What "NOVA" 10-th episode about

The pearl-the only gem produced by a living animal-has long carried a certain allure. Yet the best mollusk for making this gem-the pearl oyster-doesn't always produce a pearl, and even then, the pearls are rarely perfectly round. It wasn't until the late nineteenth century, when a Japanese scientist discovered a technique to incite oysters to produce these gems, that an industry was formed.
