Frederik Roijé / &design

Want to get married? Break things off! These porcelain pieces, when broken apart, become engagement rings. (As an added bonus, Kit Kat bars make delicious wedding favours.) Concept by Dutch product designer Frederik Roijé.

Bonus link: Tokyo's &design also makes break-apart jewellery. These sets, from their "Borders" series, are fashioned after plastic model kits.
