Brade Pitt codesigned this ring with Silvia Damiani. He wanted the ring to be tactile and the stones to be set on different levels. The overall shape is related to the concept of a heart and it is a symbol of eternity. This sparkler is estimated at around $500,000. They shared their engagement with the world during a Sting concert in New York City in 1999, and were married a year later in Malibu, CA.
