I try to stay away from fashion jewelry. Lesson learned from a pile collecting dust. Once in a while I come across some versatile ones, like this long and simple "floating circles" necklace from F21. It's lightweight, comparatively well made, and perfect for layering. Also bears a slight resemblance to the Lisa Taubes link chains. Dresses up the occasions without being too much. It's hard to be smart with buying "good" pieces, no?
