A US department store may have the perfect gift — a $75,000 yurt. A luxury version of the tent usually associated with Mongol nomads is one of the fantasy gifts in the 2011 Neiman Marcus Christmas book. At 18 feet in diameter, the hand-painted yurt is “the ideal simulation of a genie’s posh bottle,” the catalog says. The portable structure includes one-of-a-kind designer down-filled pillows and a crystal chandelier. Not interested in nomadic outdoor living? How about a $125,000 custom-built library from luxury book publisher Assouline? It has custom-carpeting, objets d’art and framed prints, as well as 250 current or vintage books of the customer’s choice. For those with a bit more to spend, there is a $420,000 international flower show tour, arranged by JetWay private air. The tour, for 10 people, begins at the tulip festival in Merges, Switzerland, and makes stops at the Kifissia flower show in Athens, the Altera rose festival in Avignon, France, and the Chelsea flower show in London.
