This combo was pretty great. I did two coats of Zoya Raven which is a solid black creme and it has a hint of shimmer but it's barely there. This was from their trio that included their 18K gold top coat. Over Raven, I did one coat of Ozotic 505 which is a duo.....chrome.... shimmer? It's not exactly like one of the China Glaze Bohemians over black because it has that shimmer to it so it doesn't feel as "oil slick" but rather more shimmery. It's a cool combo, you can see where the turquoise to purple to blue happens depending on where the light is hitting it. Still one of my favorite top coats over black.
