Loupe Grading
Loupe grading is a fundamental skill in the jewelry industry where professionals examine and evaluate gemstones using a special magnifying tool called a loupe. This process involves carefully inspecting gems for their quality characteristics, including clarity, color, and identifying any internal or external features. It's similar to using a magnifying glass, but with much higher precision. This skill is essential for jewelers, gemologists, and quality control specialists in jewelry stores, auction houses, and gemstone laboratories.
