Richard Burton used to splurge on jewelry for Elizabeth Taylor all the time, but they snagged headlines in '72 when he dropped over $1 million dollars on a 69.42-carat pear-shaped diamond (whoa, money was way cheaper back then). They even named it after themselves and had it on display. Of course they divorced and Liz auctioned it off for a $5 mil. You gotta hand it to Ms. Taylor, she had to be a freak in the bed to get a rock like that.
