Call any and all reputable Jewelry Stores and Gold Buyers! There are plenty of the them around but you want the best prices, so ask what they are paying for scrap (i.e. for 10k, 14k, 18k) for the items you have to sell. Also, you might find someone on Craigslist paying a lot more but use due care. If you arrange a meet, weigh all of the items per their' purity ahead of time, agree on a public location where there will be a lot of people (inside a restaurant at a table is preferrable, as you have a good place to sit weighing scales and can take your time, as long as you purchase a drink or food or both) and always be careful when you leave with money in your' pocket. You can never be too safe, make your way to your vehicle and make sure that no one is following you. There are also companies like Kitco which pay pretty good prices but they buy below spot, you probably will have to establish an account and have a lot of scrap Gold as they don't deal in small amounts.
