This is a part of the Cast Away collection from...I want to say a month ago? Two months ago? Sinful Colors releases collection pretty constantly so I have no idea. It's the one named after the Greek Gods. Neptune is a dark blue (but not really navy) with lots of shimmer. The shimmer range from blue to silver to a hint of pink in it. Thinking about it, it kind of reminds me of OPI's ...Herring Problem, only darker. And a bit less shimmer. And for less. Very very pretty though.
BB Couture's Carrie, but that was darker. I really like this! If you like blues and shimmers and polishes that you can get from anywhere for $1.99 then this is for you.
(Note: All the little mess ups on my nails (mostly pinkie and pointer fingers) isn't because of the polish. It's because I'm a clumsy butterfingers and dropped the brush while I was painting, knocking my nails against a table, and getting blue nail polish all over my white shirt. After that I wasn't going to start from scratch again.)
