Brazilian model Alessandra Ambrosio announced her engagement to jewelry designer Buck Palmer following a trip to Indonesia, where the proposal occurred by the seaside.

The couple has been in a relationship for approximately two years. While initial reports estimated the value of the cushion-cut diamond ring to be between US$ 200,000 and US$ 500,000, subsequent analysis by jewelry expert Roy Albers suggested the diamond may be between 5 and 7 carats with a retail value between $125,000 and $185,000, noting that Palmer’s profession likely influenced the final cost.
