Serena Williams proves that Messika's exquisite fine jewelry can be worn for a variety of occasions - the tennis star was spotted wearing a pair of the designer's earrings during a French Open match. Handmade from polished 18-karat white gold, this signature 'Move Noa' bangle is encrusted with 1.25-carats of shimmering diamonds. The slender silhouette makes it perfect for stacking with other styles from the collection, too. Each Messika piece comes with a two-year warranty, which is activated 28 days after purchase. To receive an additional year's warranty, register your piece on Messika's website.
