A lot of people don't get sales in their first month, especially in major categories like jewelry. You need to create distinct branding and catchy pictures to stand out.
Here are a few tips though - your photos are on the darker side, and not very interesting. Great photos will really help you stand out in the jewelry section. Your titles are extremely important in getting found, the first three words are the way Etsy indexes you in search. Most of your items start with 'free shipping' but most people/no one searches 'free shipping' - you need to use relevant key phrases in your titles. Also slashes count as separate phrases, so make sure you write out 'blue green glass..." or "blue and green" rather than "blue/green".
For additional suggestions I recommend searching the teams for critiques, since anything else I could mention has already been talked about in other critiques and the selling handbook!
