This is Darling Diva Polish Thunderstruck (Back in Black Collection), a black jelly base filled with silver holographic hexes in three sizes plus silver holographic squares.
Application was a dream, after a good shake even the biggest squares came out of the bottle willingly. I layered two coats of Thunderstruck over a black creme (Manhattan 1010N, what else) and finished the mani with one coat of Nail Pattern Boldness Glitter Food and one coat of Cult Nails Wicked Fast.
Darling Diva Polish are available on Etsy, at Mei Mei Signatures and at Llarowe.
And as I not only love Thunderstruck, the polish, but also Thunderstruck, the song, a short (very poor quality) video I took at Wankdorf Stadium, Bern, Switzerland in June 2010.
