I have seen a number of questions about selling gold jewelry, there was a great article in the Wall Street Journal about different options, I have posted the paragraph with the best option:
Overnighting Jewelry
Not good enough. I went back to the Internet and found a gold broker in the heart of Manhattan's diamond district, U.S. Gold Buyers, which buys and refines precious metals. A customer-service representative said the company pays 96% of the spot price for five ounces or more and on a sliding scale for lower weights. I could overnight my jewelry at the company's expense, and a representative would give me a quote the next day. If I declined the offer, the jewelry would be sent back at no charge to me. If I accepted, I could expect a payment to be processed within 24 hours. I could choose a wire transfer, or have the money sent via PayPal or by postal mail.
As reassurance that the company could be trusted, she gave me the company's license number with the Better Business Bureau and the New York City Department of Consumer Affairs.
Using the company's Federal Express account, I sent off the loot, and the next day a salesman called with a quote just as gold hit its new $949-an-ounce high. U.S. Gold Buyers' offer: $1,570.17.
Sold. My check arrived the following Tuesday.
