Might I use these earrings as an example -
http://www.etsy.com/listing/40378706/rose-quartz-pink-blush-dangly-earrings The first three words are the most important here on Etsy searches so those words should tell the customer what the product is. With these earrings the customer isn't told that until the 6th word. Using the color is a great word so I might retitle these earrings like this - Pink Quartz Earrings Dangly Antique Gold.
Restate your titles in the opening sentence of your listings and again three times throughout the descriptions if you can. I always list my tag words in the order of my title with multi word tags preferred. With these earrings I would use Pink Earrings, Pink Quartz, Quartz Earrings, Antique Gold Earrings...
I would also suggest getting the backgrounds of your photos all the same color - either the cream or the white - that will give your shop a more unified look.
I didn't look at your shop announcement, but that should state what your products are as your announcement is also part of searches.
Hope each piece of advice you are given is a help to you!
