What is an appraisal?

A jewelry appraisal identifies and evaluates a piece of jewelry, including a monetary valuation. An appraisal should be updated about every three years to current market values. View sample appraisals by clicking on these links:

Why should I get an appraisal?

Every 90 seconds a burglary or robbery occurs somewhere in the United States. Many insurance companies will not insure your jewelry without current appraisals (generally less than six months old.) You are responsible for providing documentation of the value of your jewelry (appraisals) to your insurance company.

If you lose your jewelry today and file a claim tomorrow, can you tell the claims adjuster exactly what you had? Many people falsely rely on a sales receipt or simple three-line appraisals written by the salesperson, only to realize that the insurance company is going to replace the item not automatically write a check for a given dollar amount.

Proper appraisals display a magnified color photograph with a detailed legal description and proper identification of each of the gems with their color, clarity, shape, cut grade and measurements, as well as the gram weight and construction of the item, gold content, etc.
