NK Blue Sapphire and Sinful Colors Secret Admirer

I felt like wearing something dark on my nails, but not completely black, so I layered NK Blue Sapphire over Sinful Colors Secret Admirer. It came out extremely sparkly, because both have microglitters. In extreme light, it is a gorgeously bright blue, but under regular light, it is black with a blue hue. Amazingly, this mani took only 2 coats of nail polish, one from each polish.
