This stunning nail polish by Chanel came out last year and has been a bestseller ever since. It's a black- grey with a strong green pearl with a glossy finish. Application is pretty opaque and you need about 2 coats to get good coverage. I find these last about 3 days on me before chipping which is about average on me.
This really is a beautiful nail polish it's no wonder that so many brands follow Chanel's lead and this one is particular is such a modern classic.
