Not to be outdone, Marc Anthony gifted the American Idol judge with a 14-carat blue diamond, worth over $4 million. “My favourite piece of jewellery that I own is a ring my husband gave me for our first anniversary," Jennifer told British OK! Magazine. "It’s a solitaire, a 14-carat blue diamond ring, a very rare diamond. It was a big deal, I’d been married a year.” Two multimillion dollar colored diamonds from two different men? If only I could be so lucky.
