NEW YORK (CNNMoney.com) -- Forget gifts for under the tree, this holiday season give something that goes under the sea.

Neiman Marcus unveiled its 2007 Christmas catalog of unusual holiday gifts Tuesday, which includes U.S. Submarine's $1.44 million Triton 1000 that dives up to 1000 feet underwater, in addition to a $1 million 305-carat uncut diamond necklace and a his-and-hers chocolate portrait, all in honor of the luxury retailer's 100th anniversary.

"This holiday season is a special one as we celebrate our 100th anniversary," Brendan Hoffman, president and CEO of Neiman Marcus Direct, said in a statement.

And this year's spare-no-expense fantasy gifts are definitely for those who like to think outside of the (gift wrapped) box.

For instance, the custom his-and-hers portrait by Vik Muniz, available for a sweet $110,000, is composed with chocolate syrup.

Also of the organic variety is a $30,000-dragon topiary for the front lawn, complete with blown glass eyes and gold leaf horns, claws and teeth.

But those that really want to their give their neighbors something to talk about can invite them to a private classical concert hosted by Regis Philbin, to the tune of $1.6 million. The Kirov Orchestra will perform holiday favorite the Nutcracker Suite, along with the Tchaikovsky Piano Concerto and another masterpiece of their choice.

Alternatively, adrenaline junkies can buy their very own rocket racing team (with pilot) for $2 million.

Bck on terra firma, there are 10 acres of secluded land among the mountains of Paradise Valley in Montana, up for grabs for $2.3 million. And to handle the rough terrain is a 2008 Lexus IS F limited-edition sedan, with a 400-horsepower, V8 engine that sells for a swift $68,000.
