Antique Vietnamese annamese porcelain stoneware jarlet.

Decorated with a repeating geometric circular pattern, using grey-blue cobalt underglaze, wrapping around the jarlet's shoulder.

This and similar jarlets were recovered from the famous Hoi An shipwreck cargo, discovered in the 1990s. Total intact porcelain artifacts recovered numbered above 250,000. Pieces unique to the cargo were kept by the Vietnam government, with the remainder auctioned by Butterfields in San Francisco in 2000.

Dates to 15th century CE, during the Le dynasty
