Cartier will replace the cord for you anytime, for free, and in any color you want. I don't have the Charity one that spells out L-O-V-E like in your picture. But I have the traditional Love one with screws all around it (about $600), and I have the Trinity one as well (about $400). I wear both of them together. I originally had black strings but got bored, so I recently switched to red strings. I just went into a Cartier store where I was vacationing (not the one where my bracelets were purchased), and they did it for me right away. The lady even told me to come back next week and she'll do a different color for me! I think black looks the best, but then red is also the traditional Cartier color.
