Pearls are naturally formed an Oyster, a living creature - marine mollusks having a rough 
irregular shell; found on the sea bed mostly in coastal waters. There are natural pearls and cultured pearls. Cultured pearls are created by slight alteration in the natural pearl formation. Now an Indian scientist Ajai Kumar Sonkar has created cultured pearls in the form of Lord Ganesha.
The 42 mm Lord Ganesha-shaped pearl was created at Ajai Kumar Sonkar’s farm and research project in Andamans and
‘Earlier no free cultured pearl had been formed in the species, Pteria Penguin, because of its features. They are very sensitive to outside element and usually die when any foreign body is implanted,’ Ajai Kumar Sonkar said.
Sonkar, who in 2003 had developed the world's biggest black pearl in Andamans, said the usual 6 mm pearls takes about three years to grow in countries like Japan, but the Ganesha pearl was formed in just six months.
The scientist, who had carried out three surgical operations on the oyster to regulate chemical secretion which forms the pearl, said the entire process is based on 'mental activation process'.
Sonkar said crafts the nucleus, which is then implanted in the oyster. ‘Then the mental (part of the body that secretes pearly component) grows and envelops the nucleus. Six months later, a Ganesha shaped pearl is formed,’ he said.
