Our first and best recommendation is that you obtain an appraisal of your jewellery items. Many jewellers and retailers offer appraisal services for a moderate fee; in exchange, they will carefully examine your jewellery and provide you with a detailed report describing it, with magnified photographs, and an approximate “current replacement cost” estimate. This estimate, plus applicable sales taxes in your home region, tells you how much insurance you should purchase in order to ensure that you have enough coverage to replace the item in the event of a loss.
As global markets remain relatively volatile, the cost of precious metals and stones continues to fluctuate. To make sure that your coverage remains adequate, we recommend that you revisit your appraisals at least once every three years; in many cases, you can ask the original appraiser to provide you with an opinion as to whether or not your specific item will have changed substantially in value and if you should go to the trouble of a complete re-appraisal.
