First of all, these photos are so bad that it makes me laugh. Why am I squeezing my poor ring finger like that?? Anyway, this beauty is Jesse's Girl Firefly over Wet 'n' Wild Black Creme. Firefly is such a pretty and versatile polish; you could pretty much layer it over anything and it would be gorgeous. The iridescent flakes in it flash yellow, orange, and green, most of which you can see in the first photo.
This second photo is generally how my nails looked when I was indoors, a sparkly dark green. This is one of the prettiest combinations I've worn in a while. I bet Firefly would look good over a dark blue or purple too... hmm...
