In addition to the items you would like to have appraised, please bring your original receipt(s) of purchase and any and all certificates and previous appraisals that you have for the item(s). These documents can provide necessary details to ensure the accuracy of your appraisals, such as gemstone weights before setting. A small difference between actual weight and weight calculated by measurements can sometimes lead to a considerable difference in replacement costs, as can proof of purchase from different designers or companies.
