This is L.A. Girl Rock Star in the color Double Platinum. I have really enjoyed the Rock Star line and this is no exception. I purchased this at a store called Amuse in a local mall for $3.99 but I have seen these polishes at other stores for just $1.99 (obviously after I purchased this LOL). You can get it at Cherry Culture for $2.80.
Double Platinum is a great jelly like silver/gunmetal color with tons of small particle holo glitter. It's got a fantastic oil slick quality to it, in the right light it appears rainbow which is so fun. It's quite difficult to capture in the photos but I tried my best.
The formula is quite sheer so next time I think I will layer this over black or silver.
