for me the description came up in French.
Relevancy is VERY IMPORTANT: Your item description should be at least 3 words and should be repeated in your tags. Use multiple words in your tags because people search using multiple tags.
Under your banner, in the info section, add more information about your shop and jewelry. Don't waste this space.
Check what other shops are doing. You don't have to copy but just get ideas of the kind of info they are giving.
Check out 'marketmyshop.com.' It's a good blog with lots of tips, as well as read other team and forum threads where people are asking questions.
When you list, check Etsy and google to see if your items are being found. If not, keep adjusting your titles and descriptions.
Know that it takes time to get your name out there in the internet galaxy. Just keep learning and working at it. Don't get discouraged.
Adding new items, renewing and expanding your section will improve your chances of getting found. Check your Etsy stats when you do this. Register with Google Analytics (stats are more accurate). You can do this through Etsy. Both will help you to track what people are look at, if you are being found, which countries, et.
Good luck and Happy Holiday Season.
