It take a while to make your first sale. Remember that etsy is a LARGE online market and the jewlery industry on etsy is full of great pieces so the competition is steep.
Just to give you an idea, if you search "jewelry" over 4 million items come up!
Try advertising your items and building a following through facebook, pinterest, twitter, wanlo (which ever you enjoy) post your things and other things you like.
Also, keep making and adding to your shop. My shop has 125 items and it is still hard to be found in such a vast market. So add to our shop so you will be found more frequently. And, finally check to make sure your tags are accurate. You can do this by searching the tags you used and seeing where your items show up. Then, reflecting if those are good tags, were the other items that showed up similar to yours.
