As an 18-year-old, Ravikiran Bhat decided to cultivate pearls on an astrologer’s recommendation. But all the oysters he had implanted with nuclei (imported from Japan and made from oyster shells) died. That was 2005 and Bhat headed to China to study pearl farming at the Freshwater Fisheries Research Center in Jiangsu. “Pearl farming involves patience. How could I give up after one failure,” he says.
