Madonna has turned to Chopard to create the custom diamond knuckle ring that reads “M-dolla” and the Happy Diamonds cross she wears on the cover of her new and much anticipated album “Hardy Candy.”

Designed by Chopard co-president Caroline Gruosi-Scheufele herself, the ring features 258 brilliant cut white diamonds with the signature Chopard floating diamonds in the flourish of the letter M. This is the second partnership between Chopard and Madonna; their first was the pave diamond “Hung Up” necklace the Pop Queen wore onstage from her “Confessions on a Dance Floor” album.

The “Hard Candy” album cover has a WWE-like wrestling theme with Madonna wearing a black leotard, thigh-high black boots, a WWE-like wrestling title belt, black gloves and, of course, the Chopard M-dolla ring and the diamond Chopard cross with 3 diamonds.
