10The Badminton Chest - $36.7 million
No, this is not a simple cabinet where you can stuff your badminton racquets and shuttlecock in. The Badminton Chest is actually named after the Badminton House in Gloucestershire, the seat of power of the Duke of Beaufort. When the 3rd Duke of Beaufort, Henry Somerset, was 19 years
old, he commissioned to have that cabinet built. The cabinet was so intricate with amethyst quartz and other stones that it took 30 experts six years to complete the thing. The descendants of Somerset have since auctioned off the Badminton Chest.
