Beyonce dazzles in emeralds as she belts the"Star Spangled Banner"

It doesn't take much for Beyonce Knowles to sparkle, but when she appeared to sing "The Star Spangled Banner" at the inauguration of President Barack Obama recently, she captivated audiences far and wide with her stunning hair, gown and glittering emerald fashion jewelry - not to mention her powerful take on the national anthem.

The iconic pop star donned a floor-length black gown with swirling black designs underneath a long black coat that she wore until it was her turn to take the microphone. Her golden hair was parted deeply to one side and curled, allowing her stunning emerald earrings to peek out. The star-shaped stud earrings matched a gemstone ring the singer wore on her index finger, visible as she clutched husband Jay-Z's arm when they walked arm in arm into the Capitol.

Beyonce's jewelry may be "irreplaceable," but you can copy her look with affordable jewelry like the 1.14 TCW Round Genuine Emerald With Diamond Accent 10k Yellow Gold Cluster Button Earrings. This cluster of emerald stones would make a perfect statement paired with a black gown, as would a sparkling cocktail ring like the 5.80-Carat Cushion-Emerald-Cut Genuine Green Amethyst 10k Yellow Gold Ring.
