Cirque Potosi is a clear polish with a happy mix of glitter types. There's your usual small round silver, of course, but what really makes Potosi shine is the multi-sized polygonal glitter that makes it look like silver shards on your nails. seriously, how cool is this?
The shard glitter is quite new to me - right now I don't really have anything like it in my stash at all! I'm in love with the effect - it's a little bit random-looking, but incredibly eye-catching. Like shattered shards of metal, or a mirror, on my nails.
Here I've layered it over 2 coats of a random nail polish I got from Sasa, Sasatinne SPN103. It's a deep, dusty blue-leaning teal, and I think the two go really well together. I used one coat of Potosi, and did a little dabbing at any empty spots to get a more even glitter spread. So as you can see, the coverage is fabulous.
If you aren't in the US, you can get Cirque polishes from Mei Mei's Signatures for S$16-19 apiece. She ships internationally, too, so great for everyone who doesn't have Cirque in their area.
