A diamond appraisal is a professional assessment of the quality and value of a diamond. There are several reasons why you may need a diamond appraisal, including: Insurance: If you plan to insure your diamond, your insurance company may require an appraisal to determine its value. An accurate appraisal can help ensure that you are adequately covered in case of loss, theft, or damage. Resale: If you plan to sell your diamond, having a professional appraisal can help you determine its fair market value and ensure that you receive a fair price. Estate Planning: If you plan to include your diamond in your estate planning, a professional appraisal can help you determine its value for tax and inheritance purposes. Curiosity: If you are simply curious about the quality and value of your diamond, an appraisal can provide you with valuable information about its characteristics, such as its carat weight, clarity, colour, and cut, as well as its estimated value.
