A documentary/adventure film unlike any other. An exclusive, inside look into a closed fraternity of elite watermen. A breathtakingly honest, wild ride from start to finish. Black Coral tells the harrowing, amazing and occasionally amusing stories of the Black Coral divers of Maui. In their own words, the divers open up about friendships, rivalries, and the sobering realities of deep diving - the beauty, the addiction and the danger of harvesting the Hawaiian State gemstone.  Interviews include living and recently deceased dive legends Jack Ackerman, Ricky Grigg, Robin Lee, and more.
