  • Pearls have been a source of fascination for centuries. They have been considered the most magical and feminine of all gems and are the only one created by a living organism. Pearls emanate a certain warmth and glow not found in other gems, due to their unique beginnings.
  • Pearls, one of the highly esteemed gems, are very valuable due to the high demand and prices for them. Several countries bordering the Indian and Pacific Oceans and some countries along the Eastern Atlantic Ocean have pearl oyster resources.
  • Many of the countries, particularly those in Asia, are very much interested in pearl oyster farming and pearl culture. Japan stands foremost in the two fields having developed technologies and innovations in the field.
  • India has one of the highest demand for pearls for setting in jewelry, and is particularly famous for its pearl oyster resources which yield superb pearls. The pearl oyster fisheries are located in two main areas: 1) in the Gulf of Mannar off Tuticorin coast and 2) in the Gulf of Kutch on the northwest coast of the country.
  • The principal causative factor in pearl formation in a pearl oyster is the presence of a nucleus. It can be of organic or inorganic origin, such as parasites adults or larvae, molluscan eggs, decaying parts of plants, sand grains, epithelium or blood cells of the same animal, etc. These tiny particles or organisms enter the oyster when the shell valves are open for feeding and respiration.
  • Cultured pearls are broadly classified into: nacreous layer pearls, prismatic layer pearls, and organic layer pearls. Different molluscs produce pearls of different colours. The colour of a pearl is usually similar to the colour of the shell nacre of the mollusc which produces it; this character is genetically controlled.
  • Pearl farming in general tends to be a long-term venture with large capital outlay before profits are realized. Spat collection is one facet of pearl farming that can provide fast profits to a farmer with limited capital outlay. In many parts of French Polynesia, people operate spat collection lines and sell the oysters directly to the pearl farmers who take care of the grafting and oyster husbandry.
  • The United States freshwater pearl industry is adding to the world’s natural pearl market. About 9 to 11 pounds of natural pearls are discovered for every 2,000 tons of freshwater mussel shells harvested to be used as nuclei in the cultured pearl market. The pearls are usually small, but a Tennessee fishery found a 16 mm white cultured pearl in recent years.
