First is an untried polish called Gem Green from CQ. I picked this up probably a year or more ago. I haven't seen the brand around stores lately and I wonder if its still being made. Anyone know?
Pictured is two Coats; very easy to apply. Its kind of a sparse/scattered holo. It really needs bright sunlight to show the rainbow, but its a pretty shade of green indoors too.

I topped it with NaCl from Urban Lacquer. (italics are the shop's descriptions)
NaCl is a gorgeous, color-changing blend of white and iridescent glitter - 8 different glitters, to be exact. Looks beautiful over any base color! This formula is thick, and almost has a fluffy texture. It glides easily onto the nail, and is a wonderful addition to your winter polish collection!

I just love square glitter and this topper has plenty!
Little Black Undies (LBU) is a basic black polish that can be worn by itself, or under a glitter polish.

Two coats with topcoat and it was perfect!
But wait! How would it look with NaCl on top?

eeee! More squares! :D
Hurry Me Up is a unique blend of micro iridescent pink flakies, neon yellow hex glitter, and black shredded glitter in a clear base. Works best as a glitter topper, although can be worn alone, when applying 3-4 coats. The micro pink flakies will shift from pink to purple, and is a perfect "going out" polish!

Two coats of Hurry Me Up over Loreal Tea and Crumpets. Such a fun polish full of tiny shreds, pink glowy shimmer and teeny matte glitters! :D
