Zoya Gemma is little odd if you ask me. There is a big chance you love it or hate it.
The color is dirty olive green and has beautiful blue shimmer. And shimmer is the reason you love it or hate it. I must say that this is unusual combination. And honestly I haven't decide if I like it or not.
As far as application goes, I had no problems. Two coats and I might add the one coat more, but it is opaque enough in two. Also it dried fast.
First picture is taken in shadow, last two on direct sunlight.
I absolutely love shimmer in last picture, such a special polish. Do you agree?
