If the jewelry is gold, you can try to the "cash for gold" thing..
Also you can go to most jewelry stores now and they will buy gold, precious stones and the like.
You can go to a pawn shop and sell the stuff as well.
I took the laptop I am writing on now there about 2.5 months ago.
I took this in trade for an old car I had.
the value is about 600 dollars.
At the pawn shop, I pawned it, for 200 dollars. I asked that if I wanted to sell it, what would the price be?
They said 200... they would probably mark it up 150 or so, but they had better laptops for about 350 on DOWN....
They will send you a letter to let you know that you have a certain amount of time to reclaim your property, they usually charge 20 dollars per 100, so if you pawned it for 200, you would have to pay 240 to get the jewelry back.. If you pay the 40 by the first 30 days.. you can then reclaim it for a bit over 200.. OR if you wait another 30 days...
it would be 240 again.
This is just an example but I hope it helps.
