Think like a customer-
example
http://www.etsy.com/listing/103161052/free-shippingbubblebubbleuv-blacklightIf you were looking for something like this necklace, what words would you use to search for it? Free shipping? No, but those are the first words you use in the most important part of your listing. Use words that a buyer would use to find a necklace. That is SEO, search engine optimization. Listing your items with the keywords that will get customers to your listing.
I'd give you some suggestions but you haven't given me any information about your item in the description, how long is it, what is it made of, how is it made, is it adjustable, what it the stone? When will I receive it, how is it shipped?
This is your only chance to explain to your customer all the things they want to know. If they don't find it they'll just go to another shop that has more information.
You can get a lot of information here in the Seller Handbook on the ETSY blog. It helps to read up and learn from others.
