The Treasure Hunters - Season 1 (2014)

Ellie ventures down one of the deepest gold mines in the world in search of the gleaming metal that was once thought to be the skin of the gods and the sweat of the sun. Dallas free-dives for lustrous pearls in the waters around north west Australia and, using one of the largest treasure hunting machines, he seeks out diamonds from the bottom of the ocean.

Dallas braves vicious currents to dive on a shipwreck where gold, silver and 5,000 emeralds have been found. Ellie tells the tale of intrigue and obsession surrounding a jewelled room in Russia decorated with millions of pounds worth of amber; and she enters the secretive world of the diamond cutters - each lives with the knowledge that a slip of the hand could cost them millions of pounds.
