Hello! My friend has three pieces of blue-and-white porcelain from the Yongzheng period, exported to the Netherlands. The surface of the plate resembles jade. These pieces were used by a Dutch noble family from the 1700s to the 1800s. They survived the First and Second World Wars, which is quite remarkable. A piece in perfect condition is extremely rare. These three pieces have a minor flaw, but they are still very precious. The photos are very detailed; please take a good look. Thank you!
