CULT BUY: The nail polish so popular, one bottle sells every two minutes.

Rose gold: it’s everywhere. From your $39 scented candle to your delicate arrow-shaped ring, the metallic shade is well and truly on-trend.

So it’s no surprise, really, that a nail polish in the eye-catching colour is selling like hotcakes.

From a company with a strong reputation for a chip-free finish, Sally Hansen’s Miracle Gel in Terra-Coppa is so popular that one bottle of the stuff is sold every two minutes in the US. Seriously.

Listen: Should we let our young daughters get manicures? (Post continues.)

It’s estimated 10 percent of the country’s population owns a bottle, as more than 32 million have been sold, Today reports. Yep, one in 10 people own one brand of nail polish in one specific colour.

So it’s got to be good, right?

Well, fun-yet-neutral trendy shade aside, the strength of the nail polish is what gets customers raving.

A quick look at reviews Sally Hansen’s website shows most users find the brand outlasts competitors and is as quick-drying and chip-resistant as it claims.

“Normally nail polish won’t stay on my nails and I’ve tried many brands of supposedly long wearing polish and other gel polishes (that use UV light lamps). This gel polish is sensational because it actually works! Super happy to have found this product,” read one review.

It’s also backed by experts, claiming an Allure Best of Beauty award in 2016.

And the price? Sally Hansen’s Miracle Gel in Terra-Coppa retails for $16.95 (but you can get it from Chemist Warehouse for $13.99.) Sounds like a good deal to us.

Recent presidential elections aside, it’s hard to argue with the choice of millions of Americans.
