The world's most amazing green polish was my pick for this festive Irish holiday manicure. China Glaze Emerald Sparkle ($6) is a deep, rich emerald with teeny, bright jewel-toned green glitter. This polish is perfect for so many things: Christmas, St. Pat's, May birthdays (yay for Tauruses!). With a simple golden celtic knot stamped on with China Glaze Passion and Konad plate s06, this may not have been the most creative or unique St. Pat's manicure, but it has been making me super happy. The green glitter has such depth that the chrome-finish golden knot sometimes looks as if it's suspended above the polish. In other lights it looks like gold-painted green velvet. Either way, if you don't have Emerald Sparkle, you need it, hands down. What is your St. Pat's manicure?
