Cartier’s new LoveCharity bracelets cost about $500, but fashion editors and ad buyers got them for free at last night’s jewelry bash.

Held at the “Cartier Mansion” - a very fancy name for their store - the party boasted “celebrity designers” like Rihanna and Faith Hill wearing their expensive accessory, which is basically a colored silk cord bound by a gold rivet.

Regular customers buying the bracelets get to choose their charity - Julianne Moore’s goes to tuberculosis research, Djimon Hounsou’s aids children in poverty, etc. - and then $100 of their $500 buy goes to the designated foundation.

Last night was a little different - instead of credit cards, the fashion folk whipped out their IDs and were meticulously crossed and double crossed off a list before getting their hands on the tinkly bracelet.

Woe to the certain magazine cutie who asked if he could have an extra gift!
