Happy Friday! Just a simple swatch today... Essie Aruba Blue is a beautiful shimmery royal blue color. Essie describes it as "a frosty sapphire blue" on their website but I don't think it looks like a frost. Sapphire yes though :) I love how it's a bit darker at the edges and kind of glows in the middle of the nail when the light hits it. It went on easily and I didn't have any issues with application. Shown is 2 coats. I layered over this so I'm not sure how long it lasts.
