A professional jewelry appraisal is a detailed evaluation that establishes an item’s identity, quality, and market value by examining its materials, craftsmanship, gemstone characteristics, and condition; it typically includes clear descriptions, high-resolution photographs, measurements, weight, and the appraiser’s credentials. Appraisals serve multiple purposes—insurance replacement, estate settlement, resale, tax documentation, and lending collateral. Regular reappraisals are recommended because market values and replacement costs can change with shifts in precious metal and gemstone markets, while documented provenance or recent repairs also affect value. When commissioning an appraisal, request a written, itemized report and confirm the appraiser’s certifications, insurance, and conflict-of-interest policies to ensure an accurate, defensible valuation.
