Heidi Montag’s boyfriend Spencer Pratt of the MTV show “The Hills” has been telling people that the center stone is a pink diamond, The stone is in fact a lavender Amethyst. Spencer bought the ring from the Ice Accessory store at the Brentwood Mall where it retails for $2,890 . Still a decent price. Does anyone know if he has a job? On a personal note. cut the guy some slack, of all the guys on the show he seemed to turn out the best.
