While not everything that glitters is gold, the sparkling new polish from celebrity manicurist Deborah Lippmann most certainly is.

Instead of metallic plastic, the festive sparkle in Boom Boom Pow, £18, was created by including shavings of real 24-carat gold.

And with famous fans that include Lady Gaga, Lena Dunham, Kelly Clarkson and Sarah Jessica Parker, the luxury lacquer has already secured the A-list seal of approval.

But Boom Boom Pow isn’t the only Lippmann polish to contain an unexpectedly expensive ingredient: also available are polishes that contain powdered diamonds and crushed pearls.

As a result, the brand has become a regular on the fashion circuit with Valentino, Bulgari and Burberry among those to enlist Lippmann for their shows.

The manicurist has also created bespoke looks for some of the biggest celebrity names in the business.

Among the A-list approved hues are Lara’s Theme, a bright orange-coral created with the help of model Lara Stone, and the glamorous deep-red Just Walk Away Renee, which was originally made for Renee Zellweger.
