Guests can enjoy morning pastries, a meat or fish board, their choice of Brunch main including bavette steak in red wine sauce or eggs royal and finished off with desserts such as freshly-made waffles or chocolate ganache tart. Along with all of this, every guest will sip on a glass of Dom Perignon Champagne with which at the bottom shall hold a diamond, only one of which shall be a real, full-cut brilliant diamond.

Once guests have finished their champagne, they shall take their stone to the on-site diamond inspector to discover if they hold the true diamond, with the winner being announced at the end of the day.

An event for the elegant and indulgent, you'll also be treated to the impeccable 360-degree views on offer at Searcy's in the pinnacle of the Gherkin.
