What is a magnifying loop?

A magnifying loop, often referred to as a jeweler's loupe, is a small, handheld magnifying glass used to inspect fine details in objects such as jewelry, coins, or stamps. Typically featuring a convex lens, it allows users to view intricate features that are not visible to the naked eye. It is commonly used by jewelers, watchmakers, and collectors for quality assessment and examination. The magnifying loop is portable and simple to use, making it a valuable tool for detailed observation.
