Comparison: China Glaze Cosmic Dust vs Born Pretty Hologram Effect #7

So Sally's was having another sale, and OF COURSE I had to get in on it. This purchase was my first bottle of China Glaze! I got Cosmic Dust, which is a medium grey holo.

And I decided to compare it to Born Pretty's Hologram Effect #7:

Coat 1

Hologram Effect #7                                                  Cosmic Dust          

  

Coat 2 

Hologram Effect #7                                                  Cosmic Dust        

Cosmic Dust is very opaque, only needs 1-2 coats. As you can see, after two coats, you can't see the difference between the black bottom coat and the no bottom coat. Hologram Effect #7 is very sheer, and could maybe be a topcoat glitter for a mani. 

Hologram Effect #7 is a little more of a vivid holo, and a little chunkier. It also has a bit of a sage green color in it after it dries, whereas Cosmic Dust is just a straight dark silver.  

Both of these will have its use, and they are definitely nothing alike. I was just curious what the difference would be. Turns out it's like night and day and I'm okay with that :)
