Pearl Hunting - History

History

Before the beginning of the 20th century, the only means of obtaining pearls was by manually gathering very large numbers of pearl oysters (or pearl mussels) from the ocean floor (or lake, or river bottom). The bivalves were then brought to the surface, opened, and the tissues searched. More than a ton were searched in order to find at least 3-4 quality pearls.

In order to find enough pearl oysters, free-divers were often forced to descend to depths of over 100 feet on a single breath, exposing them to the dangers of hostile creatures, waves, and drowning, often as a result of shallow water blackout on resurfacing. Because of the difficulty of diving and the unpredictable nature of natural pearl growth in pearl oysters, pearls of the time were extremely rare and of varying quality.

In Asia some pearl oysters could be found on shoals at a depth of 5–7 feet (1.5–2 meters) from the surface, but more often divers had to go 40 feet (12 meters) or even up to 125 feet (40 meters) deep to find enough pearl oysters, and these deep dives were extremely hazardous to the divers. In the 19th century, divers in Asia had only very basic forms of technology to aid their survival at such depths. For example, in some areas, they greased their bodies to conserve heat, put greased cotton in their ears, wore a tortoise-shell clip to close their nostrils, gripped a large object like a rock to descend without the wasteful effort of swimming down and had a wide mouthed basket or net to hold the oysters.

For thousands of years, most seawater pearls were retrieved by divers working in the Indian Ocean, in areas such as the Persian Gulf, the Red Sea, and in the Gulf of Mannar (between Sri Lanka and India). A surviving fragment from the book Journey Around Parthia by Isidore of Charax, a 1st century geographer from the city of Charax on the northern end of the Persian Gulf, deals with the subject of pearl fishing.

Pearl divers near the Philippines were also successful at harvesting large pearls, especially in the Sulu Archipelago. In fact, pearls from the Sulu Archipelago were considered the "finest of the world" which were found in "high bred" shells in deep, clear, and rapid tidal waters. At times, the largest pearls belonged by law to the sultan, and selling them could result in the death penalty for the seller. Nonetheless many pearls made it out of the archipelago by stealth, ending up in the possession of the wealthiest families in Europe. Pearling was popular in Qatar, Bahrain, and some areas in Gulf countries.

In a similar manner as in Asia, Native Americans harvested freshwater pearls from lakes and rivers like the Ohio, Tennessee, and Mississippi, while others successfully retrieved marine pearls from the Caribbean and waters along the coasts of Central and South America.

In the time of colonial slavery in northern South America (off the northern coasts of modern Colombia and Venezuela), a unique occupation amongst slaves was that of a pearl diver. A diver's career was often short-lived because the waters being searched were known to be shark-infested, resulting in frequent attacks on divers. However, a slave who discovered an extra-large pearl could sometimes purchase his freedom.
