The Life: It contains 267 carats of crushed black diamonds - and at $250,000 is the most expensive nail polish in the world.
At $250,000 a bottle, black nail polish could leave you in the red
At US$250,000 (Dh918,250) for a 15ml bottle, it is officially the world's most expensive nail polish. Containing 267 carats of crushed black diamonds, the varnish was created by the Los Angeles-based luxury jeweller Azature and is aimed at the world's wealthiest, the "1 per centers".
Limited to just one bottle, the polish has a platinum cap that is studded with 60 black diamonds.
Azature, whose products are available to buy in the region at Harvey Nichols in Saudi Arabia, called the unusual rock the ultimate fine jewel.
"Its combination of beauty, mystery and sophistication makes it a timeless luxury," he says.
"One day, I thought, 'Why not showcase this style on nails?' So I developed a black diamond nail polish with the same attention and quality as my jewellery in order to preserve the elegance of the black diamond."
A couple of months ago, Kelly Osbourne caused a stir when she wore the polish to the Emmy Awards ceremony.
"I've been so scared to touch anything because it's powdered black diamonds … worth $250,000," she said at the time.
"I'm the only person they let wear it, it's in a safe upstairs in the hotel room. I couldn't believe it. I have not touched a thing all day."
Ms Osbourne later attempted an apology on Twitter for her ostentation.
"I see that my nail polish has offended some of you, however, I see your point, but it was a once in a lifetime experience #MyApologies. Please forgive me for not regretting it. It made me feel like a queen."
The jeweller counts celebrities including Beyonce and Rihanna among his clients.
But if you do not have their bank balances, do not fear.
A cheaper version of the polish by Azature is also available for $25. The company says it, too, contains black diamond, although how much is not specified.
