Need that one-of-a-kind stocking stuffer and have $1.9 million burning a hole in your pocket? Design your own diamond ring and travel to Africa to see where the stone came from. That's among the unique offerings for sale in the 87th edition of the Neiman Marcus Christmas Book, which was unveiled today in Dallas. Almost 40% of the more than 500 items for sale in the book cost less than $250 (cheapest: $12 mug), but it's the "fantasy gifts" that get everyone's attention. At $1.85 million, the "diamond experience" is this year's most expensive fantasy gift. For that sum, the buyer gets a 25-carat rough diamond from which to make a personalized ring with the help of jewelry designer Maria Canale. The package includes a trip to De Beers' headquarters in London and to Africa to trace the stone's origins.
