It may be getting chilly outside but these are a pair of boots you want to keep indoors. Antwerp-based companies Diarough/UNI-Design and A.F. Vandevorst have collaborated in creating the world’s most expensive pair of diamond boots, covered in diamonds totaling 1,550 carats. Unveiling themselves at the Business of Design Week in Hong Kong (December 2–7) by Antwerp World Diamond Centre, the paisley-patterned black leather Ankle Boots made in European size 39, feature 4,783 grams of gold and 39,083 natural fancy colored champagne, gray and pink diamonds. The entire process of preparing the boots, from selecting and setting the diamonds took over 30,000 hours.The organization said. A.F. Vandevorst’s cross-shape logo on the boots is made from extremely rare reddish-pink diamonds. Now on sale, the boots are valued at $3.1 million At its Hong Kong unveiling, the boots were showcased to 400 VIPs, including Queen Mathilde of Belgium and Kris Peeters, minister-president of the government of Flanders. Chinese artist Yi Zhou had the honor of taking the walk with the boots, around a catwalk on Sevva’s 180-degree balcony with Hong Kong’s stunning skyline in the background.
