Most jewelry appraisers have some training in gemology and general jewelry making knowledge and techniques.
They focus in analyzing the quality of the gemstones according to color, clarity and quality of the cut.
They review the way the stones have been set and how the general piece was fabricated.
After carefully examining a piece of jewelry, an appraiser then determines its wholesale, retail and insurance values.
They determine the price based on the information they gather as to the making and provenance of the piece.
They also have ample knowledge of the current metals and gemstone market value.
