Title: Pearl
Content:  Previously, natural pearls were found in many parts of the world. Present day natural pearling is confined mostly to seas off Bahrain. Australia also has one of the world's last remaining fleets of pearl diving ships. Australian pearl divers dive for south sea pearl oysters to be used in the cultured south sea pearl industry. The catch of pearl oysters is similar to the numbers of oysters taken during the natural pearl days. Hence significant numbers of natural pearls are still found in the Australian Indian Ocean waters from wild oysters. X-ray examination is required to positively verify natural pearls found today.
Title: Pearl
Content:   The ancient chronicle Mahavamsa mentions the thriving pearl industry in the port of Oruwella in the Gulf of Mannar in Sri Lanka. It also records that eight varieties of pearls accompanied Prince Vijaya's embassy to the Pandyan king as well as king Devanampiya Tissa's embassy to Emperor Ashoka. Pliny the Elder (23–79AD) praised the pearl fishery of the Gulf as most productive in the world. For thousands of years, seawater pearls were retrieved by divers in the Indian Ocean in areas such as the Persian Gulf, the Red Sea and the Gulf of Mannar. Evidence also suggest a prehistoric origin to pearl diving in these regions. Starting in the Han Dynasty (206 BC–220 AD), the Chinese hunted extensively for seawater pearls in the South

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 fragment of Isidore of Charax's Parthian itinerary was preserved in Athenaeus's 3rd-century Sophists at Dinner, recording freediving for pearls around an island in the Persian Gulf. Pearl divers near the Philippines were also successful at harvesting large pearls, especially in the Sulu Archipelago. 
Title: Hyderabadi pearls
Content:   Hyderabad is considered the main pearl trading centre in India, because of which the city is also known as the "City of Pearls". The most notable area devoted to the trade is the village called Chandanpet just outside Hyderabad, wherein almost the entire population is engaged in the delicate art of drilling pearls, a skill they have practiced for generations. This practice also makes the city one of the largest pearl drilling locations in India.
Title: Laccadive Sea
Content:  The Gulf of Mannar is known for its pearl banks of Pinctada radiata and Pinctada fucata for at least two thousand years. Pliny the Elder (23–79) praised the pearl fishery of the gulf as most productive in the world. Although extraction of natural pearls is considered too expensive in most parts of the world, it is still conducted in the gulf. Also collected in large numbers are Shankha mollusks (Xancus pyrum) whose shells are used as a ritual and religious object. Other mollusks of the sea are either too scarce or not popular in the Indian society and therefore have no commercial value. Another traditional occupation in the Laccadive Sea is fishing. The 
Title: Gold (color)
Content: South Sea Pearls, which have historically been cultured in the Indian and Pacific Oceans, in the countries of Myanmar, Indonesia, the Philippines, and Northern Australia but mostly attributed to the former thalassocratic Sultanate of Sulu have a gold colored variety from the Pinctada maxima Pearl oyster. This golden pearl is the national gemstone of the Philippines. This can now be manufactured in the laboratory at a much lower cost. 
Title: Gulf of Mannar
Content:  The Gulf of Mannar is known for its pearl banks of Pinctada radiata and Pinctada fucata for at least two thousand years. Pliny the Elder (23–79) praised the pearl fishery of the gulf as one of the most productive in the world. Although extraction of natural pearls is considered too expensive in most parts of the world, it is still carried out in the gulf. The chief seaports on the Gulf of Mannar are Colombo in Sri Lanka and Thoothukudi (Tuticorin) in Tamil Nadu. While these ports can accommodate deep-draft vessels, the shallow Palk Strait can only accommodate small shallow-draft vessels. In July 2005, the Indian Government took preliminary steps to go ahead with the Sethusamudram Shipping Canal Project, which would create a deep channel linking the Gulf of Mannar to the Bay of Bengal. Project boosters emphasize the benefits of a direct shipping route that connects India's east and west coasts without the long trip around Sri Lanka; environmentalists have warned against the grave damage such a project could cause to the sea life and fisheries of the Palk Strait and the Gulf.

Pearl divers near the Philippines were also successful at harvesting large pearls, especially in the Sulu Archipelago. 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

White and silver colored South Sea pearls tend to come from the Broome area of Australia, while golden colored ones are more prevalent in the Philippines and Indonesia. A farm in the Gulf of California, Mexico, is culturing pearls from the black lipped Pinctada mazatlanica oysters and the rainbow lipped Pteria sterna oysters. Also called Concha Nácar, the pearls from these rainbow lipped oysters fluoresce red under ultraviolet light.
Title: Industry in ancient Tamil country
Content:  expensive animal product that was imported from India by the Roman Empire was the pearl from the Gulf of Mannar. The pearls from the Pandyan kingdom were also in demand in the kingdoms of north India. Several Vedic mantras refer to the wide use of the pearls. The royal chariots were decked with pearls, as were the horses that dragged them. The use of pearls was so high that the supply of pearls from the Ganges could not meet the demand. Literary references of the pearl fishing mention how the fishermen, who dive into the sea, avoid attacks from sharks, bring up the right-whorled chank and blow on the sounding shell. Convicts were used as pearl divers in Korkai.
