The name really says it all, this polish has the look of a tahitian black pearl. It's a grey base with dark green shimmer, which gives it that pearly finish, it is part of the three new shades that they introduced : Peche Nacrée, Blak Pearl and Pearl Drop. I am really wanting peche nacrée too.
This one looks a lot to the greener side in the bottle than on the nails. It is definitely not worth the 18 € I paid for it, but it is still very pretty. I think Sam from Fashion polish did a comparison with an opi. The application was great, I didn't really like the streaks, and I am not a fan of their brushes, I prefer OPI or Dior.
