Of course, I wasn't as good at keeping my nails unmessed up back then, so there's some lovely mess here, but you can still how how much they are alike.
As you can see in this picture, the OPI is a 'smoother' shimmer, almost moving into frost territory, while the ChG is a little more 'scattered'. Neither looks black, even in dim light.
Flash reveals the metallic type finish that isn't really so obvious under normal lighting. And you can see that the ChG is just ever so slightly darker than the OPI.
Tomorrow I'll be back with more Nicole polishes, and I've got a few crackles to share in the next few days as well. I'm so not over the crackle trend yet, even though I know a lot of people are. But I've gotten a lot pickier about which ones I'll buy, since I have so many crackle colors and I also like a lot of other finishes.
