OPI DS Mystery - $7 at transdesign.com
I adore the OPI Designer Series line of polishes. While it's true that most of them are holographic, even if it's just a bit, there are a few that aren't holo but are just plain cool. DS Royal is one of those, and Mystery is another. I've been debating over Mystery for some time and I finally just bought it off eBay. I got mine for about $10 total including shipping, so basically less than retail if you were to get it at Ulta or some such place. The polish is a bit different than I imagined from the bottle, and I haven't seen (or really looked for online swatches for) it so I was a little surprised. It's a lot more opaque than I thought it would be with all that shimmer in the bottle. The first coat reveals that the base is a very deep blue-toned purple with some translucent large shimmer particles. The weird part about this polish is that inside in indirect light the shimmer is gorgeous! It's like lots of autumnal green-gold and brown shimmer running through the base. Then you go outside and half the shimmer disappears and blends into the base but there's a little bit of copper-toned shimmer peeking out. I only really like this polish when it's not in indirect light. I think this would be a lot better for the winter months when there isn't much sun. This polish didn't blow me away, but it's got some nice qualities.
