I agree with Andrea. If you have priced according to the value of your materials, expenses and time it takes to make each item then don't undervalue yourself.
What are the stats for your views? Are people finding you through search or through external promoting? That will tell you where to focus more of your efforts.
That being said, since your views per day are decent, it is probably the descriptions, titles, pictures and maybe pricing that is throwing people off. For example; In the title you say the bracelet is "cultured pearl" which implies real pearls, and in the description you say "Swarovski pearl". Are they real or glass? Either way, truth in advertising is very important, especially when buying online. The description of your materials needs to be consistent all the way through your listing.
Some of your pictures are pretty good, but you need to make sure you have a consistent look and feel when displaying your items. That is what will attract people to want to buy your items. Minimal distractions in the background, fully displayed in the thumbnail, maximum saturation for color.
How do you come up with your pricing formula? If you think it might be pricing, experiment with a clearance section or reduction in prices and see if that entices people to want to buy.... that will tell you for sure one way or the other.
