Cloisonne napkin rings

Now I am new to all this so asking for clarification on my thoughts of these 3 napkin rings.
The one on the left is not as good as quality as the other 2 on right in my opinion sloppy finish in. The butterfly 2 have quite nice detail and are finished a lot nicer. So can I assume the butterfly ones are a lot older than the left one. If so what time period would they all be thanks chris

 

Very pretty.
They are all first half of the 20th century, the butterfly ones look the oldest. And I agree, those are of a slightly better quality than the flower and cloud one.

 

Hello...just happened to be scrolling through some old posts. The first one is Chinese cloisonne made in the first half of the 20th century. The last two are Japanese cloisonne from the Meiji Period. Japanese cloisonne are my favorite!
