Black Emerald is incredibly beautiful. It's an emerald green shimmer polish with burgundy duochrome. In the bottle you can sometimes see a gold shade, but that doesn't transfer to the nail. Still, I loved this polish! I used two coats with a coat of Seche Vite. I don't know if these polishes are three free, but it didn't smell like it. It seemed like any other polish to me.
I actually ordered a few more Brucci polishes after I received my first order. I haven't tried any of the other ones, but the colors are so beautiful and they were only 2.35. I just can't get over how cheap they were. The cremes look so scrumptious and I really hope they are as awesome to apply as the look in the bottle. ^_^
