In the 1960s, Japan had a global monopoly on freshwater pearl cultivation technology.
In 1972, A farmer in Zhuji experimented with seedless pearl cultivation, grinding clam shells into particles and implanting them into the clam bodies, successfully breeding low-cost pearls.
In 2005, Zhuji introduced Japan's "cell sheet transplantation technology", which increased the pearl diameter to 8-12mm and the perfect roundness rate from 15% to 40%. At the same time, the "ecological hanging culture" model was promoted to reduce water pollution, and the proportion of high-quality beads increased to 30%.
In 2023, Zhuji's annual freshwater pearl output was 1,500 tons (73% of the world's)
This is the story of the Zhuji Pearl City and it continues.
