Your site looks nice. Here are some thoughts. There are a few items that need photos that are closer to the item or where the item is the focus (one belt has a default picture that is mostly the form it is on, and the belt is actually cut off on the bottom). Customers want to be able to see the item in detail. Many of your photos allow this, but there are some that need closer &/or more shots. Some items need specs added: measurements, materials, etc.
Think about how you shop for jewelry in person: you pick it up, turn it around, hold it where it would go on your body, consider the materials, measurements. The more you can provide that experience virtually, the better. Maybe check out other jewelry sites for ideas. If any of the items are handmade, hand-strung, etc. that should be noted, as that adds value (the time you put into it).
Finally, I think many of the items are priced too low. Consider the amount of time and energy you put into this, and take that into account. Value yourself more! Best wishes.
