This is 2 coats of Urban Outfitter's Seadust.
Seadust is a teal green glitter polish with larger blue hex glitter. This is a near dupe to Deborah Lippmann's Mermaid's Dreams. But Mermaid's Dreams seems to have a bit more blue glitter and better coverage.
Brand: Urban Outfitter's
Availability: I bought this in my local store but it can also be bought online
