Although I've never really used magnetic therapy and can't make any scientific claims about them, Energetix still has tons of cute jewelry whether its for fashion, magnetic benefits or both. They even have products available for pets (that you can match with your own), charm bracelets and moveable bracelets (so you can customize a look). Energetix is also involved with charity organizations, particularly the Hugo Tempelman Foundation which helps prevent AIDS and improve living conditions in South Africa. Can't say no to that.

Here are some pieces I found on the site that I loved (all priced between £30-£65). You can find them all here (just toggle the language button to your own).
