What you are paying for.

Diamond prices are based upon their quality, which includes the criteria put forth in the 4C'S. One small change to any of the 4C parameters can result in a significant price difference. This isn't an issue if you have an accredited appraiser or gemologist making the purchase on your behalf, but for the ordinary customer it is "buyer Beware". Anyone in the trade will tell you that diamond grading is somewhat subjective, diamond appraisals from two independent evaluators can differ by one or as much as two grades due to each individuals vision, equipment, and general interpretation of what each grade criteria means. For a little more money you can purchase a diamond that has a GIA or AGSL report. This laboratory verification report guarantees the color, cut, clarity, and carat grade of any given diamond.The GIA or AGSL report is a world recognized document verifying your diamond's 4 C'S as being irrefutable. In some cases, the GIA or AGSL report registration number will be laser inscribed on the diamond girdle, an added method of identification that matches up with the GIA or AGSL report. The GIA or AGSL report will eliminate any subjectivity found in the appraisal issued by an appraiser or gemologist. However, you will still need the appraisal certificate from an accredited evaluator or gemologist to insure the ring against theft or loss.
