I want to sell my wedding dress & wedding ring set, how should i do it?

i have a nice wedding dresses embroidered with beads & pearls, very pretty, and also a set of rings (man's, petit engagement, and wedding band, all with small diamonds in the band) but the women's wedding band was cut off my finger by the paramedics. i want to sell them all, as i have been divorced, but not sure what the best course of action would be. i'm sure i should get the dress cleaned (but it's not stained or anything), but should i get the ring repaired or sell 'as is'? and where would be the best place to sell them each?
