A diamond appraisal is the opinion of an individual appraiser as to the quality of a diamond and his/her opinion as to the monetary cost of replacing the stone. An appraisal is useful only as a tool for the insurance industry when a customer needs something replaced due to loss or theft. Appraisals are typically far above the actual retail cost of a diamond. A appraisal is issued by Jewelry King Inc.  that has had one or more staff members evaluate the the 4’c for its specific quality as well as the gold value. The appraisal certificate includes the listed retail value for authenticity and insurance purposes.
