The brutal and high-stakes history of the global pearl hunt
In short: For millennia, pearl hunting has been a pursuit of extreme extremes. From the deep, shark-infested waters of the Caribbean to the hazardous depths of the Indian Ocean, divers have braved drowning, decompression sickness, and predatory attacks for a prize that is as unpredictable as it is rare.
Historically, pearl hunting was a grueling, manual process. Before the 20th century, divers had to gather massive quantities of molluscs to find even a few quality beads; it often took searching through more than a ton of oysters to find just three or four high-quality pearls. In Asia, while some oysters were found at shallow depths of 5 to 7 feet, divers frequently descended to 40 feet or even 125 feet on a single breath to find enough stock.
The industry has been defined by intense human cost and exploitation. During the Spanish colonial era in northern South America, indigenous populations were captured and forced into the dangerous work of diving. By 1558, a royal decree mandated that only African slaves be used for pearl diving in certain areas. These divers faced constant threats, including shark attacks, drowning, and physiological issues like hemorrhaging from rapid surfacing or intestinal problems from cold water exposure.
Economic and environmental pressures have shaped the trade's trajectory. In the 1930s, the Great Depression made pearl shell prices difficult to maintain, and over-harvesting had severely depleted oyster beds. This led to strict government regulations in the US and a total ban on pearl harvesting in Mexico from 1942 to 1963. Despite these shifts, pearling remains a significant part of history in regions like the Persian Gulf, where it served as a cornerstone of the Eastern Arabian economy.
