Appraisal FAQs

A professionally qualified appraiser will deliver a detailed, written appraisal report that is independently and impartially prepared, offering an expert opinion on the quality, characteristics, and value of each jewelry item. This comprehensive report includes thorough documentation such as gemstone identification, metal type, craftsmanship, condition, and relevant market data supporting the valuation. To enhance clarity and record-keeping, each appraisal also features high-resolution color photographs of the items from multiple angles. Our reports are designed to meet industry standards and are suitable for insurance, estate, legal, or resale purposes.
At Lauren O. Inc., each jewelry item is professionally cleaned prior to examination to ensure the most accurate grading and valuation. To the best of our ability, all stones are checked for security in their settings, and any visible repair needs or structural concerns are carefully noted in the appraisal report.
To insure an accurate assessment of your jewelry, bring any documentation you have on your jewelry items to the appraisal appointment. Be sure to include sales receipts, diamond or gemstone lab certificates, warranties, old appraisals or insurance summaries, and any documentation that details factual information regarding the history or provenance of your jewelry item.
Appraising your jewelry will safeguard your investment if it ever becomes lost or stolen. If replacement or settlement becomes necessary, the accuracy and detail included in a Lauren O. Inc. appraisal makes it possible to identify your jewelry items or to have exact duplicates recreated.
A comprehensive written appraisal is accepted as proper identification by most authorities. A valid appraisal is particularly important in proving your claim on lost or stolen jewelry, or proving ownership if traveling to a foreign country.
A current and objective appraisal will indicate the appropriate market value of your jewelry item. This valuable information can be used to determine if your jewelry is adequately insured and will take the guess work out of calculating insurance coverage and premiums.
