Paint all your nails green, except one nail. Paint that one gold.
Create 4 dots, make sure they are pretty thick. This may take a few tries.
Take a took pick and lightly drag it across the wet polish at the bottom of the dot, in the middle.
Keep doing it, and create a lot of clovers. At the edges if your nails, you can add just a green dot to make the illusion of an unfinished shamrock.
Add your topcoat :)
