The colors at nightfall are some of the most beautiful of the day. The Nightfall Cobblestone Earrings include deep blue, white and turquoise stones arranged in a cobblestone pattern in the center of the silver tone earrings resembling the sky at nightfall. Small clear cubic zirconia stones add extra sparkle to the design and remind us of the first few stars that appear after the sun sets. Secured by a hypoallergenic post wire.
