The earrings each feature a pear-shaped fancy light-yellow diamond, weighing approximately 52.88 carats and 51.46 carats and with VS1 clarity and VS2 clarity, respectively, suspended from a circular-shaped colorless diamond, which is suspended from an oval-shaped light-yellow diamond surmount, mounted in white gold.
