An antique charm bracelet I've been putting together for several years, with over 100 sterling charms ranging from Victorian to 1960s. I really love the mechanical ones.
And an antique Edwardian diamond ring from my failed engagement...I really do need to bite the bullet and sell it, but it's still very fresh, so I've hidden it away in a box and tried to pretend it doesn't exist, instead.
Other than that, I don't really wear jewelry, ever.
