I began by applying 2 coats of Zoya Tiffany, a peach-copper foil that was released with Zoya's Fire & Ice Collection. Tiffany applied pretty well; the foil particles made it less smooth to apply than say, a creme, but overall the polish had a good texture.
Next, I applied 1 coat of OPI Silver Shatter. This was my first time using Silver Shatter (or any shimmery crackle polish, for that matter) and it took me a few nails to get the application right. In order to make sure that the polish cracked well and my base color showed through, I was doing pretty thin coats of Silver Shatter, but unfortunately they were too thin to crack properly. Once I started using slightly thicker coats, however, the polish "shattered" well.
I really liked that Silver Shatter was more of a foil than a straight shimmer, and I'm looking forward to using it over other polishes (I think it would make for a pretty look over dusty pastels, similar to those in the OPI Pirates of the Caribbean collection it was released with). The only downside to this polish is that it has a tendency to get goopy pretty quickly when it's exposed to air, so if you wipe off your brush on the bottle neck like many of us do, you'll probably need to wipe the bottle neck down with remover before you put the polish away.
Finally, I topped the whole manicure off with 2 coats of Sephora by OPI Traffic Stopper Copper, which I bought after seeing kittytokaren's beautiful manicure of TSC over a nude. Traffic Stopper Copper features both small copper glitter and larger, hexagonal copper glitter in a clear base. The glitter in TSC isn't too densely packed, which makes it perfect for layering, and I though it providing a great finishing touch to this shiny silver and copper mani!
