The world's biggest jeweller, Pandora, says it will no longer sell mined diamonds and will switch to exclusively laboratory-made diamonds.

Concerns about the environment and working practices in the mining industry have led to growing demand for alternatives to mined diamonds.

Pandora's chief executive, Alexander Lacik, told the BBC the change was part of a broader sustainability drive.

He said the firm was pursuing it because "it's the right thing to do".

They are also cheaper: "We can essentially create the same outcome as nature has created, but at a very, very different price."

Mr Lacik explains they can be made for as little as "a third of what it is for something that we've dug up from the ground."
