Just because the gold you have is not unrefined does not mean it is not valuable. There are times where you can find it unrefined and that means getting someone to refine it. You need to choose the refiner wisely though because you do not want to be putting such a valuable commodity in the hands of someone who is not trustworthy. There are some questions that can guide you in selecting the an accredited gold refiner. Prior to paying for the services or agreeing to work with a particular person, you ought to make sure you have talked about time it will take to get the finished product. You should expect anything from several days to weeks. If the unrefined gold you have has high purity levels then the work should be done faster. Anyone who promises to be done with processing of a lot of unrefined gold in a day should not be trusted easily because the work might be done halfway. You have to keep your eyes open and be more involved in every process so that you will not end up paying high for the services. Ask about every charge that goes into the bill before you agree to the process. Ensure you have a written price estimate before you bring your product to the professionals. Do not fall to the flat fee deals because most of the time they will not hold.
A lot of people will want to know whether it is the material they submit that will be submitted after refining. This is not usually the case in most situations. The professionals usually do sampling, settlement, and assay determination and then combine it with other materials for refining. Nevertheless, do not confuse this to mean the product you submitted will be decreased or increased when you are getting the refined product. There is no question of whether or not you will get a pure product but you should not expect it to be strictly from what you delivered.
Not all gold that is mined in various places in the world will hold the same value. This means you ought to inquire about the methods used in determining the value. Fire assay is the accepted method in determining the value of gold worldwide. Gold is highly valuable which is why you need the assay determination to be done by more than one person just to be sure. It does not mean you do not trust the refiner and if he or she is a good business person he should understand the reason for this. In case of assay results which do not match, you ought to know how such a conflict is resolved.
