Pandora, the world's largest jewellery manufacturer, will cease using mined diamonds. In future the only diamonds it will use will be those manufactured in a laboratory. The reason for the move is concern for the working conditions of diamond miners, primarily in Africa. This is an extension of previous commitments made by the company to only use recycled gold and silver, and have all operations carbon neutral by 2025.

Their share price also rose 160% in the past year.

What's going on?
