Calculate how much your gold jewelry would be worth if it were to be melted down. You will first need to find the current market price of gold, known as the spot price. You can get the spot price at Kitco.com, but it will be listed as the price per troy ounce (see Resources below). Divide this amount by 31.103 to get the spot price of gold per gram. Then use a digital scale to see how many grams your gold jewelry weighs. You now know what the wholesale melt value of your gold is. Never accept anything lower than this price when you are trying to sell gold jewelry. Sell your gold jewelry to a jewelry store in Boca Raton, Florida.
