Gold is precious whether you find it refined or unrefined. In the event that you have been gifted or bought unrefined gold, you can find someone to do the refining for you. Be careful who you choose as your refiner because the product is too precious for you to lose. You might be having a lot of names when it comes to gold refiners but you have to look beyond the obvious in knowing the best person to work with. You need to ask the person the time it will take for the work to be done. It can take a few days to week. If the purity levels are high then the refining time should not be long. You do not expect high quality refining of a lot of product in a day which is why you should investigate the methods used a little further in such a case. If you are ignorant of what is going on around you then you might be overcharged. Ask about every charge that goes into the bill before you agree to the process. You need to get the charges in writing before you submit your gold for refining. Do not fall to the flat fee deals because most of the time they will not hold.
There is the question of whether you will be getting your original material back after refining. Rarely will you get back exactly what you took to the refinery. The refiners will do a sampling of what you have submitted to them, assay determination and then settlement after which the unrefined gold will be combined with others and processed. Nevertheless, do not confuse this to mean the product you submitted will be decreased or increased when you are getting the refined product. The truth is that at the end of the process you will be getting a pure metal but it might not be from the shipment you made.
Unrefined gold value varies from one batch to another. This is why you should insist on knowing about the analytical methods your refiner uses. For gold, the standard method for use in value determination is the cupellation also known as fire assay. Even though the refiner will do his or her best to give you the best assay results, you also need the valuation to be done by a third party so that you can compare the results. No one should make you feel bad about that. Make sure you know how disputed assay results are settled before hiring.
