It is from the Winter 2013 Zenith collection.
Pictures are 3 coats with no topcoat. It is not opaque at 3 coats. You will likely need 4+ thin coats for it or will see visible nail line with it. This polish is almost hard to tell if it’s white or silver when you look at it. Very pretty.
This is a currently available polish from Zoya.
Seraphina can best be described as a full-coverage, Polaris silver metallic.
