I tried it and I love it - here is what I made:

If you like it, let's see how can you do it 😉

STEP 1: Prep your nails and pun on some good base coat (I use this one: https://www.essence.eu/products/nails/nail-care-repair/e/product/nail-hardening-base).

STEP 2: Pain all your nails except one in white (the nail polish I use is this one: https://www.opi.com/color/nail-lacquer/alpine-snow#MX8Z1AzIxopVyuhH.97)

STEP 4: Take a mini brush and using some acetone smudge the black lines that you made earlier. 

STEP 5: Using a sponge, tap some white nail polish on your smudged black lines - but don't use too much white, so that you still have some grayish color left on your nails. Don't worry if you get some of the skin around your nail white, you can clean that up later 🙈

STEP 6: Draw some black lines over the darkest grayish parts of your nail, again mimicking the marble. I used Essence nail and cuticule tattoo liner (https://www.essence.eu/products/nails/nail-art/e/product/nail-cuticle-tattoo-liner-1), but ou can use the thin brush and black nail polish from before.

STEP 7: You're almost done! 😃

Now just make a triangle at the base of your nail with a silver line. I used this nail stickers (https://www.essence.eu/products/nails/nail-art/e/product/metal-stripes-nail-stickers-04), because the lines they make are super straight. But you can also use a thin brush and a silver nail polish. Next paint your plain nail with a silver sparkly nail polish (I use this one, and I'm in love with it: https://eleven.se/en/isadora-sugar-crush-nails-100-diamond-crush-25613.html). Use the same nail polish to color the triangle at the base of your marble nail.
