appraiser
A person whose job is to judge how valuable something is.
An appraiser is a person whose job is to determine how much something is worth. When your family wants to sell a house, an appraiser inspects it carefully, noting its size, condition, and location, then estimates its fair market value. Insurance companies hire appraisers to evaluate damage after accidents or disasters. Art museums employ appraisers to authenticate paintings and determine their value before purchasing them.
Appraisers need specialized knowledge about whatever they're evaluating. A jewelry appraiser understands gemstones and precious metals. A real estate appraiser knows construction quality and neighborhood property values. An antique appraiser recognizes rare furniture styles and makers' marks.
Good appraisers stay objective and honest. They can't let personal feelings inflate or deflate their assessments. If you inherit your grandmother's old vase and wonder whether it's valuable, an appraiser examines it professionally, researches similar items, and gives you a realistic estimate, even if that means telling you it's worth less than you hoped. Banks, courts, and insurance companies rely on appraisers to provide fair, accurate valuations that help people make important financial decisions.
