I've had Stone Cold for quite a long time. Thank goodness I finally wore it! This is three coats here.
The polish has really chunky, flakie-like shimmer. Glass-flecked? It's absolutely amazing in person.
Stone Cold is super sparkly, shiny, and metallic looking but my pictures absolutely do nothing to show that! You really have to see/wear this one in person to appreciate its beauty.
It also has this terrific depth to it. It looks blackened beneath the sparkly shimmers.
