They will forever have us in awe.

So you've probably been hearing about the star-studded, all-female cast, Ocean's 8 movie that's in cinemas now. It sees some of our favourite actors (Sandra Bullock, Cate Blanchett, Anne Hathaway, Mindy Kaling, Sarah Paulson, Awkwafina, Rihanna and Helena Bonham Carter) attempt to pull off the greatest heist of their lives! It all takes place at the biggest party of the year - the Met Gala. So much glitz, glamour and, it turns out - theft. This got us thinking - what world-famous, most exquisite jewels are worth remembering Here are some of the timeless celebrity pieces that left us infatuated. 1. The Cambridge Lover's Knot Also known as Queen Mary Lover's Knot Tiara, Queen Elizabeth loaned this tiara to Diana as a wedding gift. It's said to be a favourite too of Duchess Kate, who first wore it in 2016. 2. Kim K's Wedding Ring There's no denying the Lorraine Schwartz 20-carat diamond wedding ring was pretty stunning. However, $4.5 million (€3.9 million) sparkler was stolen during the infamous Paris robbery. 3. Titanic's Heart of the Ocean Remember Leo, his artists sketchbook and that giant diamond and sapphire necklace that was worth a bomb? Well, apparently, the story of that sparkling sapphire necklace isn't all fiction. According to The Washington Times, a married man called Henry Samuel Morley had a giant diamond and sapphire necklace on board the Titanic. He gave it to his lover Kate Florence Philip before she got on a lifeboat,while Morely himself didn't make it. 4. The Duchess of Sussex and her Trilogy Ring November at Kensington Palace was when Harry and Meghan confirmed they'd be tying the knot on May 19. Here we witnessed that gorgeous engagement ring - the centre stone being ethically sourced from Botswana - where the couple first holidayed together. 5. Audrey Hepburn's Tiffany Diamond The famous 1961 film Breakfast at Tiffany's saw Hepburn don a 128 carat yellow diamond from Tiffany's, along with the iconic little black Givenchy evening gown. 6. Kate Middleton's Cartier Tiara  The halo style tiara was made with nearly 1,000 diamonds and was purchased in 1936 as a gift to the wife of King George VI. In the new Ocean's 8, Debbie Ocean and her gang of thieves plans to steal the Toussaint - a $150 million (€129 million) Cartier necklace. Nice! 7. Elizabeth Taylor's Colombian emerald pendant (23.44 carats), part of her Bulgari Collection Taylor had a love of everything Bulgari. The luxury brand even created several pieces for her, one of the most famous being her emerald necklace in 1965. After her death, a two-day sale of Taylor’s jewellery took in around $137.2 million (€118 million) making it the most valuable sale of jewellery at auction, EVER. 8. Marilyn Monroe's Best Friends After the 1953 film Gentlemen Prefer Blondes, the above image marked the first ever moment that a jewellery house, namely New York's Harry Winston's, lent glittering diamonds to a star for an Oscars red carpet do.
