I started with a base of Nails Inc. Whitehall, a teal magnetic polish. Magnetic polishes are made up of metallic particles in a polish base, and when a magnet (usually comes with the polish) is put over the wet manicure, it pulls the particles into a pattern.
Then, I added a coat of my gLORIous 22k Gold Leaf Topcoat. I was a bit impatient on this step, so I ended up making some minor smears on the magnetic polish below. Oops! Still looks cool though. :) Anyway, this is real gold, so it definitely qualifies as metallic.
I love the way this turned out. I was a bit doubtful that this idea would look good at first but I am really quite pleased. Teal and gold always look great together, and the darker black areas of the magnetic polish make for some great contrast.
I bought the Nails Inc magnetic on sale on Sephora. Purchasing information on the 22k gold leaf topcoat can be found here.
