This is a rare yellow-ground enamel vase in the shape of a moon, dating back to the Yongzheng period (1678-1735). The handles are shaped like two ruyi (a traditional Chinese symbol of good fortune), making it a masterpiece of court art. Both sides of the vase are decorated with lotus patterns. This vase represents the highest level of porcelain craftsmanship during the Yongzheng period of the Qing Dynasty. It stands 41 cm tall, with a large, crescent-shaped body, exquisite workmanship, and complete decoration, covered entirely with intricate floral patterns. The two ruyi-shaped handles symbolize good fortune and auspiciousness. The base is inscribed with the four characters "Made in Yongzheng." In ancient times, yellow was the exclusive color of the emperor; this exquisite porcelain vase is extremely precious and a unique artistic treasure.
