Blue & green glitters applied in patches on a black base with carefully painted pearly silver shimmer (or white) lines on top. Get yourself one stunning cracked art glass look! Experiment with other bases to get different dominant colors in the look.
I used a dotting tool for this nail art mani. The base color has amazing prismatic effect. Nail Polish: A England - Ascalon, Essie - No More Film, Essie - No Place Like Chrome, Seche Vite - Dry Fast Top Coat
