JESSICA SIMPSON

According to jeweler Neil Lane, Eric Johnson wanted "the most romantic, beautiful, special ring" for his November 2010 proposal to Simpson. So he selected a three-stone sparkler with a 5-carat central ruby (the bride's birthstone) flanked by two pear-shaped diamonds that together total 5 carats.
