World’s Most Expensive Hair Straighteners

Straightening hair will never be as luxurious again once you use these limited edition Models 1 Diamond Straighteners. Embedded with six Dutch rose cut diamonds and set in 18 carat yellow and white gold they are retailing for a cool £9,500 ($17,575) at London’s Selfridges.

Given that diamonds conduct heat faster than any other substance, the plates of these straighteners have been designed to incorporate crushed diamonds that can reach temperatures of 232 Celsius, a full 2 Celsius higher than the best professional ceramic straighteners.
