Pearl diving is the practice of searching for natural pearls in the ocean. Divers typically explore shallow waters, often using simple tools or free diving techniques to collect oysters, which may contain pearls. This activity has been a traditional livelihood in various cultures, especially in regions like the Persian Gulf and Japan. Historically, pearl diving was a dangerous occupation, requiring skill and bravery. Divers faced risks from underwater currents and marine life. Today, many pearls are cultivated through aquaculture, where oysters are farmed specifically for pearl production, reducing the need for wild diving.
