I call this look "Sea Spray.
I still had SinfulColors Greek Isles on. I cut a sliver 1/2"in wide off a dish sponge, dipped it in Greek Isles Neptune and sponge painted 2/3rds the way up my nail. After that dried, I dipped it in Zoya's Trixie and delicately sponged silver on top. Then I finished with a top coat to smooth it all down.
