6. Diamond Cocktail – Sheraton Park Hotel (London)
Most drinks that made this top 10 are either made with rare fine liquors or they come with a diamond relish. The Diamond Cocktail is definitely part of the second category: the intense concoction is served at the Sheraton’s 5-star London property. It is a blend of cognacs that fetch about $1000 per bottle and Charles Heidsieck Vintage 2001 Champagne plus a real diamond.
The amazing thing is that once you order the drink you can choose your stone, and even swap it out for a ruby, whatever you prefer. The price of course depends on the jewelry, but it usually starts at $4,350.
