APPRAISAL AND VALUATIONS
EXPERTISES
Appraising gemstones and jewelry determines their market value and requires in-depth expertise, gemological equipment, and extensive specific experience. In our analysis laboratory, we personally perform gemological analyses and all types of appraisals, from estate divisions to vault appraisals in Italy and abroad.
Each analysis or assessment is performed in front of the client and only after prior telephone appointment.
SAFETY BOX APPRAISAL
For over forty years, we have been appraising jewels and gems in our gemological laboratory, as well as in safe deposit boxes located in bank or private vaults.
Gemological analysis and subsequent appraisal are performed, where necessary, by two gemologists with all the necessary equipment; this shortens appraisal times, especially for large quantities of jewelry.
Our professional services can be performed in any vault in Italy and abroad, without geographical limits.
THE INSTRUMENTATION
Our goldsmithing skills and the equipment we have at our disposal allow us to dismantle and reassemble stones directly in the laboratory, on the same day.
Roberto Spagnolo and Fabio Spagnolo are the gemologists who analyze, appraise, and certify both in the laboratory and in national and international vaults.
