EDITED: I went back and revisited this polish and I guess my tastes have changed, or my expectations changed, or sitting in the bottle made the polish change (probably more the first two and not the third), because I like it much more now. I'll edit my review to reflect that, though some of my complaints are still valid, so I'll leave them.
Some blue and lots of silvery glitter suspended in a indigo-leaning, dark blue jelly base. Sounds great, and the swatches I saw looked great, so I picked up a bottle of this, but my feelings are a bit mixed.
On its own, over clear base coat, it's nowhere near as dark as I'd like to have seen. It's more of a medium-dark, cool blue than a real midnight or navy blue. I'm a huge fan of glitter nail polish, and I love having blingy fingers, but my initial reaction to the silver glitter against the medium blue base was that the contrast was off. Now I think of the glitter as more of glitter plus silvery surface iridescence, I kind of "get" this polish a little more, and can appreciate it for what it is (rather than what I was expecting).
I would like to have seen more blue or even black glitter in this. I think it would have balanced the silver a little more and really let the blue base stand on its own.
I've also found I needed three coats of this to get decent opacity and coverage (very unusual for me). The formula is okay, pretty much what you'd expect from a China Glaze jelly, in that it goes on quite thin and streaky at first and builds up with additional layers. Not too difficult to work with. Like many (most? all?) jelly base polishes, the tips wear really quickly, at least for me. I eventually tried this over a dark blue base colour and that solved the opacity issue, and it fixed some of my complaints about the base not really standing up to the glitter.
Removal is fairly straightforward, not as much hassle as a full-on glitter polish, so that's nice, at least.
