If you're tired of finding plastic toys or paper hats in your Christmas crackers then perhaps you should consider upgrading to table accessories hiding luxury treats such as yachts and cars.

Luxury website VeryFirstTo.com has launched a bespoke range of what are being billed as "the world's most expensive Christmas crackers", containing extravagant gifts.

With treats including a Cartier 18-carat white gold long necklace set with 20 diamonds, a Breguet Tradition wristwatch in 18-carat rose gold and an Aston Martin Vanquish Coupe, you'll want to make sure that you're on the winning end of the cracker when it comes to Christmas dinner.

Additional prizes include a limited edition "Pen of the Year" from Graf Von Faber-Castell, inspired by the architecture of the New Palace of Sanssouci, and the "1 Like No Other" trip of a lifetime traveling to 10 global locations such as the Wisteria Tunnel in Japan and the only Ice Igloo hotel.

The most expensive item in the crackers is the Predator 84 yacht from Sunseeker, whose key fob is hidden inside the crackers.

At US $6,291,802 for six, the crackers are rather pricey - but they do come in a range of colours and can be ordered to suit your table décor. Available from veryfirstto.com
