4. Abu Dhabu Christmas Tree: $11 Million 

Erected in 2010 in a 7 star Abu Dhabi hotel, this tree is certified by Guinness as the most expensive decorated tree in the world.  The 40 foot evergreen is bedecked with gold bows, ornaments and garlands.  Gold wrapping paper adorns the presents at its base.   And it drips precious stones.  Compared to the toilet, it seems almost normal.
