I'm not planning on getting married anytime soon - have you seen the latest divorce figures? - but if I was I'd be looking at this 22 karat sapphire Quetico ring. It's made from recycled metal, produced to Fair Trade Federation standards and has a gem that was grown in a laboratory, so you can be smug in the knowledge that it didn't result in a minging quarry somewhere. It's also made entirely by hand and looks good. It's one of 28 pieces of jewellery from GreenKarat, which tries to use recycled materials and eco-minded refineries wherever possible. The company's US-based, but ships regularly to the UK, Australia, Canada and the Netherlands. Thanks to the weak dollar, this ring would cost about £650 if you live in the UK.

Isn't that what pawn shops and yard sales are for...recycling jewelry?
