Cloisonnet, China, 16th century?

Who thinks about the authenticity of the clausone? Are there any Chinese or Chinese experts here))?I exhibited an object on one historical forum, one answered me that it was either a copy of the 20th century, or an original object of the 16th century, but doubted the authenticity due to the fact that it was made rudely.But the style of the late 16th century.But I don't know about hard work.I found this as an example:

I would say that this item looks more roughly made))?But in terms of the state and appearance of the enamels, the objects are similar))?

 

What do you think of this cup? Looks old too.The seller said that she was allegedly 18-19 centuries.
