Pantone must have been thinking of our Emerald City when it declared the hue the color of 2013. But before you rush off to replace your wardrobe's corals and oxbloods with radiant emeralds, why not test drive the trend on your digits?

For deep, regal nails try Butter London's nail lacquer in Thames. The color errs on the blueish side of emerald and has warm gold undertones for just a hint of shimmer. This saturated polish takes just a few coats—pair it with Butter's hardwear top coat for long-lasting results.

All of Butter London's lacquers are fomulated without nail-damaging ingredients like formaldehyde, toluene, or parabens. Plus, the polish packaging is entirely recyclable. Talk about green.

Find Thames for $14 at Nordstrom and kick off 2013 with a jewel-toned bang.
