Are we sure it's a 31 crt ring?
Here's a transcript abut it:
Robin McGraw tells Rachael that her 31st wedding anniversary with Dr. Phil coincided with the first day of his show taping. "After the first show," she says, "we came back into the office and Phillip had rose petals all the way from the door up to my dressing room. And he had 31 long-stemmed red roses, 31 chocolate-covered strawberries, 31 chocolate kisses (which he said I could trade in for real ones) and 31 gift certificates to 31 Flavors ice cream. He had one last gift, and he said, 'OK, now this one you may think is too big but I hope you like it -- it's a 31-carat ring. I did think that was too big, but he actually had a dinner plate with 31 carrots and a ring!"
