This week, a bottle of the Dalmore Oculus whisky became one of the most valuable whiskies in history, selling for an astonishing £27,600
But how about a drinking accessory worth even more? The Boston Shaker is perhaps the world's most expensive cocktail shaker, priced at €35,000 (over £31,000).
The renowned flavoured liqueur maker House of Bols is responsible for the pricey and unique shaker, in collaboration with their Amsterdam neighbour Coster Diamonds.
It is made from silver, 18 karat gold and is encrusted with 480 brilliant-cut diamonds weighing 19.05 carats.
The House of Bols is no stranger to ostentatious drinks-related displays - its site doubles as a museum, and won the 2007 Dutch Design Award for Best Exhibition and Experience.
