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. You should not be letting someone you cannot trust handle the process. Even though you have the names of accredited gold refiners at hand, there are questions you have to ask yourself before deciding on who to settle for. 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. Also, be careful about people who promise to do the work in a day because there is a high possibility that they are taking shortcuts. 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. Do not take word-of-mouth when it comes to refining because if it is written, it can be used as evidence anywhere. Do not fall to the flat fee deals because most of the time they will not hold.
You should get an explanation on whether it is the material you take for refining that will be worked on and submitted back to you. You should not expect to get the gold you took there. It will not be economical to process your package only especially if it negligible but rather it is combined with others and processed. However, you will get a pure product that is equal to what you submitted. You will be receiving pure gold but not necessarily from the batch you delivered.
Not all gold that is mined in various places in the world will hold the same value. 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. 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 is your product and at the end of the day it is all business which is why you have a right to get a second and even third opinion.Make sure you know how disputed assay results are settled before hiring.
