Is a diamond grading report the same as an appraisal?
No. A grading report describes the stone’s quality; an appraisal assigns a monetary value for a defined purpose such as insurance, estate, or resale. Owners who rely on a certificate alone can underinsure, overinsure, or misstate fair market value, because the certificate never specifies which market or value standard applies. Our appraisers examine grading documentation as part of the valuation, and specialized testing confirms whether a stone is natural, lab-grown, or an imitation.
What determines a diamond’s appraised value?
The 4Cs (cut, color, clarity, and carat weight) interpreted against actual market evidence. The inspection measures dimensions to confirm carat weight and assess proportions, then the appraiser researches recent comparable sales, especially auction and other recorded transactions, weighing how closely each comparable matches in quality, size, timing, and sale context.
Why does the purpose of a diamond appraisal change the value?
Because different assignments use different standards. Fair market value, the price between a willing buyer and willing seller, governs estate planning, tax filings, and probate, while retail replacement value, used for insurance, reflects current retail pricing and is typically higher. The same stone legitimately carries different numbers under each standard.
What makes a diamond appraisal defensible?
A transparent trail: the stone’s identity and grading basis, the stated purpose and value definition, and the comparable sales analyzed for quality, provenance, time period, and sale context. A report that gives a number without stating whether it is replacement or fair market value, or without citing market evidence, cannot be checked and is materially weaker in any dispute.
