I searched around everywhere for this polish! It's Revlon's Carbonite which is considered a close dupe to Chanel's Graphite. I don't own Graphite so I can't compare it, but you can look up swatches online :-) Carbonite is an amazing polish, it's a one coater as well!
It is a gray/silver/foil full of awesomeness. The reflection on this polish is great, it almost looks like you have on textured tin foil but gray. It looks textured but really it's smooth. I love the dimension this polish has.
It reminds me of granite or some kind of pattern/texture you'd see inside a rock. I don't own anything like this which makes me super happy :-)
So if you don't want to drop the cash on a Chanel polish, here's a good alternative :) ... if you can find it that is!
