The big way that your items get found in Etsy searches is by the tags you use with each item. One many items you aren't even using all 13, and many of them are one-word / not incredible helpful when you are using them. Work on your SEO. The jewelry market is HUGE on Etsy, so even with great tags/titles/SEO you're going to be competing with tons of people...with not-so-good, you'll rarely even get found.
