Jewelry appraisal is not always discussed at the time of purchase of fine jewelry. More often, the question becomes relevant later—particularly when an insurance company is reviewing a claim or when preparing for an international shipment. Imagine filing an insurance claim, only to have it denied because you submitted a gemstone certificate instead of an appraisal. That is when consumers discover that not all official-looking documents have the same legal standing. Insurance companies deny claims when a gemstone certificate is submitted rather than an appraisal, while international shipments may be delayed due to missing commercial invoices.
This article outlines what qualifies as an official jewelry appraisal in the U.S. and explains when it’s necessary for both insurance and customs purposes.
A jewelry appraisal is a written independent opinion of value that has been completed by a qualified third-party appraiser. An appraisal is typically requested for insurance coverage, estate planning, or international customs declarations.
An appraisal is not a sales receipt, proof of purchase, or a quality certificate.
There are three distinct types of documents:
In general, American consumers will seek an appraisal for situations related to insurance coverage, international shipping, or high-value custom jewelry. A common issue arises when there is confusion between different types of documents, which is often the reason insurance companies or customs brokers request additional paperwork or reject submissions.
Practically speaking, most insurers and customs authorities will request a copy of the appraisal along with supporting photos of the finished piece, and if the personalized jewelry contains gemstones, a laboratory certificate. As a rule of thumb, most insurance companies recommend that appraisals be updated every two to three years to account for changes in precious metals and gemstone market values.
According to professional ethics and industry standards, it is neither acceptable for a jewelry manufacturer or retailer to appraise its own merchandise. This creates a conflict of interest, since the seller would be valuing their own product.

Legitimate appraisals are conducted by:
This independence ensures that the valuation is unbiased and defensible, offering protection to the client.
A common misconception involves with laboratory reports. For instance, a GIA certification provides documentation of a gemstone’s characteristics; however, it does not assign a monetary value and should never be used as an appraisal.
With every custom or bespoke jewelry order, Olertis provides an invoice that includes the sale price, description of the piece detailing the metal type and purity, as well as gemstone specifications. Upon request, Olertis can also provide a more comprehensive set of documentation, including detailed information on materials and design parameters, if required for insurance or customs purposes.
If a jewelry piece contains gemstones that are supplied with original laboratory certifications, Olertis will provide these certificates to the customer. Laboratory certifications provide technical data that assists an independent appraiser in accurately identifying and analyzing the stones, but they do not establish monetary value and do not replace a formal appraisal. Most U.S. insurers typically require documentation to include photographs, weights and measurements of the gemstones, descriptions of the metal composition, and disclosure of whether the gems are natural origin or enhanced/treated. This documentation ensures that your independent appraiser has all the technical information needed to produce an accurate valuation.
At a customer’s request, Olertis will facilitate the gemstone grading process through a reputable laboratory such as GIA, IGI, AGS, or HRD, as a separate paid service. While infrequent, primarily for international shipments or custom jewelry valued over $15,000, Olertis may assist with arranging an independent appraisal as a courtesy.
Otherwise, customers select their own appraiser. Olertis does not influence the selection of the appraiser or their conclusions. When selecting an appraiser, U.S. customers are encouraged to choose appraisers who have well-recognized credentials, such as membership in the American Society of Appraisers (ASA) or the National Association of Jewelry Appraisers (NAJA).
Both ASA and NAJA require their members to meet rigorous education and training requirements, adhere to a unified code of ethics and methodology, and comply with court and insurer standards.
