The value of a piece of jewellery
The service of jewellery appraisals is often used by private persons for insurance purposes, by insurance companies or by notaries for inheritance cases. Gold jewellery is relatively easy to appraise: after determining the fine gold content (Karat), the weight in grams is measured with a gold scale, the value is calculated according to the daily fixed fine gold price, depending on the purpose it is needed (inheritance value, insurance value, replacement value).
For detailed appraisals of jewellery with gemstones, the precious stones have to be un-set, to obtain the exact weight and to be examined by the gemmologist. .
