Would you wear a $450,000 engagement ring?

This week British actor Orlando Bloom and Australian Victoria's Secret model Miranda Kerr announced their engagement. (Um, if they have kids, they might be the most adorable babies ever.) Miranda looked adorable as she went to scout potential churches for the wedding ceremony with her mom and her Yorkie, Frankie, who never leaves her side. But we were so distracted by the giant rock on her finger that we turned into zombies.

Unfortunately we can't find a closer image of the ring, but it's a 5-carat diamond estimated to be worth around $450,000.

While we understand that these two lovely specimens can afford to spend nearly half a million dollars on a piece of jewelry, isn't it a bit dangerous to wear something that costs that much without, like, a bodyguard and homing device attached to it? Poor Megan Fox lost her new engagement ring on the beach in Hawaii as soon as she got it. Miranda, you better glue that thing to your finger!

Would you ever want a super-pricey engagement ring? And if you had one that expensive, would you actually wear it out? [Modelina]
