EDIT OR BUY BEACH BLUE AND YELLOW AGATE NECKLACE. Head to beach in this individual seaside holiday blue beaded piece. Teal and canary yellow agate resembles the ocean and the sand, with added accents of pastel peach round beads making up this matinee crescent, Beach Blue and Yellow Agate Necklace. Hand cut, oversized agate slices create uniquely beautiful and eclectic fossil features on either side of the necklace, with divine striations of amber and grey, inky blue and white running through them. Dainty gleaming gold finishings adorns this playfully kitsch piece.
