You've seen an accent-finger image of this, but not a full swatch. I bought it on a whim because I'm crazy-obsessed with night sky polishes (please please please please please OH PLEASE may I have Jessica Twilight? Or Essie SSN. Or Chanel Ciel de Nuit. or Maybelline twinkle twinkle. Or. Or. Or. etc.) so I settled with this one. Five dollars is a lot for a mini, by the way--good for the polish, because I quite like it anyway. This picture was two coats, in the sun.
In truth it looks like a sparser version of my franken, which was chock-full of assorted silver glitter (and, by the way, for some reason all the glitter disintegrated. This scares me.) but had a similar layering effect, where the glitter that's resting on top of a coat looks silver and all the rest become progressively bluer. It adds depth, which I like. I also liked the brush, which is flat and slightly stiffer than most nail polish brushes, and thus very very easy to control. I'm not fond of the squareness of its shape, but it bends to curve easily and I had no application problems.
Here's a thumb shot. It shows my interest in this color best, I think. :)
Blue Sapphire is one of the four polishes I'm allowing myself to use until Easter, but I imagine that it'll disappear quite soon--two coats was somewhat streaky (you can see the color disparity in the first picture). It needs three... once I put it on again (which will be soon) I'll take pictures of the three-coater and make comparisons.
