If you ever run across these polishes in a sale bin somewhere grab them immediately. They are gems. This one is Emerald Amethyst and its gorgeous. It doesn't really look emerald, more olive/gold and amethyst, but whether the name is suited to the color is beside the point! you can see the color change on the bottle in the first picture. It goes from a dusty purple, to a gold green , and even picks up a little rosy mauve in there. It needs 3 coats like the other prisms, because they are a little on the thin side, but they wear really well.
I think next week I'll show another prism, Purple Diamond, a lilac holo!
