The 6,000 pearls used to make her custom Calvin Klein Collection dress (basically a piece of jewellery in itself) cost $199,110 alone.

7. Margot Robbie

Robbie's vintage Van Cleef and Arpels necklace took 600 hours to create using 150 diamonds and 300 sapphires set in 18-carat gold. It was originally made for the Duchess of Windsor in 1938 and is known as the Zip Antique. Its value: over $1.9 million, which Robbie described on the red carpet as "worth more than my life".

3. Nicole Kidman

A shopping spree at Harry Winston for the jewellery worn by Kidman on the red carpet will set you back more than $9 million. This buys you seven-carat emerald-cut stud earrings, an 82-carat "caftan diamond" bracelet and two diamond platinum-set rings.

1. Cate Blanchett
The stunning turquoise, aquamarine and diamond bib necklace is so pricey, its maker, Tiffany and Co. will only reveal the price upon request. With that many stones, it's sure to have a lot of zeros in its price tag.
