The diversity of items will depend on your employer, ranging from contemporary, mass-produced items to unique antique or custom-made pieces. You'll routinely assess both precious metals and gemstones for authenticity, quality, and sometimes value, using specialized tools and testing methods. This varied workload keeps the job interesting and helps develop a well-rounded expertise in different types of jewelry.
