On the nail, it is easy to tell that they are not dupes. Mer-Maid is a green to blue duochrome shift while The Lizard is a gold to green duochrome. I only needed two coats for full coverage with Mer-Maid, but The Lizard required three to fully cover the nail line. At some point it almost seems as though one picks up where the other ends. The Lizard goes from gold to green... then Mer-Maid starts up with the green and goes to blue...
I hope this little comparison was helpful! Let me know what you think in the comments below :)
Thanks for looking!
