How India is building a pearl farming industry
In 2016 Narendra Garwa was facing a desperate financial situation. His small book store in the village of Renwal, Rajasthan, was running at a loss.
With a family to support and little education, he searched the internet for other money-making ideas. He had some success growing vegetables in plastic bottles, but then came across a potentially more profitable crop - pearls.
"Rajasthan is a dry area with water issues. It was a challenge to think of growing pearls with limited water but I decided to try," he says.
Pearls are formed when a mollusc reacts to an irritant in its protective membrane. The mollusc deposits layers of aragonite and conchiolin, which together form nacre, also know as mother-of-pearl.
In the wild, pearl formation is rare so most pearls sold these days are from farmed molluscs, usually oysters or freshwater mussels.
