Rock-It is a reddish pink polish with large, slightly duochromatic shimmer flakes. The base is very magenta, but the golden flakes make it look more red once opaque. This is three coats and no topcoat. Application was alright, but I really dislike having to add a third coat. It dried fairly quickly though, so no complaints there.
Rock-It was part of the Mineral FX Collection back in 2011, and I picked this bottle, and several others, up when I was in Riga with a friend of mine. I was very disappointed in how little of the duochromatic effect was picked up by my camera. I might have needed two different light bulbs for it to really show, but it’s still a very pretty polish!
