People with more money than sense can sometimes be amusing, and in the lead up to the Oscars the entertainment press is usually good for some Hollywood-silliness stories.
It seems that the latest fad amongst actresses is for diamond-dust facial scrubs.
The most crowded waiting room pre-Oscars is at the Beverly Hills clinic of celebrity skin specialist Sonya Dakar - where stars line up for her signature £1,000 facial.
Madonna is said to have headed there for a treatment last year which includes a diamond scrub (using diamond particles to exfoliate the skin), an exfoliating skin peel, green tea face mask and red-and-blue UV light therapy to prevent acne.
Diamond particles huh?
Even the oldest, toughest, most dried-out and sun-fried human skin is unlikely to be tougher than pumice stone, let alone the regular quartz particles you find on emery boards. Even Madonna's skin is unlikely to be harder than (say) a steel nail file (6.5 on the Mohs hardness scale, compared to diamond at 10). This is a good example of conspicuous consumption. Diamond dust is quite cheap: I wouldn't be the least bit surprised if the diamond scrub contained less than a dollar's worth of diamond dust.
