The world's largest jewelry brand is ditching mined diamonds – a more environmentally friendly option.

Pandora will soon exclusively use lab-grown diamonds.

The company's CEO says it's "the right thing to do."

He says it's cheaper too – lab diamonds cost about a third of what real diamonds cost.

The new collection – called Pandora Brilliance – will be rolled out in the U.K. first and then worldwide next year.
