For insurance purposes you will want a full, complete, and highly detailed appraisal of each stone. An appraisal is a legal document you can present to insurance companies in case of damage or theft, for example, and it is also essential in the process of settling an estate. Insurance companies prefer that you keep your appraisals up to date, every three to five years
Appraisals for insurance/homeowners policies on higher valued items are listed/scheduled separately with underwriters. The best insurance appraisals describe gemstones and jewelry completely, clearly, and accurately, thus enabling the insurance adjustors to determine a proper replacement cost for a damaged or missing item. This report is an important document, similar to the legal documents that protect families and their assets.
