10K gold necklaces, all from Riddles Jewelry - $100-$200 each, depending on the necklace (see sets of pictures). Some are adjustable and some are not. (Picture of three are the $200 each--they were $500+ each brand new. Picture of four are $100 each, including Black Hills gold necklace with 2-leaf pendant--they were each $200-$300 new.) Gold chains vary in length, up to the longest being 22 inches.
Also, one gold and diamond (real diamonds) pendant - $50 (I'm not sure how much the pendant is worth out of the total, but I use the chain it came with for a different pendant.)
Sterling silver necklaces (most from Riddles) - $10 each
I no longer wear these, and all are in excellent condition.
