The mint color in this look is Sally Hansen Xtreme Wear in Mint Sorbet. The light gold color is Sephora by OPI Keep Me On My Mistletoes.
This mani is actually pretty easy to do. There are 2 ways to get this look. The way I did it was painting 2 coats of mint and then free-handing the gold half moon. If you aren't as comfortable with free-hand designs, paint the bottom gold and then use a garage sale sticker (or something circular like that) to create the shape. Then paint the mint over it and peel off the sticker.
