This is the lovely Emerald by Revlon. I'd almost bought one of the greens like this that have come out in the last couple of years, but never did it. I stared at Jade Is the New Black for so long when OPI's Hong Kong collection came out, I must have looked like I was meditating on it. Anyway, I was bingeing on Revlon Top Speeds earlier this Spring, and I bought Emerald on a whim. It's a rich, medium-green creme with blue undertones. The formula is fine, applies smoothly, and dries in a reasonable amount of time. This is also a polish with a shiny finish; I did not use a topcoat for the swatches.
