Plum blossom jade, also known as jade, is produced in Shangdian Town, Ruyang County, Henan Province, a "Yangshao Cultural Site", and is named after its colorful plum blossom patterns.

Liu Xiu, Emperor Guangwu of Han Dynasty, once named this jade a "national treasure". Plum blossom jade is delicate and crystal clear, with a dark background and vivid plum blossoms. Fitness balls, jade bracelets, tea sets, wine sets, stationery and other handicrafts made of plum blossom jade shine with noble and elegant brilliance, and are called "Oriental Emerald".
