Emerald is a type of gemstone that belongs to the mineral variety known as beryl. It forms within metamorphic or igneous rocks under specific geological conditions. Emerald is technically classified as a mineral rather than a rock, but it is typically found embedded in host rocks like schist, granite, or pegmatite. Its vibrant green color comes from trace amounts of chromium or vanadium within its crystal structure. As one of the most valuable gemstones, emerald is highly prized for its rich hue and rarity. The most famous sources of emeralds include Colombia, Zambia, and Brazil, where geological processes favored its formation.
