This is a Chinese vase with a smooth and luminous oxblood glaze accented with light purple areas. This finish is known as a flambé-glaze. It features a long narrow neck, pronounced base, and sculpted lip. The sculpted lip is unusual in this kind of vase; often it is more lightly glazed and smooth.
It is similar in color and shape to vases produced during the Qing dynasty in China (1636–1912). Specifically, this vase matches many made in the 18th century. The vase is in very good condition. The seal on its base indicates that it was produced during the reign of the emperor YongZheng (1723-1735).
Based on average sales of similar items, the Fair Market Value is $200 to $300. However, I urge you to have this examined by an expert in flambé Qing ceramics, since it could be worth significantly more if verified as authentic.
