Gemfields says unrest could disrupt Mozambique ruby mine
Gemfields said in a statement that "groups associated with the illegal mining and trading of rubies have taken advantage of the political unrest".
Anglo (AAL) American Plc’s Namdeb Diamond Corp., a producer of gems in Namibia, said it’s raising output at its Elizabeth Bay mine by 32 percent one year after resuming operations and plans to extend mining there beyond 2015.
