Malagasy workers from an informal Sapphire mine seep soil through a strainer in the waters of a river looking for gems on December 2, 2016 on the outskirts of Sakaraha, Madagascar. Sapphires were first discovered in Madagascar in the late 1990s, and already the Indian Ocean island is one of the world's largest producers of the precious stones. / AFP / GIANLUIGI GUERCIA (Photo credit should read GIANLUIGI GUERCIA/AFP/Getty Images)
