Having a diamond ring on your finger is always a little scary - what if it falls down the loo or gets stuck in a grate? But in celebville stars don't just wear a classic gold band with a single diamond. Nope they wear their very own Hope diamond on their wedding finger.
So who wins the award for the most blinding, ostentatious ring ever? Well Jennifer Aniston's diamond is anything but discrete and who could forget JLo's pink dazzler she was given Ben Affleck back in 2002. Beyonce must have a mighty strong index finger to carry the weight of her 18 carat blinder.
The most ridiculous ring in terms of cost per wear goes (of course) to Kim Kardashian. Kris Humphries proposed to her with a Lorraine Schwartz diamond ring which was 20.5 carats in total. It was estimated at two million dollars - which is nearly $30,000 for each day of their 72 day marriage.
Can you guess which rock belongs to who?
But it's not all about the price tag as some celeb engagement rings are sentimental as well as large enough to require their own personal security guard. Katherine Heigl's band used half of her mother's engagement ring and of course Prince Wills proposed to Kate with his mother's saphire.
Kate Moss has one of the best stories behind her ring bling, as apparently Jamie Hince tried to track down Zelda Fitzgerald's original 1920s engagement ring. He didn't track down the diamond, but he found original sketches of the ring and made Mossy her own version. How romantic is that?
