Hour Glass

If you're tired of dropping your hourglass and spilling all the sand inside, a little shop in Thailand has a solution for you.
They replaced the sand with diamonds, 10,000 carats of them so if you drop this hourglass, you'll at least be motivated to clean up.
Before you go booking you ticket to Thailand, we should mention that the price tag on the world's most expensive hourglass is a messy $6,400,000.00 USD.
