Spike TV is to begin airing a reality series about divers that search for diamonds off the coast of South Africa.

Entitled Diamond Divers, the show debuts on the male-skewing U.S. cable network on June 20 at 10 p.m. EST. The 6 x 60-minutes series’ central star is Captain John, a “hardscrabble” type that leads a crew of six, including his hot-tempered son Jason, his ex-Marine father J.R., Mohawk-sporting diver Marty, his best friend Sam, and Doc, the ship’s medic.

The story arc follows the crew as they travel from Washington State to South Africa’s Skeleton Coast to mine for diamonds in the trenches of the ocean floor. Obstacles to overcome include sharks, 50-foot waves, harsh weather and poachers.

Diamond Divers was created and produced by Studio Lambert and American Chainsaws Entertainment. Executive producers for Studio Lambert are Eli Holzman and Stephen Lambert, while Duke Straub, Colt Straub and Royal Malloy are exec producers for American Chainsaws. Spike’s VP of original series Chris Rantamaki serves as the show’s executive in charge of production.
