Your shop is absolutely lovely, so don't get discouraged! The main problem is probably that jewelry is such a saturated category on Etsy that, unless you have something utterly unique, you may need a lot more items to get consistently high views.
Besides adding more items, my main suggestion would be to include a link to one of your other pages in EVERY listing. It could link to your shop's home, to a shop section, an in-shop search result, or to a listing for a coordinating item. I do it on all of mine, you you can take a peek at one of my listings if you're not sure what I mean.
This is ESSENTIAL. The vast majority of my views come from other pages in my shop... not from search. The longer you can keep a potential customer in your shop, the more likely they are to buy something.
Just copy the address of the page you want to link to and paste it into your description. Links within Etsy are automatically made active, so it's super easy!
Best of luck to you! And enjoy your vacation!
