This rather pretty polish is Illamasqua's Fragile. It's intended to look speckled like an egg (and many of the promo images do indeed feature eggs), combining a jelly like base colour with matte glitter particles in a number of sizes. It's like a more muted version of a Deborah Lippmann glitter polish - glitter showing through multiple layers of polish for a manicure with plenty of depth and variation.
Unlike some of the more interesting instant nail art polishes I've tried recently, I'm finding myself really liking the speckled effect. Probably because it doesn't have a particularly unusual texture. Unusual textures often lead to annoying things like catching on tights, feeling weird when you tap your nails on your cheek when thinking (does anyone else do that?) and causing your other half to raise his eyebrow in a fairly cynical manner.
Anyway. Application was pretty damn good for something so chock full of particles. The polish glides onto the nail smoothly, and there's no need to poke the particles into place - they distribute themselves evenly with no effort at all. This is three coats - the first two were a little patchy on the pale blue base colour, but the third coat evened everything out.
Removal is unsurprisingly awful. It might not be sparkly glitter, but it's still a mixture of chunky bits - it's easiest to soak this polish off rather than scrub the nail.
Illamasqua's speckled polishes are also available in green, pink, beige and purple varieties and I rather think I need the purple one in my life. Find them at Illamasqua counters and stores, and online, where each polish will cost you £14.50.
