Black pearls are unique gemstones formed within oysters and mussels. Unlike traditional white pearls, they are known for their dark, rich colors, which can range from deep black to shades of green, blue, or purple. The most famous source of black pearls is the black-lipped oyster, primarily found in the waters of French Polynesia. These pearls are highly valued in the jewelry market due to their rarity and distinctive appearance. The process of cultivating black pearls involves careful farming techniques, where nucleated oysters are nurtured to produce these exquisite gems. Their beauty and uniqueness make them a popular choice for elegant accessories.
