This is another one of those polishes that isn't around anymore:-( I'm really glad I've held onto it though, it a beauty. I loved the prism polishes, I still have a few, I was really sad when a red/gold/green duo chrome one (I forget the name) dried up and had to get tossed. Turquoise Opal is hard to describe, it looks just like the wings on a Japanese beetle. It turns from turquoise to emerald green to purple. It goes on pretty thin, I usually use 3 coats when I wear it alone. I really like it 2 coats over a black base, that really brings out the colors. This color is hard to capture, as I moved the nail and it changed, I couldn't get the rainbow spectrum on the nail, but in the different pictures you can see how it changes.
