From the photos would you call these dupes? I guess it all comes down to what micro level do you want to get down to. To the plain eye, and possibly a non-nail polish lover, they may all seem to be exact matches. But to those that are probably taking the time to look at a blog devoted to nail polish, they probably want to get to the nitty gritt. So that said, let's discuss the differences.

Orly - It's Not Rocket Science

• Most opaque
  
• Most shimmer and duochrome
• Best application (two coats does it, three coats for *wow*)

SpaRitual - Optical Illusion

• More olive, moss colored than the other three
• Least concentration of shimmer, duochrome
• Thinnest formula
  

China Glaze - Zombie Zest

• Cheapest of the three
• Finest shimmer, duochrome (more concentration than SpaRitual)
  
• Thinner than Orly, better application than SpaRitual
  

I hope that this is helpful! My pick is the Orly and I think the China Glaze over black would look very pretty.
