I was digging around in a drawer not looked in for ten years and found a pair and a half plain gold earings, five or 6 odd silver earings, 1 chunky silver necklace and 3 old silver rings. 2 of the rings are broken zirconia and sapphire i think and 1 is opals and silver half eternity but one of the opals is missing. Is it worth selling any of it or shall i just chuck back in the drawers?
