To create nail art that looks just like the marbling on a turquoise stone, don't try doodling the veining — just use a piece of plastic wrap. You'll want to start with a dry aqua manicure (we recommend doing this the day after you polish your nails turquoise, so you know the lacquer is hard), then grab a piece of plastic wrap. Crumple it so there are a lot of wrinkles and folds, and take a gold polish and dab it onto the crinkled plastic. Press the painted plastic into your nails like you would an ombré sponge. Once you lift up, you'll reveal the pretty marbling effect.
