Winnie Wong / Peculiar Vintage

They may look like cotton candy but I wouldn't advise putting them in your mouth — these are "pollution" rings by Birmingham jewellery student Winnie Wong.

More from the cool series above (love those sliced, squared pipes).

Bonus link: play your own little part in reducing pollution by opting for recycled silver, which is what British designer Stef Warde of Peculiar Vintage uses in her modern, organic jewellery.

Even more jewellery:

• Plastic is Forever (Florida) - beach pollution
• Mareen Alburg Duncker (Germany) - contemporary metal
• Kali Jewellery (UK) - body pieces
