Avril Rocks 350,000

Avril Lavigne's engagement ring is worth a reported $350,000. The "Complicated" singer recently got engaged to Nickelback frontman Chad Kroeger and he has given her with a very expensive Rock. Jewelry expert Michael O'Connor added of the ring: 

"A pear shape diamond set in platinum is a nod to vintage glamour and individuality - perfect for a rocker like Avril. The half-moon diamonds are also rare since they would have to be specially cut to fit on either side of the center diamond. The center diamond is approximately 10 carats, with an additional four carats of total side diamonds."

Avril and Chad - who have been dating for around six months - celebrated their engagement by partying in Las Vegas on 8/21/12.
