BANJARMASIN, Indonesia -- Cempaka Diamond Mine in southern Kalimantan, the Indonesian portion of the island of Borneo, is seen by some experts as one of the richest diamond fields in the world. A 166-carat stone and a rare blue diamond were discovered there in the past.
But with the halt of large-scale mining halted due to environmental and other problems, local people now engage in traditional methods of diamond hunting.
