Blood, Sweat and Luxuries

Did anyone watch this last night, on BBC3.
I did (it is really relevant to my course) and it was really interesting. It's going to follow a group of 6 British consumers around the world investigating how their luxuries are made. Last night was the sapphire industry, and it was interesting to see how these are mined. The people mining are paid around £1 per day, If you can, catch it on iplayer. It was worth watching.
