Dear Jonathan,

Your vase is made in China around 1900 ( Guangxu period ) and is called Nanking ware. This was made in Nanjing ( Jiangsu province ) what has a large production facility for porcelain mainly in 19th and 20th century. Chinese art is sought after on the market due to the fact that Chinese people earn more money every year and are really interested to buy an ancient piece for their homes. If your vase came to auction I would expect it to fetch around the estimate I gave above,
