You need: Q-tips, two nail colors of your choice and a clear polish. I picked Catrice's 'From Dusk to Dawn', Alessandro's crash base, and a clear polish by Manhattan.
Step 1: Add your base color.
Step 2: Dip the Q-tip in a drop of your tip color and gently tab it on the nails. Start at the end of your nails and move inwards so that you have the most dense color at the very end of the nail. That way it fades out nicely and you get that obmre effect. The gold tip should only cover about a third of the nail.
Step 3: Add the clear polish to give it extra shine.
I picked a darker color and an elegant gold for the fall season. In spring you could exchange the base color with a bright pink!
