I like your pictures - you don't need to click through to see what they are, that's nice. A lot of people take them from so far (or don't crop them) that you're not even sure what you're looking at.
I like the shop selections by type, but I'd go for standard text, not all caps as it seems like shouting. Maybe NEW should be all caps, for attention?
I don't do a lot of jewelry making to know pricing, I'm just looking at appearance.
