Or at least it should look like...marble? Or is it more a kind of...splattery nail art? I don't know but still hope you like it. I haven't done a real nail design for a long time. Here's a short step-by-step, without pictures because it's really, really easy:
You need: different nail polish colors you want to combine (I used 3 different!), aluminium foil or plastic wrap, top coat.
♥ 1.) Choose your base color. It doesn't matter what color it is, but it should be on the lighter side. I used a minty light blue. Paint all of your nails with it. You may need 2 coats if it's a sheer polish! Let it dry. Really, don't underestimate it, it should be dry, dry, dry... (; If not you have to repaint your nails, because you'll create a mess. ):
♥ 2.) Crumble some aluminium foil or plastic wrap (saran wrap) to a ball and paint the surface of it with a darker nail polish. You now can use this as a stamp to put the color on your nail. You can be messy, because marble- or stone-patterns are quite individual.
♥ 3.) I took another color to put it over the darker color to have a little more 'depth' on my nails. It's a sheer mint color with golden shimmer (almost like my base color but not opaque plus with shimmer). You 'stamp' this on your nails with aluminium foil or plastic wrap as well. Let this dry! Don't forget to paint a coat of top coat to save your design. I used a quick dry top coat. (:
Very easy, right? :D Try it as well!
I used the 3 colors above: 1.) essence colour & go '146 that's what I mint!' - 2.) essence colour & go '147 miss universe' - 3.) KIKO Quick Dry nail lacquer '834' (seriously, why can't companies be more creative and give their products actual names? *sigh* (; )
I don't know if any of these polishes are discontinued but you can easily recreate this nail design with other polishes and other colors! (: Just be sure to use polishes that have a good contrast so you can actually see the design.
