- 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.
