Emerald is a precious gemstone known for its vivid green color. It is a variety of the mineral beryl and gets its green hue from trace amounts of chromium and sometimes vanadium. Emeralds can vary in color from light green to deep green and are often used in jewelry, especially in engagement rings. They are valued for their beauty, rarity, and symbolism, often associated with love and rebirth. Emeralds can have inclusions or imperfections, which are referred to as "jardin." They require careful handling and cleaning with mild soap and warm water. High-quality emeralds from sources like Colombia are particularly prized in the gemstone market.
