If you’re an ageing billionaire bachelor planning to wed a supermodel half your age, you should consider looking into expensive engagement rings. Even if you aren’t, engagement rings are some of the most beautiful (and most expensive) pieces of jewelry you can buy. They’re certainly the most meaningful.

Diamonds have a long history of glamour and beauty. Worn by everyone from movie stars, to royalty to politicians, like Marilyn Monroe famously sang, “Diamonds are a girl’s best friend”. There are few things that elicit the same reaction from women as diamonds, especially when it’s an engagement ring.

Celebrity’s engagement rings are plastered all over magazines and the internet, showing the public some of the most extravagant engagement rings imaginable. Jennifer Lopez’s pink diamond engagement ring from Ben Affleck is probably one of the most famous in history. But is certainly wasn’t the most expensive.
