What is a good price range for jewelry on etsy?

I am thinking about starting an etsy account...I know it can be really tough to sell anythig on etsy, but am thinking about giving it a try. I make high quality sterling and semi-precious and precious gem stone jewelry. It is not the beaded crafty looking stuff that you see a lot of, but a lot nicer more similar to the silver items yuo see in a fine department store, like nordstroms. My question is, how much should the average price of things be for people to actually buy them? I think most peices will be priced around $80-$150...do you think people will buy at these prices? Any other tips on successfully selling on etsy?
