China Glaze Haunting is a pretty black polish packed with silver glitter. The formula is great! All you need is two coats. Haunting is from the China Glaze Haunting Halloween Collection 2011. China Glaze Haunting retails for about $6 online.
The dupe I found for China Glaze Haunting is Petites Midnight Frost. It is also a black polish with silver glitter. The only difference is that CG Haunting has a lot more glitter and you can see that from the bottle. But the color is pretty much the same. I used 3 coats because the formula is a tad bit more watery than CG. Petites polishes retail for about $2, so it's a bargain!
