Emeralds are among the most prized and valuable gemstones, known for their vibrant green color and association with luxury and royalty. They belong to the beryl family, which also includes aquamarine and Morganite. Colombian stones often have a premium price tag. Almost all emeralds contain inclusions, earning the term "jardin" (French for "garden"). Oiling is generally accepted, but stones with synthetic fillers rather than natural cederwood oil or resins, are less valuable.
