Tiffany & Co. recently lit up Milan’s Piazzo Duomo with a tree that cost more than $450,000, making it the most expensive Christmas tree in Europe. Ever. There are more than 100,000 electric candles adorning it, as well as specially-designed decorations by the jeweler. Tiffany will also have a pop-up shop of sorts underneath the tree selling “gifts.” And a very Happy, Sparkling, Tiffany Holiday to you!
