Butter London Thames is a slightly cool-toned, dark teal with a metallic finish. It is a permanent nail lacquer that retails for $15.00 and contains 0.4 oz.
Butter London Thames Nail Lacquer ($14.00 for 0.4 fl. oz.) is described as a "soft, blue-green stunner with just a tiny undercurrent of gold." It's a rich, luxurious green-teal with subtle shimmer. I didn't get a lot of gold shimmer, as it seemed more white/silver to me (even in bright light). I was able to achieve opaque color in two coats. The formula was easy to work with, because it wasn't too thick or thin, flowed evenly across the nail, and didn't streak. There were a few brush strokes in the resulting look, but they were very subtle. I typically get a week of wear with Butter London's formula with a proper base and top coat.
