Sapphire Sparkle is a shimmery top coat that flashes blue and purple. The base is translucent. I used just one coat of Sapphire Sparkle over two coats of Maybelline Onyx Rush (just a basic black creme).
I love the way this transformed Onyx Rush, but is it really worth the high price tag? Probably not in my opinion. But it’s definitely something fun to have in my collection.
There are a couple more pictures below the jump that (hopefully) show the duochrome awesomeness of this polish.
