Rose Mini Christmas Tree

While most of the trees on the list have been tall, Takashimaya went the opposite way to show that size isn't the only factor in attracting attention—and money—when it comes to Christmas tree glitz.

Takashimaya managed to compress the Rose Mini Christmas Tree to a measly 40-centimeter/16-inch height, clustered by a little tower of preserved roses looked over by a bear, based on a concept by Parisian flower store Claude Quinquaud. Diamonds from Australia and Africa are embedded in the petals of each rose. They lay on the petals like drips of dew, quenching another kind of need for anyone willing to part with USD 1.8 million. The bear's partner isn't much better: it's a diamond pendant that twinkles like the stars overhead.

According to the department shop, Rose Mini Christmas Tree is 40 centimeters (16 inches) tall and contains roughly 100 carats of diamonds from southern Africa and Australia.

Cost: $1.8 Million
