Topshop Glow Eyeshadows ($12 each) can be used as eyeshadow or (SUPER BLING) highlighters, as their duochrome effect is stunning. I'm not a fan of duochromes simply because they often come as loose pigment, but these little pressed pots are easy to muck in with your fingers for max color payoff.
Aside from the fact that they are rather expensive for a brand that specializes in clothing, these little pots are decent enough for a damp brush or your fingers rather than a dry fluffy brush, which doesn't pick up enough color for my taste.
I picked up Shuffle the Cards (rose gold), U-Turn (green), and Wax and Wane (purple). They're really not impressive in swatches but layer incredibly well over a white or black base.
