When it came time to choosing a ring for Ashlee Simpson, beau actor Evan Ross decided to keep it within the family, selecting jeweler-to-the-stars Neil Lane who also designed big sis Jessica Simpson's sparkler. "A Vintage inspiration with a Contemporary feel using calibrated cut rubies gave that vibrant Art Deco feel," Lane says of the 5-carat marquise-cut diamond accented with rubies and 140 small white diamonds. "The navette shape evoked the romance (of the) Edwardian Era."

Eric Johnson gave Jessica Simpson a 5-carat ruby ring in honor of her July birthday. "The ruby design for Jessica was perfection," says Neil Lane, the celebrity jeweler behind Simpson's engagement ring. "It's a classic design with a twist because the side stones are pear-shaped."

Angelina Jolie's 10-carat diamond is a one-of-a-kind cut thanks to Brad Pitt. "Brad had a specific vision for this ring," Beverly Hills jeweler Robert Procop said in a statement.
