It's Oscar season, which means only one thing: more diamonds and jewels than a Tiffany's store.

From diamond pendants to emerald earrings, you're nobody on the red carpet if you're not wearing some serious money around your neck.

Reaching sky high prices (we're talking millions of dollars here people) celebrities' awards show jewellery usually costs more than the house we live in added to the value of everything we own inside. Plus the car outside as well. And maybe next door's too.

So how expensive can things get? Answer - pretty damn expensive.

Counting down from the more reasonably priced ($2.5 million counts as reasonable, right?) to the whopping $30 million winner, read on for the ten most expensive pieces of Oscars jewellery of all time...
