With a quarter of a million dollars, you could buy a lot of things.

You could purchase a home, a super-fancy car or a college education for your kids. Or, if you're feeling a little more adventurous, you could always go on a shopping spree at Hammacher Schlemmer and buy that submarine shaped like a killer whale that you've always wanted.

But if you already have all these things and just can't imagine what you're going to do with that $250,000 in loose change you have lying around, then this uber-splurge item might just be for you.

Jewelry couturier Azature -- the self-described "Black Diamond King" -- is now producing a one-of-a-kind bottle of diamond-infused nail polish, Fashionista reports.

Containing 267 carats of black diamonds, this luxe lacquer will set buyers back a quarter of a million dollars.

The Hollywood-based Azature, whose jewelry has adorned stars such as Rihanna and Beyonce, has called the black diamond the "ultimate fine jewel."

"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 jewelry in order to preserve the elegance of the black diamond," he said in a press release.

With its hefty price tag, Azature claims its valuable varnish is the "most expensive nail polish in the world," usurping the $130,000 Gold Rush couture nail polish that British jeweler Models Own released last year, Fashionista notes.

Want the glitter without the gold? For the 99%, Azature is also offering a department store version for $25. According to an Azature spokesperson, this wallet-friendly version has a real black diamond in each bottle. It will be available at Fred Segal in August.
