The precious gem known as the "queen of gems" is the pearl. Pearls form within the soft tissue of a mollusk, typically oysters or mussels, as a response to irritants. They are unique among gemstones because they are organic rather than mineral-based. Pearls are often valued for their luster, smooth surface, and subtle hues, ranging from classic white to shades of pink, black, and gold. Due to their beauty and rarity, pearls have been used for centuries in jewelry and are symbols of elegance and sophistication. Unlike other gemstones, pearls require careful maintenance to preserve their luster.
