'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.
The couple were "super cuddly and affectionate"
as they drank Dom Perignon champagne and Grey Goose vodka in the gambling city on Tuesday (21.08.12) to celebrate their forthcoming marriage.
Meanwhile, a mashup of three of their hits Lavigne's "Complicated" and Nickelback's "How You Remind Me" and "Rockstar" has emerged online, and the results are hilarious.
