Emerald is a precious gemstone known for its vibrant green color, which is caused by traces of chromium and vanadium. It is a variety of the mineral beryl, with its rich hue ranging from light to deep, vivid green. Emeralds are typically transparent, though they may contain natural inclusions, often referred to as "jardin" (French for "garden"), which are unique to each stone. These inclusions can sometimes affect the clarity, making them less than flawless but adding to their character.

Emeralds are highly valued for their beauty and rarity, especially those with a deep, even color and minimal inclusions. They are commonly used in fine jewelry, particularly in rings, necklaces, and earrings. Historically, emeralds have been associated with fertility, rebirth, and love, and they were highly prized by ancient civilizations like the Egyptians. Today, the most famous sources of emeralds include Colombia, Brazil, and Zambia.
